The 12NMB420 is a 12" midbass transducer designed for professional monitoring and sound reinforcement. At the heart of this speaker is a carefully engineered drive system, designed to assure linear, low-distortion output, high power capability and efficient heat transfer. The most extended bass, lowest distortion and best control is usually realized in properly designed vented enclosures. In such designs, the vent, or port, actually provides the lowest octave of output. The vent is driven to full acoustic output by a relatively small motion of the speaker cone itself, acting through the air contained within the enclosure. The excursion of the 12NMB420 at these frequencies is much reduced compared to sealed enclosures, directly reducing harmonic distortion and the possibility of speaker bottoming. Typical vented enclosure sizes range from 40lit up with tunings from 50 to 60Hz; low frequency equalization is suggested and normally added, in order to improve the bass output if the 12" will work without subwoofer. The amplifier size ranges from 250-500W.
The onboard copper sleeve positioned in the gap and coupled with SDR (Single Demodulating Ring) results in optimum balance for reproducing instantaneous peaks on mid frequencies, reducing intermodulation distortion.
The external magnet typology neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange since the external magnet configuration is considerably more efficient than the traditional under - pole magnet topology. This allows to obtain high levels of force factor and power handling with a power to weight ratio at the upper level.
The high quality paper cone has a smooth, curvilinear profile design that eliminates bell-mode resonances within the intended frequency range. This is carried by a specially treated and damped double triple-roll linen suspension designed to control excursion maintaining the piston action linearity.
The 12NMB420 employs a 64mm Interleaved Sandwich Voice coil (ISV), in which a high strength fiberglass former carries windings on both the outer and inner surfaces to achieve a mass balanced coil, resulting in an extremely linear motor assembly with reduced tendency to eccentric behavior when driven hard.

The 12NLW9300 is an extended low frequency neodymium magnet loudspeaker which sets a new industry standard in 12" (300mm) high performance transducers, covering the low frequency band in compact enclosures with high SPL at low frequencies with reduced THD. It is intended mainly as woofer for studio monitoring or multiway systems applications in extremely compact vented enclosures (30-70lit), making it the ideal choice for touring application.
The neo magnet external assembly assures high flux concentration, low power compression and excellent heat exchange. The external magnet configuration is considerably more efficient than the traditional under-pole magnet topology. This allows to obtain high levels of force factor and power handling with a power to weight ratio at the upper level.
The heatsink has been specifically studied according to F.E.A. simulators, improving the necessary heat transfer to the dissipative structure. The direct contact between the heat sink and the specially designed basket, together with the magnetic structure, represents a fundamental improvement in heat dissipation, increasing power handling capabilities and lowering power compression figure.
A state-of-the-art Interleaved Sandwich Voice coil (ISV) voice coil provides high levels of thermal stability and durability. The ISV technology is based on a high strength fiberglass former with half the coil wound on the outside and half on the inside ensuring uniform thermal dissipation on both sides, bonded together using unique high- temperature resin adhesives achieving a balanced and solid linear motor unit.
The 12NLW9300 performances are further improved by the use of Double Demodulation Rings (DDR), designed to reduce dramatically the intermodulation and harmonic distortion whilst improving the transient response.
The 12NLW9300 design features a dedicated exclusive Carbon fibre reinforced straight ribbed cone; the pulp formulation contains special damping fibres and is further treated in-house with a proprietary resin compound in order to increase the cone bend performances 5 times more than traditional celluloses pulp and twice than glass fibre added pulps. The result is a very linear piston action across the entire working range minimizing the destroying breaking modes.
The coating of both the face and back plates is far more resistant to the corrosive effects of salts and oxidization than any other treatment normally in use.

The 12NDA520 is a 12" mid-low transducer created for compact reflex 2-way enclosures and designed to be coupled with typical 1" and 1.4" compression drivers. It can also be used in mid-low applications on modern line-array systems.
Its features and design characteristics make it extremely defined in mid-range frequencies and offer a significant and consistent bottom-end, making the product also suitable for monitoring applications. The 12NDA520 incorporates our proprietary Active Impedance Control technology (AIC), consisting of an additional coil fixed on the pole piece and connected in parallel to the moving coil. The magnetic field generated by this coil has the following effects:
1) Impedance linearization
2) Acoustic and electric phase linearization
3) Significant increase of sensitivity and total SPL
4) Total harmonic distortion reduction
5) Constant power transfer
By not absorbing the moving coil�s electromagnetic energy, AIC offers substantial advantages relating to the quality of sound.
The neodymium magnet assembly developed by Eighteen Sound engineers assures high flux concentration, low power compression and excellent heat exchange since the external magnet configuration is considerably more efficient than traditional under-pole magnet topology. This results in high levels of force factor and power handling with an optimum power to weight ratio.
The curvilinear cone, created from a high damping wood pulp, has been designed to achieve the best possible linearity within its intended frequency range.
The 12NDA520 employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. The final result is an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
A proprietary humidity-block cone treatment makes the transducer suitable for outdoor use in adverse weather conditions. In addition, a special coating applied to both the top and back plates makes the 12NDA520 far more resistant to the corrosive effects of salts and oxidization.

The 12ND710 has been specifically designed for use either as a midbass driver in compact 2-way reflex enclosures or as a direct radiating or horn loaded, dedicated midrange driver, in multi-way touring and fixed installation concert and arena systems.
The neodymium magnet assembly, developed by Eighteen Sound engineers, assures high flux concentration, low power compression and excellent heat exchange because the external magnet configuration is considerably more efficient than traditional under-pole magnet topology.
The magnetic structure has been optimised using our in-house FEA-CAD resource to maximise the flux density in the voice coil gap. Consequently, high levels of force factor and power handling with an optimum power to weight ratio have been achieved.
Direct coupling of the special design basket and magnetic assembly with the large heat sink facilitates thermal flux through the ambient air, increasing the power handling capabilities and lowering the power compression.
The curvilinear paper cone has been created with a special high strength wood pulp designed to achieve the best possible linearity within its intended frequency range and to control bell-mode resonances around the cone circumference. The cone is carried by a multiroll suspension formed from a linen-like material which is more resistant to aging and fatigue than traditional materials.
The already low distortion and sound quality are further improved by the use of Double Demodulating Rings technology (DDR) designed to dramatically reduce the intermodulation and harmonic distortion and improve the transient response.
The 12ND710 implements Interleaved Sandwich Voice coil technology (ISV), in which an aluminum coil is wound inside and outside a high strength fiberglas former, providing a better thermal and mechanical performance than conventional coils.
A proprietary humidity-block cone treatment makes the transducer suitable for outdoor use in adverse weather conditions. In addition, a special coating applied to both the top and back plates makes the 12ND710 far more resistant to the corrosive effects of salts and oxidization.

It has been designed for use in horn-loaded, as well as bass-reflex compact enclosures. Its cone is capable of carrying significant loadings thanks to a dedicated reinforcing treatment.
The extremely powerful external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The levels of force factor and power handling result in the best power to weight ratio on the market today..
The curvilinear paper cone has been designed by Eighteen Sound engineers with a special high-strength wood pulp to achieve the best possible linearity within its intended frequency range and to control bell-mode resonances around the cone circumference. The cone is carried by a multiroll suspension built from a linen-like material, which is more resistant to aging and fatigue than traditional materials. The basket, heat sink and cone singular treatments make the 12ND610 suitable for use in high humidity environments.
The 75 mm state-of-the-art voice coil is similar to the one fitted to our top-of-the-range 18" and 15" models but it is wound with aluminum wire. It employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil.

The 12ND830 is a scaled-down version of our 15ND830 and differs from the 12ND930 in the wire conception, offering a lighter speaker with a lower force factor.
The 12ND830 finds its ideal application in compact reflex enclosures where a considerable amount of low frequencies and low distortion are required. Its optimum low weight makes it suitable for fixed installations or portable professional loudspeaker systems.
The neodymium magnet assembly developed by Eighteen Sound engineers assures a high flux concentration, low power compression and excellent heat exchange since the external magnet configuration is considerably more efficient than traditional under-pole magnet topology.
The direct contact between the large heat sink and the specially designed basket, together with the magnetic structure, represents a fundamental improvement in thermal connection and heat dissipation. The result is increased power handling capabilities and lower power compression.

The 12ND930 is a high power, high output, low frequency woofer meeting the most stringent requirements in high quality professional transducers. The high level of performance and sound quality have been achieved by exploiting the most advanced technologies available today.
Thanks to its versatility, the 12ND930 transducer can be used in two-way compact reflex enclosures with a 1.4" compression driver, in multi-way systems and in high loading sub woofers as small as 50 lt (compact reflex, band-pass and hornloaded configurations).
The neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange, since the external magnet configuration is considerably more efficient than traditional under-pole magnet topology.
This results in high levels of force factor and power handling with an optimum power to weight ratio. The direct contact between the large heat sink and the basket, together with the magnetic structure, represents a fundamental improvement in thermal connection and heat dissipation. The result is increased power handling capabilities and lower power compression.
The curvilinear cone profile, created with a special high strength wood pulp, has been designed to achieve the best possible linearity within its frequency range. The cone surround in linen material is highly resistant to aging and fatigue. The in-house developed cone treatment is a humidity repellent and significant dampens bell mode resonance.
The 12ND930 employs our Interleaved Sandwich Voice coil (ISV) in which a high strength fiberfiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. The final result is an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
The already low distortion and sound quality are further improved by Double Demodulating Rings (DDR) that flaten impedance and phase with a constant power transfer.
A special coating applied to both the top and back plates makes the 12ND930 far more resistant to the corrosive effects of salts and oxidization.

The 12W500 is a fine example of a high quality transducer providing the right balance between performance and engineering costs.
The 12W500 is a 500W program low frequency driver designed to satisfy the need for a 12" loudspeaker which combines excellent linearity with good sensitivity and power handling characteristics. It is primarily intended for compact bass reflex applications in enclosures as small as 50 lt, typically for two-way systems in combination with 1� compression driver.
The high quality paper cone has a smooth, curvilinear profile design that eliminates bell-mode resonances within the intended frequency range. This is carried by a specially treated, dampened double half-roll linen suspension which has been designed to control excursion maintaining the piston action linearity.
The 12W500 employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
Voice coil cooling is achieved by incorporating airways between the chassis back plate and the top plate of the magnet, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. This technology is another result of the 3D CAD resource application by our engineers.

The 12W700 meets the specific market requirement for a loudspeaker which combines the excellent linearity, good efficiency and high power handling of the 15W700 model but in a 12" chassis for use in more compact systems. It is primarily intended for application in compact reflex and band-pass enclosures but can also be used for horn loaded configurations. The ribbed curvilinear paper cone has been made from a special high strength woodpulp designed to achieve the best possible linearity within its intended frequency range and to control bell-mode resonances around the cone circumference. The cone is carried by an unusually deep profile, triple roll suspension made from a polycotton material which is more resistant to aging and fatigue than traditional cotton-based ones.
The 75 mm � state-of-the-art voice coil is similar to that fitted to our top-of-the-range 18" and 15" models. It employs our Interleaved Sandwich Voice coil (ISV) in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
The magnetic structure has been optimized using our in-house FEACAD resource to maximize the flux density in the voice coil gap.
Voice coil cooling has been achieved by incorporating airways between the chassis back plate and the top plate of the magnet, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. The basket itself is the result of a meticulous design exercise using the sophisticated 3D CAD resource within the Eighteen Sound R&D facility.
Due to the increasing use of audio systems at outdoor events, the ability to perform in adverse weather conditions or in high-humidity areas is an essential feature of our 12W700. This has been achieved using an exclusive cone and magnet plate treatment process which increases resistance to corrosion and renders the cone water repellent.

The 12MB700 is the result of extensive research carried out in our R&D and Engineering Departments which aimed to produce a very high sensitivity (101.5 dB 1W/1m) midbass driver with high power handling capabilities. The 12MB700 can be used as either a bass/mid driver in compact 2-way reflex enclosures or as a direct radiating or horn loaded, dedicated midrange driver, in multi-way touring and fixed installation concert and arena systems.
Its curvilinear paper cone made from a special high strength wood pulp, has been designed to achieve the best possible linearity within its intended frequency range and to control bell-mode resonances around the cone circumference. The cone is carried by a multiroll suspension formed of a linen-like material, which is more resistant to aging and fatigue than traditional materials.

This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.

The 12LW1400 is a low frequency loudspeaker which sets a new industry standard in 12" (300 mm) 4" voice coil high performance transducers, already accomplished by the 15LW1400 and 18LW1400 respectively.
It has been designed for use as a subwoofer or low frequency component in multi-way systems where considerable amounts of power and low distortion are needed. It is ideally suited for very high loading situations, such as bandpass, horn loaded or compact reflex configurations. In its reflex configuration, it can be used in extremely compact enclosures (30 - 60 lt), making the 12LW1400 ideally suited for touring applications, sound reinforcement or fixed installations, including indoor and outdoor concert reinforcement systems.
Maximum strength, smooth response and high displacement piston motion are obtained using Double Silicon Spider technology (DSS) and a large excursion surround. A special formulation cone material has been used to enable it to withstand high loading and high power peaks. The suspension system has been designed to give symmetric large signal behavior across the whole working range, providing low harmonic distortion at different excitation levels.
A new state-of-the-art voice coil, based on Interleaved Sandwich Voice coil (ISV) provides high levels of thermal stability and durability. The ISV technology is based on a high strength fiberglas former with half the coil wound on the outside and half on the inside ensuring uniform thermal dissipation on both sides. It is bonded together using unique high temperature resin adhesive to achieve a balanced and solid linear motor unit.
Great care has been taken to symmetrize all non linear characteristics, mechanical as well as electromagnetic. Customized Double Demodulation Rings technology (DDR) has also been used to further improve the performance of this speaker. This technology dramatically reduces the intermodulation and harmonic distortion whilst improving the transient response.
The top plate and back plate design have been optimized for cone excursion and maximum symmetric force factor by the use of in-house FEA Magnetic simulation software.
Furthermore, excellent heat dissipation has been achieved by the special basket design which incorporates air channels between the basket and magnetic top plate.
The speaker is able to perform properly under inclement weather conditions due to an exclusive cone treatment which improves pulp strength and gives water repellent properties to both sides of the cone. In addition, the special treatment of both the top and back plates makes them far more resistant to the corrosive effects of salts and oxidization. This treatment is far more effective than any other treatment in use today.

The 12LW800 is a low frequency loudspeaker which sets a new industry standard in 12" (300mm) � high performance transducers, achieving a remarkable 42Hz downwards extension with 96dB average sensitivity and handling peak power levels of 4000W with remarkably low distortion and excellent transient response.
The 12LW800 is intended as the low bass or sub-woofer component, either in highly compact reflex, bandpass or horn loaded configurations, in which it provides clean, linear frequency reproduction at high power levels, or as part of a compact high power fullrange system. In its reflex configuration, it can be used in extremely compact enclosures (40 - 70lt) making it ideal for portable applications such as road shows and bass musical instruments, for �wedge� stage monitors, etc.
The high excursion capabilities of the double-action roll surround and suspension system, in conjunction with the Eighteen Sound Double Silicon Spider (DSS), enable the 12LW800 to achieve very high levels of linear travel for a 12" unit.
With its custom design surround, the carbon fiber reinforced curvilinear ribbed cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress.
The 75 mm state-of-the-art voice coil is similar to that of our 18LW1400 top-of-the-range model. It employs our Interleaved Sandwich Voice coil (ISV) in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil and providing a uniform motive drive. This, in conjunction with the use of unique high temperature resin adhesives, results in an extremely linear motor assembly with reduced tendency to break-up under hard drive conditions.
Excellent heat dissipation is achieved incorporating air channels between the basket and the top plate.
Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the face and back plates, which have been designed using our in-house Magnetic Flux FEA CAD resource.
With the increasing use of high power audio systems at outdoor events or in marine environments, the ability to perform properly under inclement weather conditions is an essential point of the Eighteen Sound philosophy. These features are obtained through an exclusive cone treatment improving pulp strength and giving water repellent properties to the cone. In addition, a special treatment applied to both the face and back plates allows the product to be far more resistant to the corrosive effects of salts and oxidization than any other treatment in use.

The 12MB1000 is our flagship 12" ferrite midrange driver. It offers high power handling capability with exceptional sensitivity over the middle frequency band. It can be used with either direct radiating or horn loaded applications, as well as part of a 2 or 3-way system. It is ideally used in stage monitor, auditorium, touring and outdoor systems. The 12MB1000 is the result of an intensive development program which aimed to produce the best 12" midrange driver possible.
The smooth curvilinear paper cone has a special high strength wood pulp composition designed to achieve the best possible linearity within the middle frequency range and to control bell-mode resonances around the cone. The cone is carried by a double half-roll suspension, which is more resistant to aging and fatigue than traditional materials, and provides the correct dampening and excursion control.
The state-of-the-art voice coil employs our own Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces. By mean of a balanced coil with uniform distribution of mass and motive energy, this technology assures an extremely linear motor assembly.
The voice coil cooling has been achieved by incorporating airways between the chassis back plate and the top plate of the magnet which allow heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. This technology is the result of a meticulous design exercise using a sophisticated in-house 3D CAD facility. The magnetic structure has also been optimized using our in-house FEA CAD resource to maximize flux density in the voice coil gap.
Eighteen Sound R&D has developed a special cone treatment designed to improve the dampening properties of the moving assembly, thus considerably improving the transient response control. This treatment also gives water repellent properties to the cone, enabling the12MB1000 to be used in humid environments without damage.
