The 15NW530 low frequency neodymium transducer has been specifically developed for high power, low distortion, compact subwoofer applications.
The transducer finds its main application on compact vented subwoofers as small as 75 lit. properly tuned, but it is suitable also in bandpass or horn loaded applications.
The high level of performance and sound quality have been achieved using the most advanced technologies available today in terms of distortion reduction.
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 transducer incorporates Eighteen Sound exclusive DSS technology (Double Silicon Spider) in combination with a single roll highly damped rubber surround.
The already low distortion and sound quality are further improved by properly positioned Single Demodulating Ring (SDR technology) that flatten impedance and phase with a constant power transfer.
The 75mm edge-wound state-of-the-art voice coil assembly is wound on a strong fiberglas former to improve force transmission and power handling.
The deep profile curvilinear cone, created from a special high strength wood pulp, has been designed to achieve the best possible linearity within its frequency range. The in-house developed cone treatment is a humidity repellent and significantly dampens bell mode resonances.
A special coating applied to both the top and back plates makes the 15NW530 far more resistant to the corrosive effects of salts and oxidization.

The 15NLW9300 is an extended low frequency loudspeaker which sets a new industry standard in 15" (380mm) neodymium 4" voice coil high performance transducers. The design has evolved from an extensive R&D program carried out at Eighteen Sound, providing clean, undistorted LF reproduction at very high SPL without damages.
The 15NLW9300 is intended mainly as woofer for studio monitoring or multiway systems applications in extremely compact vented enclosures (65-130lit). This make it ideal for touring application including indoor or outdoor concert reinforcement systems. Thanks to improved speaker design specifications and use of high grade materials it is the ideal transducer for touring applications or fixed installations.
The neo magnet assembly assures high flux concentration, low power compression and excellent heat exchange, resulting in high levels of force factor and power handling with an optimum power to weight ratio.
The heatsink has been specifically studied using F.E.A. simulators and the necessary heat transfer to the dissipative structure has been improved. The direct contact between the heatsink and the basket represents a fundamental improvement in heat dissipation, increasing power handling capabilities and lowering the power compression figure.
The 15NLW9300 features a dedicated exclusive carbon fibre reinforced straight ribbed cone, with a specific pulp formulation containing damping fibres. The membrane is then treated in-house with a proprietary resin mix in order to increase the cone bend performances, up to 6 times better if compared with traditional celluloses pulp, twice than glass fibre added pulps. The results is a very linear piston action across the entire working range avoiding the destroying breaking modes. The cone treatment make the 15NLW9300 suitable for outdoor application.
The suspension system has been designed to provide symmetric large signal behaviour throughout the whole working range, providing low harmonic distortion at different excitation levels.
The performances are further improved by the proprietary Double Demodulating Rings technology (DDR), designed to reduce dramatically the intermodulation and harmonic distortion whilst improving the transient response.
The state-of-the-art 100mm (4in) Interleaved Sandwich Voice coil (ISV) provides high levels of thermal stability and durability.

The 15NMB420 is a 15" midbass transducer designed for professional monitoring and sound reinforcement. At the heart of this speaker is a carefully engineered drive system. Its design assures 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 15NMB420 at these frequencies is much reduced compared to sealed enclosures, directly reducing harmonic distortion and the possibility of speaker bottoming. Typical enclosure sizes range from 80lit. up with tunings from 40 to 50Hz; low-frequency equalization is suggested and normally added in order to improve the bass output. Speaker applications are from subwoofers to 2 way systems. A conservative idea of amplifier size ranges from 400-800W. Amplifiers of this size will allow maximum output with minimal risk of speaker damage when properly used.
Incorporated into the design is the SDR(Single Demodulating Ring), used to reproduce instantaneous peak 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 of the category.
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 15NMB420 employs a 75mm 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.
A proprietary humidity-block cone treatment has been implemented in order to perform in outdoor environments under adverse weather conditions. In addition, special treatment of both the face and back plates results in a product which is far more resistant to the corrosive effects of salts and oxidization than any other treatment in use.

The 15NLW9500 is an extended low frequency loudspeaker which sets a new industry standard in 15" (380mm) neodymium 4" voice coil high performance transducers. The 15NLW9500 is derived from our flagship 15LW1500, after in-depth studies on magnetic circuit design which focused on dissipating the heat generated by the powerful 4" voice coil. Extensive care has been taken in order to symmetries both mechanical and electromagnetic non linear behaviour. The 15NLW9500 has been designed to cover the low frequency band in vented, bandpass and horn loaded configurations. Thanks to improved speaker design and the use of high grade materials, its applications range from studio monitors up to cinema subwoofers as well as professional sound reinforcing systems, where deep low frequencies are required. The 15NLW9500 has remarkable 35Hz downwards extension with 96dB average sensitivity and achievable peak power levels of 7kW. It can be used in enclosures from 90 liters in size upwards, with tuning frequencies of about 33Hz. It requires low frequency equalization in small enclosures, while bigger volumes require slightly less equalization for a similar output. Amplifier sizes of 700 to 1400W allow a maximum output from the loudspeaker with minimal risks when properly used.
The neo magnet assembly assures high flux concentration, low power compression and excellent heat exchange. In fact, the external magnet configuration is considerably more efficient than the traditional under-pole magnet topology. This results in high levels of force factor and power handling with an optimum power to weight ratio. The heatsink has been specifically studied using F.E.A. simulators and the necessary heat transfer to the dissipative structure has been improved. The heatsink concept has been further improved by using an air-diffractor that offers high thermal capacity and has been designed to force air moved by the dust cap through the heat sink fins and cool it down. The direct contact between the heat sink and the basket, together with the magnetic structure, represents a fundamental improvement in heat dissipation, increasing power handling capabilities and lowering the power compression figure.
The carbon fiber reinforced, straight-sided ribbed cone has been adopted in order to enable the transducer to withstand high loading designs as well as high power peaks.
Maximum strength, smooth response and high displacement piston motion have been obtained using Double Silicon Spider technology (DSS) and a large excursion surround.
The rubber suspension system has been designed to provide symmetric large signal behaviour throughout the whole working range, providing low harmonic distortion at different excitation levels.

The 15MB606 high output mid bass has been designed for use as a bass and low-midrange driver in tuned reflex enclosures, in 2-way systems. It combines high sensitivity (101dB 1W/1m) with high power handling capability, at a good price for a 75 mm voice coil device.
The smooth textured curvilinear paper cone, in conjunction with the viscose dampened multiroll suspension, provides excellent cone dampening and excursion control.
The 75 mm � state-of-the-art voice coil features the same technology fitted to our top-of-the-range 4� voice coil models. It employs our Interleaved Sandwich Voice coil (ISV), in which a high strength fiberglas former carries windings on 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 low inductance coil results in improved transient response.
Excellent heat dissipation has been achieved by incorporating air channels in the basket design, between the basket and top plate. Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the top and back plates, which was created using our in-house Magnetic Flux FEA CAD resource.
A special treatment is applied to the top and the back plate which increases their resistance to the corrosive effects of salts and oxidization. This treatment is more effective than any other treatment in use today.

The 15W500 is a fine example of a high quality transducer providing the right balance between performance and engineering costs. This ferrite low frequency driver satisfies the demand for a 15" loudspeaker which combines excellent linearity with good sensitivity and power handling characteristics.
The 15W500 has been designed for two-way or multi-way reflex systems. When used in a two-way system, we recommend a 1.4" or 2" exit HF compression driver match for the best sound quality results.
The high quality paper cone has a smooth, Eighteen Sound specified curvilinear profile design that eliminates bell-mode resonance within the intended frequency range. The cone is carried by a specially treated and dampened double half-roll linen suspension designed to control excursion while maintaining piston action linearity.
The 15W500 also 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 has been achieved by incorporating airways between the chassis back plate and the magnetic top plate, allowing 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 3D CAD design project.

The 15W700 low frequency transducer meets the specific market demand for a loudspeaker which combines good linearity and efficiency with high power handling capabilities, containing a 75 mm � voice coil. Although primarily intended for use in tuned reflex enclosures, the versatile characteristics of the 15W700 render it suitable for a wide variety of enclosure types, particularly as a subwoofer or as a LF driver in 2 or 3-way systems. When used in a 2-way system, we recommend a 1.4" or 2" exit compression driver in order to obtain the best sound quality.
The deep profile curvilinear paper cone has been made using a special high strength wood pulp and 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, double half-roll suspension formed of a linen-like material which is more resistant to aging and fatigue than the traditional cotton-based materials used in conventional surrounds.
The 75 mm � state-of-the-art voice coil is the same as those fitted to our top-of-the-range 18" and 15" models. It employs our Interleaved Sandwich Voice coil (ISV) system, 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 FEA CAD resource that has maximized the flux density in the voice coil gap. Excellent heat dissipation has also been achieved by incorporating air channels between the basket and the magnetic top plate.
Due to the increase in use of audio systems at outdoor events, the ability of the 15W700 to perform in adverse weather conditions or in areas of high humidity is a great advantage. This has been achieved using exclusive treatments which enable the cone and the magnetic plate to resist corrosion and render the cone water repellent at the same time.

The 15MB1000 is a mid-low frequency transducer which has been created to meet requirements for low bass applications where a significant extension in mid frequency is needed. It has been designed for use in compact reflex enclosures, in 2-way systems with 1.4" - 2" compression drivers and stage monitoring applications. 15MB1000 is also suitable for horn loaded applications in multiway systems.
The low profile, carbon fiber reinforced, smooth curvilinear cone provides smooth response within its intended frequency range and exceptional strength with maximum reliability under high mechanical stress.
The copper shorting ring on the plates has been adopted to reduce inductance and improve transient response. Intermodulation distortion has also been significantly improved.
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 to achieve a balanced coil with a uniform distribution of mass and motive energy. This results in an extremely linear motor assembly.
Excellent heat dissipation has been achieved by incorporating air channels between the basket and the magnetic top plate. Further ventilation is provided using air vents in the back plate that direct air into the lower part of the voice coil gap.
Considerable attention has also been given to the design of the magnetic structure in order to maximize flux concentration and force factor in the gap.
Due to the increasing use of high power audio systems at outdoor events, the ability to perform in adverse weather conditions is a key feature of the 15MB1000.

The 15LW1500 is a low frequency loudspeaker which sets a new industry standard in 15" (380 mm) high performance transducers, achieving a remarkable 34 Hz downwards extension with 96 dB average sensitivity and handling peak power levels of 7000 W.
The 15LW1500 has been designed for use as a low bass or subwoofer component in either highly compact reflex, bandpass or horn loaded configurations. It provides clean, linear frequency reproduction at high power levels, as part of a compact high power fullrange system. In its reflex configuration, it can be used in extremely compact enclosures (75 lt) making it also suitable for portable applications, such as, road shows and bass musical instruments.
The low noise and high excursion capabilities of the double-action roll surround and suspension system, in conjunction with the Eighteen Sound Double Silicon Spider (DSS), enable the 15LW1500 to achieve very high levels of linear travel for a 15" unit.
The already low distortion and unmistakable sound quality of this loudspeaker is further improved using Double Demodulating Rings (DDR) designed to dramatically reduce the intermodulation and harmonic distortion while improving the transient response.
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 to achieve a balanced coil with a uniform distribution of mass and motive energy that results in an extremely linear motor assembly.
The carbon fiber reinforced straight ribbed cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress.
Excellent heat dissipation has been achieved by incorporating air channels between the basket and top plate of the magnet. Further ventilation is provided using air vents in the back plate to direct air into the lower part of the voice coil gap.
Due to the increase in use of high power audio systems at outdoor events or in marine environments, the ability to perform properly under inclement weather conditions is a key feature in the Eighteen Sound philosophy. This has been achieved thanks to an exclusive cone treatment improving pulp strength which gives water repellent properties to both sides of the cone. In addition, a special treatment is applied to the top and back plates which is far more resistant to the corrosive effects of salts and oxidization than any other treatment in use today.

The 15LW1401 is a low frequency loudspeaker which sets a new industry standard in 15" (380 mm) high performance transducers, representing a further development of the 15LW1400 but with a higher travel. The 15LW1401 achieves a higher maximum SPL at low frequencies with reduced THD.
It has been designed for use as a low bass or sub-woofer component in either a more compact reflex, bandpass or horn loaded configuration. It provides clean, linear, undistorted low frequency reproduction at very high power levels, as part of a high power fullrange system. In its reflex configuration, it can be used in extremely compact enclosures, (65 - 130 lt) which is ideal for touring applications, including indoor and outdoor concert reinforcement systems.
The high excursion capabilities of the surround and suspension system, in conjunction with the Eighteen Sound Double Silicon Spider (DSS), enable the 15LW1401 to achieve high levels of linear travel and maintain full control of the moving mass. The carbon fiber reinforced, straight-sided ribbed cone assures smooth response and exceptional strength, with maximum reliability under high mechanical stress.
The 100 mm � state-of-the-art voice coil is the same fitted to the 18LW1400. 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 weight of the windings are evenly distributed, providing a uniform motive drive. This, in conjunction with the use of state-of-the-art high temperature resin adhesives, results in an extremely linear motor assembly.
The already low distortion and sound quality of this loudspeaker has been further improved by the Double Demodulation Rings (DDR) designed to dramatically reduce the intermodulation and harmonic distortion whilst improving the transient response.
Excellent heat dissipation has been achieved by incorporating air channels between the basket and the top plate of the magnet. Further ventilation is provided using air vents in the back plate that direct air into the lower part of the voice coil gap.
Maximum flux concentration and force factor is assured by the unique shape and design of the top and back plates, researched and designed using our in-house Magnetic Flux FEA CAD resource.
The 15LW1401�s ability to perform properly under inclement weather conditions has been achieved using an exclusive cone treatment improving pulp strength which gives water repellent properties to both sides of the cone. In addition, a special treatment has been applied to both the top and back plates that is far more resistant to the corrosive effects of salts and oxidization than any other in use today.
