Description
The 18LW2400 is the evolution of our industry standard 18LW1400 subwoofer. It is an extended low frequency loudspeaker designed for use as a low bass or subwoofer component, in either a reflex, bandpass or horn loaded configuration. The loudspeaker can directly retrofit 18LW1400 without cabinet modifications, while providing higher maximum SPL, increased program power handling and lower power compression. For optimum results we recommend amplifiers able to deliver 2400 Watt program power without clipping.
Transducer design features include a large displacement suspension system which, in conjunction with a fiberglass reinforced, straight ribbed cone and the Eighteen Sound proprietary Triple Silicon Spider (TSS) technology, allows an ultra-linear piston action and provides full mechanical control across the entire working range.
The 100 mm (4 in) inside-outside copper voice coil based on Interleaved Sandwich Voice coil (ISV) technology provides high levels of thermal stability and durability.
In order to furtherly increase power handling and reduce power compression figure, 18LW2400 uses the same voice coil ventilation technology developed for our flagship 9000 neodymium transducer series. A special low density material air diffractor has been placed into the backplate acting as a cooling system, increasing power handling capability and lowering the power compression figure. As a final result Eighteen Sound engineers obtained almost 1 dB reduction in full power power compression value if compared to 18LW1400, and an increased program power handling value of 2400 Watt.
The low distortion and unmatched sound quality of the 18LW2400 has been significantly improved by Double Demodulating Rings (DDR) embedded in the pole piece of the magnetic structure. These have been designed to reduce the intermodulation and harmonic distortion while improving the transient response.
10% reduction in weight have been obtained optimizing the magnetic structure through advanced FEA CAD simulation tools.
18LW2400 is able to perform properly under inclement weather conditions: the exclusive cone treatment improves pulp strength and gives water repellent properties to both sides of the cone. In addition, the special treatment applied to top and back plates of the magnetic structure is far more resistant to the corrosive effects of salts and oxidization.

The 18ND9300 is an extended low frequency loudspeaker which sets a new industry standard in 18" (460 mm) neodymium high performance transducers. The speaker has been derived from our flagship 18LW1400, after in-depth studies on magnetic circuit design, which focused on dissipating the heat generated by the powerful 4" coil.
The loudspeaker design provides clean and undistorted LF reproduction at a very high SPL and enables the speaker to withstand high power levels without damage.
The neo magnet assembly assures high flux concentration, low power compression and excellent heat exchange. 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 heatsink has been specifically studied using F.E.A. simulators and the necessary heat transfer to the dissipative structure has been improved. The heat sink 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 specially designed basket, together with the magnetic structure, represents a fundamental improvement in heat dissipation, increasing power handling capabilities and lowering power compression figure.
18ND9300 design features include an exceptional displacement suspension system which, in conjunction with a carbon fibre reinforced, straight ribbed cone and a Double Silicon Spider (DSS), result in an ultra-linear piston action, providing full control across the entire working range.
The state-of-the-art voice coil, based on Interleaved Sandwich Voice coil (ISV) technology, provides high levels of thermal stability and durability. The ISV technology achieves a balanced linear motor unit exerting an exceptionally high force factor. This is realised through a high strength fiberglas former with half the coil wound half on the outside and half on the inside and bonded together using unique high-temperature resin adhesives.
The low distortion and unmatched sound quality of the 18ND9300 have been further improved by Double Demodulating Rings (DDR) embedded in the pole piece of the magnetic structure.
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 18ND9300 far more resistant to the corrosive effects of salts and oxidization.

The 18W1000 is a low frequency woofer which sets a new industry standard in 18" (460 mm) high output transducers. It represents a further development of the Eighteen Sound 18LW1250 but has a lighter mass and increased sensitivity.
The 18W1000 can be used as a low bass or sub-woofer component, in either a reflex, bandpass or horn loaded configuration, in high power fixed or touring loudspeaker systems. It provides clean, linear, undistorted low frequency reproduction at very high power levels.
The high excursion capabilities of the surround and suspension system, in conjunction with the Double Silicon Spider (DSS), enables the 18W1000 to achieve high levels of linear travel while maintaining full control of the moving mass.
The high quality curvilinear cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress.
The state-of-the-art voice coil 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 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 magnetic top plate.
Maximum flux concentration and force factor in the gap is assured by the unique shape and design of the top and back plates, which have been researched and designed using our in-house magnetic flux FEA CAD resource.
Due to the increasing use of audio systems at outdoor events, the ability of the 18W1000 to perform in adverse weather conditions or in areas of high humidity is a key feature. This has been achieved using an exclusive cone treatment and magnetic plate processes which resist corrosion and render the cone water repellent.

Its design features include a large displacement suspension system which, in conjunction with a carbon fiber reinforced, straight ribbed cone and the Eighteen Sound Double Silicon Spider (DSS), assure an ultra-linear piston action and provide full control across the entire working range.
A new state-of-the-art voice coil based on Eighteen Sound�s Interleaved Sandwich Voice coil (ISV) increases this control, providing high levels of thermal stability and durability. This ISV technology is based on a high strength fiberglas former with half the coil wound on the outside and half on the inside and bonded together using unique high temperature resin adhesives. Hence, a balanced linear motor unit, exerting an exceptionally high force factor is achieved. The low distortion and unmatched sound quality of the 18LW1400 has been significantly improved by the Double Demodulating Rings (DDR) embedded in the pole piece of the magnetic structure. These have been designed to dramatically reduce the intermodulation and harmonic distortion while improving the transient response.
Excellent heat dissipation has been achieved from the special basket design which incorporates air channels between the basket and the magnetic top plate. In addition, 8 air vents incorporated into the back plate are aligned with the voice coil to force air into the lower part of the gap.
Maximum flux density in the gap is assured by the special top and back plate design, resulting in a high BL factor.
Due to the increasing use of high power audio systems at outdoor events or in marine environments, the ability of the 18LW1400 to perform properly under inclement weather conditions is a great advantage. This has been achieved using an exclusive cone treatment that improves pulp strength and gives water repellent properties to both sides of the cone. In addition, the special treatment applied to top and back plates of the magnetic structure is far more resistant to the corrosive effects of salts and oxidization than any other treatment in use.
