Eighteen Sound 15NLW4500 8-Ohm 15" Subwoofer 3000 Watts Low Frequency LoudSpeaker

Eighteen Sound 15NLW4500 8-Ohm 15" Subwoofer 3000 Watts Low Frequency LoudSpeaker

Features

• 115mm (4.5in) Interleaved Sandwich Voice coil (ISV)

• Weather protected cone and plates

• Great heat dissipation capability

• Ultra linear suspension system

• Neo motor for high power and very efficient thermal exchange

• Single demodulating ring (SDR) for distortion reduction and maximum SPL

The 15NLW4500 is a 15" extended low frequency loudspeaker, designed for use in vented, bandpass or even horn loaded ì enclosures. The loudspeaker is designed to withstand high power levels without damage while providing clean and undistorted LF reproduction at a very high SPL. For optimum results we recommend amplifiers able to deliver 3000 Watt program power.

The 15NLW4500 features a unique motor featuring a high grade Neo magnet assembly in a structure optimized for thermal and magnetic efficiency. 15NLW4500 features include a large displacement suspension system which, in conjunction with a composite reinforced, straight ribbed cone and the Eighteen Sound proprietary SDR technology, allows an undiostorted ultra-linear piston action and provides full mechanical control across the entire working range.

The 115mm (4.5 in) state-of-the-art voice-coil utilizing 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.
