Eighteen Sound 15NLW4500 8 Ohm 15″ 1500W Loudspeaker

Product description:

The Eighteen Sound 15NLW4500 is a 15″ extended low frequency loudspeaker, designed for use in vented, bandpass, scoop or horn loaded loudspeaker designs.

The 15NLW4500 is designed to withstand high power levels whilst providing clean and undistorted Low Frequency reproduction at a very high SPL.

18 Sound recommend amplifiers able to deliver 3000 Watt program power for optimum results.

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 that in conjunction with a composite reinforced, straight ribbed cone and the Eighteen Sound proprietary SDR technology, allows an undistorted ultra-linear piston action providing full mechanical control across the entire working range.
