Peavey 1808-8 SPS BWX Description

The Peavey 1808-8 SPS BWX is engineered for high-demand low-end reproduction, making it a top choice for replacement or custom-built subwoofer and bass cabinet designs. The Kevlar®-impregnated cone delivers increased stiffness and resistance to deformation under heavy loads, while the 4-inch voice coil on a polyimide-impregnated fiberglass former allows for sustained high power operation.

This model is optimized for use within the frequency range of 35 Hz to 1 kHz, making it highly suitable for sub-bass and kick drum reinforcement. Its efficiency is further enhanced by a strong BL factor of 16.26 T/M and a moving mass of 106.7 grams, delivering both punch and precision. Whether in live PA systems or permanent installs, the 1808-8 SPS BWX delivers robust and clear low-frequency performance with reliable thermal and mechanical handling.
