Peerless SLS-P830945 5-1/4″ Paper Cone Woofer 4 Ohm

A new addition to the SLS Series of speakers, the Peerless SLS-P830945 5-1/4″ subwoofer features a paper cone, wide rubber half-roll surround, and hefty ceramic ferrite magnet with distortion-reducing aluminum shorting ring. This driver will provide accurate and detailed low frequency audio reproduction.

The speaker’s distinctively sculpted truncated steel frame facilitates close driver spacing or a narrower mounting baffle, and its extensive under-spider venting promotes voice coil cooling for reduced power compression and improved long term reliability. The P830945 will perform superbly as a dedicated low-mid bass driver, as well as delivering solid output when used as a compact subwoofer.
