Pioneer

Pioneer's TS-W311D4 12" subwoofer is built to take it as well as dishing it out. This Pioneer Champion Series sub features a ribbed cone that's injection-molded for exceptional precision and strength. A double-layered elastic polymer surround supports the woofer during cone excursion so you'll get accurate, hard-hitting bass notes even when the music's turned up loud. The dual 4-ohm voice coils allow you to wire the sub for 2- or 8-ohm impedance, so you get the flexibility you need to add more Champion Series subs in the future. If your vehicle's audio system sounding a little thin, this Pioneer sub can remedy that situation, bringing out all the punch and power in your music by filling in the lowest frequencies of the sound spectrum. Throw one or two of these subs in your daily ride, power them up with a nice amp, and you'll understand what the fuss is all about — whatever you listen to, great bass will make it sound much, much better.
