Pioneer TS-W307D4 Car Speaker

TS-W307D4 provides two voice coils, so you can use a low-impedance amp to produce much bigger, much more powerful bass. More options, more power. It offers you a variety of set-up possibilities, provided that there is correct power matching between the subwoofer and your amplifier. So, whether you are building your system from an existing stereo or mono amp, or whether you want a basic set-up with expandability potential, the TS-W307D4 will cover common impedance loads. The IMPP (Injection Moulded Polypropylene) cone is constructed from a composite blend of interlaced Aramid fibers, which make it extremely rigid; yet lightweight, for low distortion and powerful bass at high sound press levels. The speaker terminals have been placed on one side of the subwoofer, rather than on both sides as with conventional subs; this gives you greater installation flexibility. The TS-W307D4 is for enclosed use.
