Product Description

The Pioneer TS-D12D4 was built to handle up to 600 watts RMS, while it dishes out impressive low-frequency punch. This sub features an injection-molded polypropylene cone that’s impregnated with Aramid fibers for exceptional precision and strength. A butyl rubber 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 sub’s dual 4-ohm voice coils give you more wiring options when setting up your system.

Add some boom to your daily drive

If your vehicle’s audio system is sounding a little thin, this potent Pioneer TS-D12D4 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.


Too much isn’t enough, embrace the bass. The D subwoofer is a culmination of Pioneer technologies that produce thick, deep, powerful and accurate bass that makes listening to your favorite music energetic, fun and engaging.
Combining bass quality and bass quantity with high power, plus installation flexibility that provide high performance in both acoustic suspension (sealed) and bass reflex (ported) enclosures, the Pioneer TS-D12D4 subwoofer is the ultimate all-around performer.Slam, attack, power. Don’t just listen to your music, feel it.


Made of a specially blended, highly durable and moisture-resistant compound, butyl rubber keeps the cone moving in a linear direction, seals the cone to the basket and quickly dampens cone vibration once the signal has changed or stopped. This results in less distortion and superior frequency response.


Polypropylene (PP) is a tough thermoplastic resin that is an ideal material for the Pioneer TS-D12D4 subwoofer cone – with low mass and high damping, PP cones offer good sensitivity and low distortion. However, polypropylene cones lack the rigidity and strength required for high output and extreme low bass. To resolve this, Pioneer engineers used advanced Computer-Aided Manufacturing to develop a process to blend aramid fibers into the polypropylene resin during the injection molding process. The resulting Aramid Fiber Interlaced IMPP subwoofer cone is incredibly strong and low mass with high rigidity and superior strength to produce deep, powerful and undistorted bass.


A subwoofer motor structure consists of the voice coil and magnet assembly. Increasing the diameter and length of the voice coil provides greater control of the woofer cone and higher power handling. To take full advantage, however, the magnet must also be increased, both in magnetic power and physical size. The D subwoofer uses an oversized 4-layer voice coil and high energy double stacked magnets to increase the overall power handling and SPL output with no sacrifice in sound quality.
