Product Details

Pioneer TS-W304R 12" 1300W Mobile Audio Subwoofer 4 Ohm

Pioneer's TS-W304R subwoofer features an all-new design and look. All areas of performance have been increased over Pioneer's prior generation of subwoofers. Its six-layer voice coil allows for 300 watts RMS power handling (1,300 watts max) to really get things cranking on your daily commute. Purpose-built to work well in sealed and ported enclosures. A large Strontium magnet create a high power motor assembly for a high sensitivity of 95 dB @ 1W/1m,.

IMPP Composite Seamless Cone

An extremely durable, yet lightweight cone is vital to prevent a cone failure at high sound pressure levels. Pioneer's new IMPP composite seamless cone meets this need perfectly while delivering accurate yet powerful bass and increasing sensitivity.

Treated Foam Surround

The treated foam surround dramatically improves durability and lightness for superior response, especially at louder volumes. It also prevents against fatigue created by the extreme temperature swings present in car audio environments. 

Vented Pole Piece

Pioneer designed the TS-W304R with a vented pole piece to promote movement of air within the subwoofer. The vent is smoothly channeled for optimal ventilation to ensure a quick response and clear reproduction of bass, reducing the compression that results from trapped air during heavy bass passages. 

Includes six 1-1/8" self-tapping screws.

Pioneer TS-W304R 12" 1300W Mobile Audio Subwoofer 4 Ohm
Pioneer TS-W304R 12" 1300W Mobile Audio Subwoofer 4 Ohm is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Sensitivity Value Is WrongI bought this driver and measured it with my Dayton Audion Woofer Tester. The actual sensitivity is only about 88 dB @ 1W/1m. I checked the measurement by calculating the theoretical sensitivity using Bass Box 6 with the listed nominal parameters, and got about the same number. I contacted Pioneer's customer service to complain about the discrepancy, and their engineers informed me that the 95 dB listed is an in-car measurement, not @ 1W/1m. Even their website, to date, still lists the sensitivity at 1W/1m. In retrospect, I should have run the numbers myself before buying it, but the manufacturer's site listed the same number, so I believed it. Won't happen again.

Would this sub make a suitable home theatre sub?  I know that it is essentially a car product but would it be able to go below 20hz in a ported box?

Asked by: Andy Mac
In a nutshell, no. This driver has very limited excursion and very large box volume requirements. A large box will allow for a low tuning frequency, but the amount of output you will be able to get will be severely limited by excursion. In the recommended vented box for this woofer, you could not feed it more than 10-15 watts without reaching excursion limits.

With a listed sealed box volume of 7.11 Cu/ft per woofer, would two of these work as infinite baffle subs with my 14 Cu/ft trunk as the box? If so would rms power be reduced at all? Thanks

Asked by: TammyT
Yes these will work as a free air type subwoofer. Power handling will not be reduces but you will want to keep an eye on excursion levels at higher volumes.
