IMPP Composite Seamless Cone

An extremely durable, yet lightweight cone is vital to prevent cone failure at high sound pressure levels. Pioneer's New IMPP Composite Seamless Cones meet this need perfectly while delivering accurate yet powerful bass.

Dual-Layer Elastic Polymer Surround

Another world's first from Pioneer. Dramatically improves durability and lightness for superior response, especially for louder volume.

Large Surface Area

A speaker cone is essential for air to vibrate and carry sound to listeners' ears. Our new Champion Series subwoofer cones have 14% more surface area than conventional subwoofer cones, for louder, better bass reproduction.

Single/Dual Voice Coil Design

Pioneer offers single voice coil (TS-W309S4) and dual voice coil (TS-W309D4) 12-inch designs. The Dual 4 ohm subwoofer has the flexibility to be wired at 2 or 8 ohms, to get the most from the amplifier. To simplify installation even further, all speaker terminals have been placed on one side of the subwoofer rather than on opposite sides.

Air Vent

The movement of air within the subwoofer is smoothly channeled for optimal ventilation to ensure a quick response and clear reproduction of bass.

I needed something to give me a little more bump in the trunk so I decided to come on Amazon to see what I could get for less than $50 that would help me fulfill my goal. That is when I came across a smoking deal on one of these Pioneer TS-W309D4 sub woofers (for less than $40 even). I've had Pioneer subs in the past and had pretty good luck with them, so I didn't think twice before I jumped on this one. After I ordered I found out that this isn't your cheapy Wally world cheapy Pioneer sub, this is actually the middle of the road that usually retails for twice the price of those. I could barely contain my excitement waiting for UPS to bring it to my door. I have it in an Atrend E12S B-Box sealed enclosure, filled with poly fill, and for an amp I am running Boss Audio R1100M Amp running 2-ohms and I just can't get over how amazing it sounds, more than I ever expected from a cheap Sub/Box/Amp. If I could give more stars I would.

I bought two of these subs for about 110$ and they are sooo worth it. I'm using a pyle 3000 watt amp brigged at 2ohms and they are doing work! The clarity of these subs is great. Do not waste your time anywhere else! I would 100% recomend a ported box.

These subs sound great. I have them hooked up to an xtant 1001dx amp and I'm running them at 4 ohms bridged for 250 watts rms. They're not even broken in yet and they pound. I would buy them again definitely.
