Loud and proud

Pioneer's Champion Series PRO TS-W3003D4 delivers the chest-pounding bass you expect from a 12” subwoofer. Its rugged construction enables it to handle up to 600 watts RMS without a problem, for performance you can count on. This sub offers the versatility of dual 4-ohm voice coils (DVC) and the ability to work in a sealed or ported enclosure, so it'll fit right in your system, no matter what type of bass you like.

Keep it in line

Pioneer uses a larger magnet combined with a dual spider design to promote the accurate linear motion a subwoofer needs, just like a piston in an engine. The heavy-duty motor structure guarantees accurate response, so you'll enjoy greater clarity in your bass. The sub's reinforced basket houses a tough polypropylene cone with a dual-layer elastic polymer surround, giving you a durable sub that can handle just about anything you throw at it..

To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Reproduction is spot on, classic rock in sealed BB125 is a like, the pair are handling MTX"s 1000.1 500RMS a piece very well, just got the warm smell from use. I am very satisfied. They are heavy, to me that means rugged construction. Thank you Fletcher with help for the order

Pros: They have a pro look, with the proper RMS wattage they rumble, worth the investment. Happy with the purchase.

Cons: Not so far

No joke they are every bit the reviews were raving about.

Pros: They have incredible range, crystal clear sound quality and hit like a $500 sub. They handle large amounts of power without flinching.

Cons: Cost seemed high compared to competitors but they are not "licensed dealers" like Crutchfield is. If there is era problem with them at least having s licensed seller to back up the product will be helpful.

Great subs
