Champion Series Pro subwoofers from Pioneer combine big-time power handling with rugged construction for competition-worthy bass that hits hard. They'll sound great in smaller sealed enclosures, thanks to the unique Air Suspension System — it provides a spring-like effect to maintain clear, high-impact bass.

Unique suspension
Pioneer's Air Suspension System features a dual-cone structure — a main cone and surround at the top connected to an internal drive cone and surround beneath. This unique suspension system uses the air trapped in between to propel the main cone with outstanding accuracy and low distortion. The injection-molded polypropylene cones are reinforced with basalt and carbon fiber for outstanding strength and quick response, while the wide-roll, three-layer surrounds keep the cones on track and hitting hard during deep excursion.

Heavy-duty motor structure
A double-stacked 88-ounce magnet powers the motor structure in this competition-quality sub. A rugged die-cast aluminum basket anchors the sub, providing superior damping and increased magnetic efficiency for peak performance.

Serious power handling
The TS-W2502D2 10" sub handles 800 watts RMS for thunderously thumping low end. The dual 2-ohm voice coils allow you to set up a high-powered system with a compatible low-impedance amp. You can wire the sub for 1- or 4-ohm impedance — Pioneer makes it easy for you by putting the terminal connections for both voice coils on the same side of the sub.

To drive this single subwoofer, we recommend a mono amplifier rated between 600 and 1200 watts RMS at 4 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.

Product Research



Woofer: The TS-W2502D2 has an interlaced Basalt/Carbon fiber reinforced IMPP (Injection Molded Polypropylene) composite cone. This cone design is lightweight and rigid, resulting in clean, powerful bass response.

Cast Aluminum Basket: The one-piece cast aluminum basket assembly holds the motor assembly, cone, and magnet structure securely in place. The benefits of this design include reduced internal stress, superior damping, and increased magnetic efficiency.

Air Suspension System: Rather than using a standard spider to control cone movement, Pioneer created an Air Suspension system; using two cones with a sealed air space between them. The air locked between the main and drive cones creates a spring-like effect between them moving in unison. The dual cone structure maintains better linearity, resulting in consistently clear, powerful, wide ranging bass response.

3-Layer Urethane Surround: The surround uses two layers of urethane with a layer of interwoven fiber between them to add strength and stability and reduce cone distortion.

Dual Voice Coils: For increased system flexibility, the woofer has two 2Ω voice coils. The two sets of spring compression binding post terminals are side-by-side for easy wiring. Each post will accept a pin connector, a single banana plug, or bare wire up to 10 gauge. The two voice coils can be wired in series to present a 4Ω load or in parallel to present a 1Ω load. Additionally, each coil can be connected to a different amplifier channel and each channel will see a 2Ω load.

Dual Mass Magnet: The TS-W2502D2 uses a Dual Mass Magnet assembly (weighing in at 88 ounces) to create a powerful magnetic force. This increases the control exerted over the voice coil and the power transferred to the cone.


Sealed Box Volume: The sealed box sizes recommended by Pioneer range from 0.35 ft³ to 0.7 ft³; within this range the ideal size is 0.6 ft³.

Vented Box Volume: The vented box sizes recommended by Pioneer range from 0.6 ft³ to 1.2 ft³; within this range the ideal size is 0.9 ft³. The ideal port size for a 0.9 ft³ enclosure is 3" diameter x 3.5" long.

Single Reflex Bandpass Volume: The bandpass box sizes recommended by Pioneer range from 0.6 ft³ per chamber to 1.0 ft³ per chamber; within this range the ideal size is 0.8 ft³ per chamber. One 3" diameter x 7.75" long port should be used in an enclosure with 0.8 ft³ chambers.

Power Handling: The woofer has two 2Ω voice coils; each coil can handle up to 400 watts RMS (800 watts total).
