Your favorite song is playing, you pull up at a stoplight, and pretty soon you've got the urge to launch an all-out drum solo on your dash — we've all been there. Maybe your drum set is imaginary, but you want the bass in your ride to be real as it gets. And that's where Pioneer's Champion Series subs come in.

The TS-W259S4 10" subwoofer features a seamless polypropylene cone that's injection-molded for exceptional precision and strength. The big, glossy cone features the classic Pioneer logo underscored with eye-catching red script, giving this sub the unmistakable mark of a Champion. Double layered elastic polymer surrounds support the woofer during cone excursion so you'll get right-on, hard-hitting bass notes.

A solidly built motor assembly uses a double magnet design to drive the cone hard for accurate, soul-shaking beats. So the next time you pick up those invisible drum sticks, you'll have this sub to back you up with loads of energetic, dynamic bass.

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.

I have only had this sub installed for barely a day yet, but from what I have heard so far, I am impressed. I wasn't shopping around for subwoofers that would blow my windows out, and I found this one and its perfect, especially for the price. This single 10 inch sub has great power for just one subwoofer, and is enough to rattle your rear view mirror like its nothing. I have it hooked up to a 1000W peak power, 300 RMS Sony Xplod amp, and the two work well together. I have it in the Sound Ordnance enclosure, and I am very impressed with how well everything works. The first time I drove after I installed it myself, I had to turn the bass level to 0 because it was throwing punches like crazy at levels 3-6. If you're looking for a sub that has great sound, looks great, and doesn't empty your wallet, this is definitely the subwoofer for you. Like I said, I've only had it for 24 hours so far, so I am hoping that it stays that way!

Pros: Price, Sound, Looks

Cons: Nothing I can think of!

Woofer: The Pioneer Champion series TS-W259D4 features a seamless IMPP (Injection Molded Polypropylene) composite cone woofer. The surface area is approximately 14% larger than last year's model for louder and higher quality bass reproduction. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. The cone is lightweight and rigid for low distortion and superior bass response.

Surround: The surround is made of dual-layer, fiber reinforced elastic polymer.

Terminals: The woofer's 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.

Double-stacked Magnet: The TS-W259D4 uses Double-stacked High Energy magnets 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 0.65 ft³ to 1.25 ft³; within this range the ideal size is 0.8 ft³.

Vented Box Volume: The vented box sizes recommended by Pioneer range from 0.9 ft³ to 1.5 ft³; within this range the ideal size is 1.1 ft³. The ideal port size is 3" diameter x 7.5" long with a 1.1 ft³ enclosure.

Single Reflex Bandpass Volume: The bandpass box sizes recommended by Pioneer range from 0.45 ft³ per chamber to 0.8 ft³ per chamber; within this range the ideal size is 0.6 ft³ per chamber. One 3" diameter x 6.5" long port should be used in an enclosure with 0.6 ft³ chambers.
