The TS-W303R 12" subwoofer from Pioneer's Champion Series sports a rugged cone made from injection-molded polypropylene and paper for rigidity without added heft. The sub's double cone design increases efficiency and reduces distortion, and the urethane surround keeps the cone under control for thumping output that sounds great in sealed or ported enclosures. And you can get all this performance without breaking your bank account.

A tough 6-layer voice coil allows the TS-W303R to handle up to 250 watts RMS. The stamped basket features a magnet cover for added protection, while the vented pole piece helps cool the sub's interior to protect against thermal breakdown. And the upgraded graphics on the sub give it a classic look you'll be proud to show off.

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.

Best sub in its price range!

These were my first subs I ever owned. Better subs are available, but, the W303r's are the best in their price range.

I initially powered two with a Sony Xplod 1000/2 amp (185x2@4ohms), but later replaced it with a Pioneer GM-D8601 (500x1@2ohm). The W303r's were in separate 1.25 cubic feet sealed boxes. They hit every note fairly equal and decently clean. The coils never overheated or stunk.

Later, I ran one sub in a 3.2 cube ported box @33hz, powered by a Rockford Prime 150-2 bridged. The higher notes were weak but the lows (30hz-45hz) were crazy. It was just as loud as my original setup, maybe even louder. I tried switching the amplifier's filter into the High Pass setting rather than Low Pass and the frequency response was well balanced. It played everything from 30hz to 80hz with authority. Tonality was amazing, very clean sound.

I've had many different setups. Some of the subs I have experience with are JL Audio 12w0v3, OZ Matrix Elite 15, Pioneer Champion Pro W3002D2, Sundown E-12v2, Sundown E8v3, Sundown SA-12, Rockford P3 12, Soundqubed HDS3-12, Pioneer W252PRS 10, and Alpine Type S SWS-1041D. Of all my setups, the W303r in a ported box with the High Pass Filter on was my second favorite setup, second only to my Pioneer Stage 4 W252PRS.

If you are limited on price and space, the W303r is a great option. Functions well in a small sealed box, highly efficient, cheap, clean sound, wide frequency response.

Pros: High sensitivity Good sound quality for the money Capable of playing up into the 60s and down into the 30 hertz range (good for the price) Optimized for large sealed box but still works well in a small sealed box (SQ) Very loud in a large, low-tuned ported box (SPL) Lightweight (saves gas, easier to handle) Sub is fairly shallow (only needs about 6" of internal depth)

Cons: Thermal power handling could be better (doesn't handle abuse well) Don't expect the W303r to handle over 250 RMS Low amount of linear excursion (5.9mm XMAX) Single 4 ohm voice coil (a 1 ohm stable amp would need to be 1000 watts RMS or more to be adequate)

great sub

Pleasantly Surprised

I am using to compliment to DLS 3-way front stage with 6.5 mid-bass, 3" mid and 1" tweet. The sub is crossed at 28hz to 63hz and powered with 300w RMS from by an Alpine M500. It's in a home made .85 cubic foot sealed box in my trunk, up against and firing toward the rear seat. I'll have to say, I am completely surprised by its performance. It's not going to go any lower than 28hz without breaking up, and it doesn't provide a lot of punch, so you'll have to use it with a goos front mid-bass. If you cross it properly and don't overpower it, you'll be happy. A sealed box would probably give it a little more "boom".

Pros: sounds great if powered and crossed-over properly. Has a nice look.

Cons: For this price range - none. Easily outperforms some more expensive subwoofers.

Great sound

This sub sonds great! I just replaced a 10" JBL with this one. The sound difference is amazing. I'm running it with 400 watts from a sony amp. It hits hard, but pushes deep loud bass at the same time. Pioneer is the best brand I've ever owned and I've owned almost all brands!.

Pros: Price, looks, quality, sound!

Cons: None

Pioneer TS-W303R

Written By BlairH, Buckley, WA on Wednesday, August 25, 2010

I bought one of these last week and its currently powered by a 760 watt pioneer amp in
my 1993 Ford explorer. I am very impressed although i cannot run at full power yet as I
need a cap. Hits neerly as hard as my friends Alpine Type R at a fraction of the price.
Hoping to buy another in the near future.

Pioneer subs have always been my choice for many reasons. Price, Quality, and overall audio quality produced by them compared to other comparably priced subs. Do a side by side comparison with these and any other subs you may be thinking about buying, take note that Pioneer subs will almost ALWAYS have higher sensitivity levels then the other.

What that means to you is more sound, less wasted power from your amplifier, higher quality audio even at low levels. Hard to beat that for the price.

Awesome Subs for price

Written By Superduty, Colorado on Friday, November 20, 2009

Bought 2 of these and put them in my Ford Superduty with a Rockford 1000 watt amp.
These things pound twice as hard as my Rockford Subs, doesn't hit the really low bass
as good but overaul I would buy these again and even pay double the price

Product Research



Overview: The Pioneer TS-W303R 12-inch, 4-ohm component subwoofer handles 1,200 watts max. (250 watts RMS nominal power), and features Pioneer's extremely strong and lightweight IMPP Composite Cone Woofer, for improved sensitivity and reduced distortion. The TS-W303R features a double cone woofer design with reinforcement nodes to deliver higher power handling and deeper bass, and a 6-Layer Long Voice Coil adds extra power and control. In addition, the woofer's Wide-Roll Urethane Surround provides excellent control for your big bass notes, and the woofer's Projected Pole Yoke with Vented Pole delivers tight, powerful sound with lower distortion.

IMPP Woofer: The Pioneer TS-W303R features an IMPP (Injection Molded Polypropylene) woofer cone. The IMPP cone design provides the strength and rigidity powerful bass sound requires.

Surround: The Wide-Roll Urethane Surround provides excellent control for big bass notes.

Voice Coil: The woofer's 6-layer long voice coil design allows expanded piston motion for better linearity, improved power handling, and more bass impact.

Projected Pole Yoke: The projected pole yoke extends the magnetic field, greatly improving linearity during large woofer excursions at high input levels.

Vented Pole Yoke: The vented pole yoke allows air circulation within the motor structure to ensure better heat dissipation.

Terminals: The heavy duty spring compression terminals will accept bare wire up to 10 gauge, pin connectors, and single banana plugs.

Optional Grille: We recommend covering up the subwoofer with the Pioneer Subwoofer Grille (130UDG308, sold separately). This stylish spoke grille is made of durable ABS plastic.


Enclosure Compatibility: The Pioneer TS-W303R offers great performance using either a sealed, ported, or bandpass enclosure.

Sealed Box Volume: The sealed box sizes recommended by Pioneer range from 0.85 cu/ft to 1.75 cu/ft. Within this range, the ideal size recommended by Pioneer is 1.25 cu/ft.

Vented Box Volume: The vented box sizes recommended by Pioneer range from 1.0 cu/ft to 2.0 cu/ft. Within this range, the ideal size recommended by Pioneer is 1.5 cu/ft. The recommended port diameter is 3". The recommended length varies with enclosure size; 6.5" long with the 1.5 cu/ft enclosure, 8.5" long with the 1.0 cu/ft enclosure, and 3.5" long with the 2.0 cu/ft enclosure.

Bandpass Volume: The bandpass box sizes recommended by Pioneer range from 1.4 cu/ft to 2.2 cu/ft. The ideal enclosure has a 0.9 cu/ft sealed rear chamber and a 0.9 cu/ft ported front chamber. The minimum recommended size has a 0.7 cu/ft sealed rear chamber and a 0.7 cu/ft ported front chamber. The maximum recommended size has a 1.1 cu/ft sealed rear chamber and a 1.1 cu/ft ported front chamber. The recommended port diameter is 3". The recommended length varies with enclosure size; 4.5" long with the 1.8 cu/ft enclosure, 6.5" long with the 1.4 cu/ft enclosure, and 3.0" long with the 2.2 cu/ft enclosure.
