A shallow-mount sub that rocks

Pioneer's TS Series of shallow-mount subs bring great bass to vehicles where conventional subs won't fit. Their low profile allows the use of slender enclosures that'll fit behind a truck seat or in any tight space while delivering the bass performance you need. The TS-SW2502S4 10" shallow-mount sub handles up to 300 watts RMS with a mounting depth of just 3-1/8".

The TS-SW2502S4 features an oversized cone made of mica-injected molded resin that moves more air and delivers accurate bass. The sub works best in a small sealed enclosure, making it ideal for fitting those tight spaces in today's smaller vehicles. Pioneer recommends the UD-SW250D downfiring enclosure or the UD-SW250T truck-style enclosure (sold separately) for use with this sub.

To drive this single subwoofer, we recommend a mono amplifier rated between 260 and 525 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.

Features

Shallow Mount Woofer: Pioneer's Shallow-Mount subwoofers are designed to provide installation options for a broad range of vehicles. They can be mounted behind or under the seats of many vehicles. The TS-SW2502S4 has a Mica reinforced IMPP (Injection Molded Polypropylene) composite cone. The process of bonding reinforced pulp to the back of the cone improves its damping capability and eliminates excess vibration. The oversized cone structure provides more surface area without changing the external dimensions, producing louder and deeper bass by moving more air.

Terminals: The spring post terminals will accept pin connectors, single banana plugs, or bare wire up to 10 gauge.

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 0.5ft³ to 0.7 ft³; within this range the ideal size is 0.6 ft³ with a single 3" diameter x 13" long port.

Bandpass Box Volume: The bandpass box sizes recommended by Pioneer range from 0.35 ft³ per chamber to 0.6 ft³ per chamber; within this range the ideal size is 0.45 ft³ per chamber. One 3" diameter x 4.5" long port should be used in an enclosure with 0.45 ft³ chambers.

Amazing first time sub. Puts real sound quality to your music. But if you are looking for a hardcore system there is better ones out there.

Pros: Really small and compact. Great sound quality. Easy to install

Cons: Doesn't hit as hard as a 12 inch.

I Bought the old version of this sub over a year ago for my single cab s10. This sub will be more than enough for genre's like rock, country,rap/hip hop, electronic and more. This sub hits hard and will shake my whole truck without distorting.

Pros: Shallow mount can fit in almost any vehicle with a custom box, great sound, great price, versatility.

Cons: This sub is power thirsty, you will need a good amp to power it.

We've verified that these enclosures are a good match for this subwoofer.
It's critical to have good wire, and none is included with the sub.
Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
These can be useful if you are building a custom box.

You should only wire your subs in parallel they are each 4 ohms that will drop the to 2 ohms and you will get the most out of your amp. Parallel is positive to positive negative to negative [ Pioneertech  Oct 23, 2014 ]
I always suggest that you run the power and RCAS on separate sides of the car and keep the turn on wire with the power wire [ GARRETT  Jul 21, 2014 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Greg  Jul 19, 2014 ]  Staff
