Ultra-Shalow Enclosure Design

Thanks to its innovative enclosure design, the TS-SWX251 enclosure can be installed freely in the cabin or luggage area for optimal utilization of space. The compact space-saving dimensions also make it easy to install the subwoofer in a variety of trucks- standard-cab, extended-cab, or crew-cab.

Air Suspension Excursion Control System

Enjoy deep big bass from a small enclosure. In order to create a subwoofer that is three and a quarter inches deep, Pioneer had to develop revolutionary subwoofer technology. A traditional subwoofer uses the spider design to keep the voice coil of the speaker aligned while it moves. This type of set-up can become soft over time degrading the subwoofer's performance. Pioneer created a patent-pending air suspension system that locks air between a main cone and a drive cone. The cones move together in unison, with the locked-in air behaving like a spring. The dual-cone structure is a spider-less design that maintains better sound linearity, and reliability even after many of hours of hard use. The pressure from the trapped air results in a consistent bass response across a wide frequency range. The result is a tight, precise movement with powerful and clean bass output.

Angled Push Terminals

Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force wires to be bent to fit which can be difficult if low gauge high performance wires are used. The Pioneer shallow subwoofer's patent-pending, angled push terminals make it easy to connect speaker wires. The straighter connection saves space and makes installation easier.

Downfiring Subwoofer Technology

By directing the subwoofer diaphragm downward, the TS-SWX251 radiates bass with superior efficiency for richer, deeper low-frequency sound regardless of the enclosure's installed position.

I have this running on a Pioneer GM-D7500M amplifier (200W @ 4 OHMS) and am very impressed with the performance.

The sub did take several hours to settle in and I had to adjust the gain and crossover several times until I found the sweet spot. I increased the gain gradually over the course of a few days and am delighted with the quality of bass now.

When I first plugged it in I thought "Oh, is that it?" but after some patience and adjustments it really shines. I wouldn't recommend this sub if you like window shaking banging/thumping bass, but if you are limited on space (I didn't want a sub taking up the entire trunk) and looking for tight musical bass - this is a great choice. I also really like the fact that it is down-firing as it protects the woofer from getting poked or damaged, and allows me to lay items on top of it in the event that I am transporting something bulky in the back of my car. The box is extremely solid and tight - and has minimal branding on it, so it won't attract thieves. It pretty much disappears into my car's black carpet.

I have it sitting in the hatch area of a Honda Fit, with the little Pioneer amp installed under the driver seat - so it is an ideal sub set up for those of you looking for something more compact and discrete.

Remember - be patient and spent lots of time playing with the gain and crossover until you get the sound you want. And give it time to break in.

***4 Month Update***

I have owned this sub for 4 months now and am LOVING it. I really thought I would have to settle for "average" bass due to my desire to buy something small and compact, but this thing has exceeded expectations.

Okay, to begin I bought I new F-150, and wasn't impressed with the factory sound. I replaced and amped the door speakers, but still wasn't 'Wowed.' I was really trying to avoid adding a sub woofer because I didn't want to sacrifice any space at all, but every sound store I went to said the same thing (your missing low end). While at the last sound store that I visited I saw this unit and asked "How much?" They wanted $200 for the same enclosure, so I hit up trusty Amazon. Here's the review.

While writing this I see the product title as Enclosure 800 Watts. Not sure if that is a mistake or what, but it is rated for 200 Watts. I am currently giving it 200 Watts (from a bridged RF 4 channel amp) and let me tell you, it will need no more. I've had sound systems that were insane in my younger days, so I know what to expect from a shallow mount 10" sub. I was surprised. Although I wasn't looking for something to set off car alarms, I wanted to add some bottom end to my sound. This exceeded my needs by quite a bit.

As a matter of fact I have the bass (to the enclosure) turned to half way and find myself wondering if I should turn it down a bit more. I was amazed. Reviews will tell you that it takes a couple of weeks to break in. This is true, but honestly, it sounds pretty awesome from day one. If you have any experience with sound systems and know what to expect from an enclosure this size, you will be more than pleased from the performance. It will not make the roof of your vehicle pulse up and down, you won't feel the bass in your chest, but for a 10" shallow mount, it is incredible. I listen to all kinds of music, from classic rock to the occasional delve into chopped and screwed rap, and this thing does not fail to deliver.

I normally don't submit product reviews, but because I could not find any reviews saying this would fit my Jeep I decided to take a chance on buying it, and I was very surprised to find it appears that it was made for the Wrangler. I have a 2004 Jeep Wrangler X 2-door. The Pioneer sub can sit flat (sub side down) in the trunk area and has just a small space between the tailgate and the seat. The seat actually sits just over the lip of the box. The sub sounds great. I was surprised the level of bass it put out and the overall fill it gave the system. I hooked it up to a Kicker 200.4 amp in bridge mode for amp 1 and my front and head speakers I connected to amp 2 of the amp. The amp fits under my rear seat and the sub lays down like I said behind the seat and there's room to put groceries and stuff on top of the sub - it doesn't consume all the trunk space. If you are looking for a sub for your Jeep Wrangler that won't use up all your space and still sound great, I recommend this Pioneer. You could probably build your own box setup but this one is about as custom as you can get for the back of your jeep without any work.

Hello
This is my first review ever for amazon.
I just installed this. Let me tell you that I'm impressed. Its very small but don't let that fool you. It really rounds out the deep sounds for me. It is perfect for my application as I have it in the back of a full sized suv. It feels very sturdy and I would have no problem stacking groceries, etc items on it. If you go to the pioneer website it give better photos of this then the stock amazon photos. Anywho.... to the best part. It sounds great, I have it running through an ancient RF punch amp and it hits HARD. Granted its an older RF amp and they are SERIOUSLY underrated. Its a sealed enclosure, so it"s a quick, solid hard hitting bass, rather than a really deep ultra low tone bass. It does need to break in and i feel that it will only get better after break in. I feel that for the price, its a VERY good value if you are tight on space and want a small sub that can really add to a punchy low end that can really round out a system. Now granted I know this is not a high end unit but i feel this should really be considered for anyone who wants more low end, and does not want to spend alot of money, but want the backing of a major manufacturer. Like i said, this is my first review ... and I really like how it sounds. It really rounds out my system.
