Amazing Bass For Limited Space

The CP208LG-W3v3 MicroSub is a compact bass solution for vehicles with limited space such as trucks or convertibles. This slot-ported enclosure is loaded with two 4-ohm W3v3-4 woofers wired to a final impedance of 2-ohms. The W3v3 subwoofer is one of the cleanest, most efficient, and best sounding subwoofers in its class. The W3v3 features a DM Optimized Motor System that provides constant and strong linear excursion that result in reduced distortion and higher bass reproduction. These woofers also feature Elevated Frame Cooling technology that delivers cool air directly to the voice coil of the woofer. This increases power handling and sound quality. The W3v3 series subwoofers offer many more patented technologies that truly make this series stand out above the rest. If you are struggling on a decision, JL Audio will never disappoint.

The enclosure features top quality MDF (medium density fiberboard), cut using state-of-the-art CNC woodworking equipment, and covered with high-grade automotive carpeting. Extensive interior bracing permits the use of thinner MDF that maximizes the enclosure's internal volume relative to its exterior volume. Each driver is also protected by a black steel-mesh grille. It also features a side firing slot port. The flared port opening minimizes turbulence and improves overall fidelity.

Every 8W3 subwoofer is built to exacting quality standards in JL Audio's Miramar, Florida factory. Each of the four models is a completely original design from surround to back-plate (even the bolts and screws used in assembly have been purpose-designed and manufactured to our specifications). Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

The way bass is supposed to sound !!

If you are a TRUE bass lover and want to hear and feel bottom end the way it was meant to be, JL'S double 8's is all you need ! And yes, they do handle 500 watts rms with the greatest of ease !! If your looking to annoy the neighborhood with prosessed electronic bottom end, get an 18, these arent for you. progressive, metal, jazz fusion lovers ??? You are gonna love this sub !! PS. I have this sub in the back of a suburban running with 4 R-series Alpine components.

Awesome little set of sbs

Bought these to get me by until I could build my own box... Wow was I impressed. These two 8s crank out the base. I had pretty low expectations, but these really perform and will probably stay for a while...

Nice setup

I really like that JL offers such a potent package at such a good price. W3s are a really good speaker. It took about two weeks for them to break in and after that I was really impressed.

skeptical but a believer now!

I don't normally review products but after hearing this profuct, I had to. Hears the meat and potatoes of my opinion. This product is very well built, looks good, and sounds even better. . I own a ford platinum super crew and I placed the sub box under the backseat. I have it paired with a fosgate p1000x1bd at 2 ohms and it absolutely slams for a pair of 8 ' s! Don't get me wrong, these 8 ' s aren't going to beat the block down but they will definitely fill the cab of your truck with plenty of bass as long as you feed these babies plenty of power. The only complaint I have is that they do occasionally have problems hitting the really low bass notes but you gotta remember that these are 8 ' s. They aren't 10's or 12's but regardless, I'm very impressed. In my younger days I owned plenty of other systems but for a family man with limited space, this setup is perfect. If you own a super crew ford and want some clean, precise, and powerful sound then look no further. You will definitely be impressed.

To my fellow F150 owners...

We all know its really hard to find anything that fits under the rear seat. This thing fits PERFECTLY and absolutely slams for 2 8"s. Wow, very impressed. Anyone who says differently doesn't know how to tune an amp/processor. Buy this thing, it's worth every penny.

I did all the research and was limited to teh space I had in my truck. I wanted high quality with outstanding sound. I hooked this sub enclosure up to my JL Audio JX500/1D amp with the remote and it absolutely blew me away. I have a 2012 F-150 XLT and this fits easily under the rear seat and produces bass like there are 12" in the bed. I can't believe this enclosure is so load, clear, and flexible throughout all types of music. If you have an F-150 and are thinking about anything other than this setup you will be disappointed if you don't go with this setup. You get what you pay for and by spending a little more you will definitely tell the difference. Highly recommend.

It's for real...

Was torn between this unit and the single 8 version of it. With this carrying a 2 ohm load and the single having a 4 ohm load this made more sense for my amp. Fits perfect in a small space under the seat and offers very clean, accurate sound. Way more bass than you'd expect to get from two 8's. Highly recommend this thing. Well done JL.
