W3v3 8-inch Subwoofer
If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion. The 8W3v3-4 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
Dynamic Motor Analysis
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. DMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.
Elevated Frame Cooling
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. Many speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.
Floating Cone Attach Method
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment. JL Audio's patented FCAM™ technology is an innovative method of bonding the surround/cone assembly to the voice coil former/spider assembly. This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centering at high excursions.
Vented Reinforcement Collar
JL Audio's Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance. The Vented Reinforcement Collar (VRC®) is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes.

I have one of these behind the seat of my pickup truck. I listen to a lot of hard rock and heavy metal, and, both of these types of music have just as much bass as a lot of rap songs do. I LOVE these subs. I am used to 10 and 12 inch subs, so, when I decided to buy one of these, I was sceptical. I was really wrong. These subs hit hard and can really take a beating. I have this teamed up with an MTX 400 watt Terminator amp. I highly recommend these to anyone who has a truck or a small trunk and want an excellent sub.
I have 2 of these (8W3v3) in a 2004 Trailblazer EXT.. I built my own enclosure which is a simple rectangle box,construsted out of 3/4" MDF with .51-ish cubic ft of sealed air space(Ea chamber)...No filler or braces... Thier powered by a 900w Kenwood Mono sub amp.. Not the best I know but will due till funds are right.. Lol
THESE THINGS BLEW MY MIND!!!!! They hit SO HARD for 8's!!!!!! People are simply amazed when I show them.... Even my friends that have systems,cant believe that 8's can even MAKE sound like that!!!! I feel and sound like I got a pair of 10's atleast!!! Got a Datsun Z that I was in search of a small sub for and I found it... If my Trailblazer EXT is bumpin with 2 8'S the Z should be WANGIN!!!! Lol I've owned and spent alot on stereos and in my life and finally learned,that QULITY PRODUCTS make a world of difference!!!!! These JL Audio 8W3v3 are DEFENITILLY worth the buy.. If you want nice hard hittin QUALITY sounding bass sub,this is definitiy it!!!
The SOUND of the bass is so intoxicating and enjoyable... Im also runnin Orion 6.5"s in all 4 doors running off a 4 ch. Orion 50x4 rms amp so my highs and mids are nice and chrisp also.. The head unit is a JVC 7" in-dash touchscreen dvd player.. All bought from Online car stereo.com!!! Except the Kenwood Amp.. Best Buy sale.. ;) Jl will be replacing that soon.. Thanks a million Online,for helpin me save money,your bomb service and for your selection of QUALITIY products!!!!
I have a pair of these in a JL box behind the seats in my '03 Ford Lightning. I am running 175RMS to each and they aren't broken in so I keep them low. So far they are as improssive as most 10's and some 12's. I gage them with Usher's OMG and the percieved loudnes compared with a pair of Orion HCCA 10" I ran in my 2005 Ford 500 Limited. That ride had 3600RMS each 10 and werent as punchy as these little JL's, but the JL's wont play as loudly below 30hz. Bad ASS and impressive, but expensive at full retail, manageable here OCS!
