Engineered for performance

JL Audio's CP208LG-W3v3 MicroSub enclosed subwoofer system delivers impressive bass without needing a lot of power or taking up much space. This MicroSub handles up to 500 watts RMS, housing two 8" W3v3 subwoofers that offer impressive low end. The enclosure is designed from the ground up to get optimum performance from its drivers, so you get much more than just a box with speakers inside.

 CP208LG-W3v3 MicroSub enclosed subwoofer

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, steel-mesh grilles, 5-way binding posts, and solid internal wiring. The enclosure is finished and inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

specially designed, slot-ported enclosure

Small enclosure, big sound

The specially designed, slot-ported enclosure measures just over 5 inches thick — it'll fit just about anywhere but it's an especially good candidate for regular cab pickups. Its flared slot-port design cuts down on air turbulence and keeps your bass rich and clear. You'll enjoy thick low-frequency response from all of your music with this capable enclosure in your vehicle.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Features

Overview: The CP208LG-W3v3 MicroSub is a compact bass solution for vehicles with limited space. This slot-ported enclosure is loaded with two 4-ohm 8W3v3-4 woofers, internally wired in parallel to present a 2-ohm load.

Enclosure Design: 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 has its own airspace and is protected by a black steel-mesh grille.

Flared Ports: The enclosure has side firing slot ports. The flared port opening minimizes turbulence and improves overall fidelity. The ports are 1-1/2" high and 4-1/8" wide at the openings and wrap around two walls of the enclosure to produce the necessary low tuning frequency.

Driver: The 8" W3v3 drivers have the following features:

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
  • Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar 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 weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.
  • Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.
  • Elevated Frame Cooling: The elevated frame design of the W3v3 delivers high-velocity air flow 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.
  • Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.
  • Customizable Trim Ring: The woofer comes with a removable ring made of black ABS plastic which can be painted to match the installation theme and create a personalized look. You can purchase optional grille mesh inserts which are specifically designed to fit into the inner diameter of the trim ring.

Works as Advertised ! I have had lots of subs in the past , I love to try different things. I was running 2 Alpine bass subs in a sealed box, not getting the bass I wanted, was missing all the lower notes. My Alpines were resonating the high bass notes louder than the low ones. I did not have room to use a ported box on the Alpine 10's, so I got this ported JL box and gave it a try. Running a Alpine PDX-9 , Kenwood DNX 6990HD, The JL box did what it was designed to do , It plays loud, clear, and covers the bass spectrum very well , Gets low , sounds good with all types of music. My Alpine 10"s worked fine , but only sounded good on certain songs. The Alpines just dont sound good in a sealed box. The JL 8"s can keep up with the alpines in SPL and do a great job of making all songs sound good. These JL will not beat the block with loudness , but if you are looking for your own personal bass , these will do great. Good choice for all types of music , will outperform other speakers by far. Its hard to beat a factory tuned box. After all the stuff I have used in the past JL never disappoints me.

Pros: small form factor , plays all bass notes very well.

Cons: none

Don't Be fooled by the size!!

Very pleased with this enclosure. I have a JL JX500/1 running the subs and they sound spectacular. The enclosure is thin enough to place behind the back seats of a 2013 Toyota Tacoma. I have been installing my own stereos for 28 years and I'm amazed how much bass can come out of this enclosure. I play all kinds of music and it can handle the bass! You will not be disappointed. Great for a truck set up or Hatchback.

Pros: Sound quality is great.

Cons: Nothing! If you don't enjoy this enclosure . Something is wrong with you!

Starts window flex on 20 hz!

Crazy amounts of bass! Doesn't rob needed space in the hatch. Love that I can hit every low note with no prob. Have a jl 900/5, 500 rms running 2 ohms to the MicroSub box. Engineered and built in South Florida! United States of America. What else you want.

Pros: Surprising friends, winning a bet here and there. 2 yr warranty.

Cons: None. Hope they keep bumping

Believe the hype!

First off, if you are on the fence about this product just go ahead and hit the buy button right now. I was very hesitant to purchase this loaded box even after reading all of the positive reviews for the single sub version. I just simply did not believe that this box could produce sound on the level of two twelves or even two tens. Well, let me tell you, I am now a believer. I have a '99 Chevrolet S-10 single cab pickup and this box fits perfectly behind the seat. I am even able to leave the seats as far back as they will possibly go and there is still room for both this dual 8" box and my 1200 watt Audiobahn amp behind the seat. My last vehicle was a '95 Camaro and I had two Infinity Perfect 12.1's in a sealed box in the hatch. I am not joking....this box with the two 8" W3's hits harder and deeper than the two 12" Infinity's I had in the Camaro running the same exact amp. Now, some of the wow factor may be due to the greatly reduced amount of cabin space to fill in the S-10 but I still believe that these subs and box are very high quality and live up to all of the hype. Go for it. You will not regret it.

Pros: Very nice box, great quality, superb sound, tight, clean, and punchy bass!

Cons: Price is definitely high. Like others have said before me, you get what you pay for. (search for promo codes before you buy....I saved $25)

Great Sound from this compact sub setup

I put this in my 2012 Ford F-150 XLT and hooked it up to JL Audio JX500/1D amp. First off this sub enclosure will fit easily under the rear seat and the amp also fits under teh rear seat. This setup takes up very little room where space is a valuable comodity. The sound from this setup is amazing. I purchased and installed this setup and expected to fill out the sound in my truck and was blown away by how hard teh bass hits and how clean and clear the sound actually was. Don't be folled by the size it will provide you with more than enough punch into any type of music you listen to. I would also recomend the amp remote control. It comes in very handy as I switch from different types of music and have teh ability to change the bass output at my finger tips. I can't say enough about teh quality of sound, power of the punch and it can all fit under the seat without any alterations to teh truck. If you have an F-150 you won't find a better setup for any type of music.. HIGHLY RECOMEND!!!!!!!!!!!

Pros: Size, clean sound, amount of bass 8" can put out

Cons: Price is a little high but you get what you pay for

Great!!!

I was like a few of you that had to test this product to believe the quality and hype. I am an audiophile since I was a teenager and now I am now almost 40. I have had many brands and various sizes in my day. I must say I am impressed by this box on it's ability to handle the deep and punchy bass that I was looking for. It fit perfectly in my 07 single cab Tundra and it sounds amazing. I highly recommend this box if you are looking for a great all around sound for your car or truck. I listen to a wide range of music and it made the grade. I feel it is worth the price tag.

Pros: Well built american quality

Cons: price!

Mediocre

I bought this to fill out the low end in my 2003 Roush Mustang convertible. I'm running Kicker 6x8 in my front doors and Kicker tweeters in the upper speaker pods, Kicker 6.5 in my rear all run with a Kicker ZX700.5. I have a Kenwood Excelon 6850 controlling it all. I was told that in order to get some bass from the trunk to the cabin would require a ported enclosure. There is NO room in the trunk of a convertible so I was pretty limited in choices. I bought this after reading some online reviews about how these "blow people away". Some say "people believe I'm running 10 or 12s". I'm from the old school and have run many, many set ups and can tell you that this is mediocre, at best. I'm throwing 420 watts RMS at these subs. They are rated at 250 RMS each sub so you would think that 210 per woofer would be perfect. Well, after tuning I hardly get any output out of these things. Raising the gain or God forbid the bass boost results in slightly more output heard in the cabin but when I pop the trunk the subs bottom out. Don't believe the hype. You're getting the output of two eight inch subs, PERIOD. Nothing more, nothing less.

Pros: Cosmetically attractive, JL name

Cons: You are paying for the JL name. Not enough bass to run in a trunk set up. Probably best to go under the rear seat of an extended cab truck. Expensive

It's critical to have good wire, and none is included with the sub.

I have the JL Audio JX500/1D with the bass control knob. A quality amplifier of this output should do. [ JOSE A  Jun 23, 2014 ]
I went with the Pioneer GM-D8601. It is 500 watts at 2 ohms and comes with the bass boost know while only being $200. It sounds Great in the back of my 2005 4runner. Highly recommended for the price. Hope this helps. [ TREVOR  Jun 23, 2014 ]
For details on installation please contact an Advisor by phone or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation. If you run into any issues during installation our Tech Support team will be happy to help. [ Jeff  Jan 01, 2014 ]  Staff
This would not be recommended as you would need to add a separate set of terminals for the second subwoofer wiring (which would mean modifying the box). For details on a sub box that might fit your needs please contact an Advisor by phone or online chat. [ Jeff  Dec 31, 2013 ]  Staff
