Our take on the JL Audio CP106LG-W3v3

by John Pollard
JL Audio

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.

Engineered for performance

JL Audio's CP106LG-W3v3 MicroSub enclosed subwoofer system delivers impressive bass without needing a lot of power or taking up much space. This MicroSub handles up to 150 watts RMS, housing one 6-1/2" W3v3 subwoofer that offers impressive low end. The enclosure is designed from the ground up to get optimum performance from its driver, so you get much more than just a box with a speaker inside.

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, a steel-mesh grille, 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.

CP106LG-W3v3 MicroSub

Small enclosure, big sound

The specially designed, slot-ported enclosure measures just over 5 inches thick, so it'll fit just about anywhere. 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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Overview: The CP106LG-W3v3 MicroSub is a compact bass solution for vehicles with limited space. This slot-ported enclosure is loaded with one 4-ohm 6W3v3-4 woofer.

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 Port: The enclosure has a side firing slot port. The flared port opening minimizes turbulence and improves overall fidelity. The port is 1/2" high and 4-1/8" wide at the opening.

Enclosure Depth: The depth of the enclosure is 5-1/4 inches, but the woofer and grille protrude an additional 1-3/8 inch, making the total depth 6-5/8 inches.

Driver: The 6-1/2" W3v3 driver has 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.

Nice little sub.

Written By Kris, Portage, MI on Friday, April 18, 2014
Crutchfield Customer Review (What's this?)
 
This little sub is a must for people with regular cab trucks. It fits with full use and motion of seats and center console. I replaced a fosgate r2 shallow sub with this, and the sound is comparable with 150 watts from an alpine X series amp. The fosgate sounded great, but this is a lot less invasive on my trucks useable space. I only gave 4 stars for value because its a little pricey, but I dont regret buying at all.
Pros:
I cant imaging a vehicle this will not fit into.
Cons:
Nuthin

Solid quality and construction

Written By Mr. Tim, Denver on Wednesday, March 26, 2014
Crutchfield Customer Review (What's this?)
 
Great quality sub which fits in smaller spaces and fills in the bottom end for cars without a lot of room. Great sound for only a 6.5" subwoofer.
Pros:
Great sound, great value, smaller size cabinet which will fit more places.
Cons:
This is a subwoofer for adding quality to a system, not for bragging rights.

Seeing is believing

Written By Can't get right, NC on Thursday, January 16, 2014
 
I needed a small sub to under my third row seat in my mazda. My first choice was larger subs but with the small area I had to work with ,a micro sub was my only choice. I must admit I was skeptical because when it comes to subs, bigger is better right?? We'll enter the JL. Audio micro sub. This little beauty is worth it's weight in gold. After reading the reviews here I felt good about my purchase however after installing the sub with a JL audio amp my good feeling turned into sheer joy and relief. Just as stated earlier this speaker has deep lows for its size. If you have very little space and you want more bass this the product you need.
Pros:
Small size, deep bass. Box size is optimal.
Cons:
None

You will not be Disappointed

Written By jjklongisland, LI, NY on Saturday, September 14, 2013
 
This microsub packs a punch. I was very picky with finding a sub that would fit under the rear passenger seat in my f150 supercrew. This sub fits perfect and sounds better than any tube or 8" sub I have ever heard and this thing is only a 6". It is very well constructed and provides a very clean tight sounding bass response. I would recommend this sub to pick up truck owner all day long who are looking to add additional bass without sacrificing space...
Pros:
Small, very clean sounding, high quality, JL performance

Great Sound Quality subwoofer

Written By AndyD, Baltimore, MD on Monday, July 22, 2013
Crutchfield Customer Review (What's this?)
 
Installed in a 1997 Honda Accord wagon with Alpine CDE-103BT HU, Alpine PowerPak powering 2 Focal Polyglass 2-way 6-3/4 front speakers and cheap 2-way Pioneer 6.5" speakers in the rear doors. A Kenwood KAC-819 mono channel amp (150x1 RMS) is powering the JL subwoofer: Guys, I am an audiophile trying to make my old Accord sound nice for daily driving. I want sound quality! With my setup, the audio sounds FANTASTIC! When people say this little 6.5" sub sounds like a an 8" or even a 10" sub, they are not kidding! I literally replaced a budget 10" JL Audio sub that was from ~1999 with sub. This thing sounds MUCH better than that did. One thing to note is that the 10" old sub was in a ported enclosure. This sub hits as hard as that one did and it has tight drum reproduction! That's one thing my ported 10" was missing. I am curious if this would sound as good in a sealed trunk. Remember, my car is a wagon so the whole car is open. For my needs, this is perfect, Now when I haul stuff in my wagon, I can quickly and easily remove it and put it in the footwell of the front seat. Before I had to take out the whole box before going on my trip. Worth every penny! I wish I bought this sooner!
Pros:
Sound quality and size.
Cons:
Speaker terminals.

Magnificent

Written By Nick C., Laredo, TX on Tuesday, July 16, 2013
 
Do not underestimate this sub due to its micro size. I had to make a hard decision between the 8" or 6.5" but in retrospect, I am glad I chose the 6.5"! If you're looking for tight, punchy, controlled bass, and you have limited space in your vehicle to work with - This is the one!! With adequate power, it will breathe new life into your current system! For the longest time I went without any subwoofer, and convinced myself my speakers sounded great - and they did, but I wasn't completing the full rich low frequency sound. Now, having upgraded my system with this carefully engineered enclosure and resilient 6.5 jl quality woofer, the double bass notes of dream theater now shake my bum. I will say, you will be surprised at how small this woofer appears in person, especially in comparison to the 8", but you'll be floored to hear the song it can sing!
Pros:
Quality box, quality woofer, quality sound.
Cons:
Limited power for those that like to turn the bass up. Although, this dependent upon the circumstances of your set up (power, amps, processors, LPF crossovers, etc.)

Perfect for a two-seater

Written By CntryJp, Mobile, AL on Saturday, March 09, 2013
Crutchfield Customer Review (What's this?)
 
I installed this sub in the opening between the rear storage compartment and the rear-right fender wall in a 2001 Honda Insight. The sub fits nicely (though snugly) in the opening, and when properly powered, it can deliver the same amount of bass response as the two 10" subs I had in the back of my Jeep Grand Cherokee way back when.

This little thing rocks! What's most impressive about it is it delivers tight, quick-responding bass with hardly any hesitation or muddiness. The sub has kept up well with the quickest double-bass drums and electronica beats that I've thrown at it, and it still delivers a similar 'punch' that you would feel with a significantly larger sub. There's nothing that I can see to complain about here -- even the build-quality is excellent. A very worthwhile purchase for a small car!
Pros:
Small form-factor. Quick bass response with a punch similar to larger subs. Tight, rich bass quality.

Great sound small package

Written By Anonymous, Rockport TX on Thursday, February 21, 2013
Crutchfield Customer Review (What's this?)
 
I purchased this sub for my wifes 2011 Ford Fiesta hatchback. It is powered by a 140 watt RMS mono amp by MTX. With the open cabin of a hatchback this sub can over power the factory speakers. We love the small size it fits well in the small rear hatch, and it is easy to move. The bass inside the car has good range, and feels powerful. Out side the car you can just barely here it, and it does not rattle the car at all. If your looking for added sound in a small package for a hatchback car you can't beat this tiny sub. We have had it now for a week and love it.
Pros:
Size Sound Sturdy grill for the sub
Cons:
Have not found any yet

Tight crisp bass that hits hard. I have the max 150rms pushing this little 6.5 and it has exceded expectations. JL audio subs are top notch. Fits perfectly behind the seat of my isuzu p'up. PLENTY of bass for mu taste which prefers sound quality over earth shaking bass, would buy again!

Plenty

Great for small cars

Written By Jose, Texas on Sunday, September 30, 2012
Crutchfield Customer Review (What's this?)
 
Great sub for small cars. I was hesitant at first going with a 6.5" sub. But the sound is nice and tight. I have a BMW wagon and needed a small sub that I could use in the bed and move behind the front seats when carrying cargo. I'm running this sub off a Kenwood amp connected to a JBL MS-8 off the OEM head unit. This sub is nicely filling in the bottom lows. I have the EQ crossover at 60 hz.

I tried small powered subs but didn't like the sound. This little sub with an amp is a great setup. Sound is smooth with no rattles. Build quality is excellent.
Pros:
Smooth base, no rattles. Tight bass. Build quality. Made in USA.
Cons:
Not enough low end bass, but I didn't expect that from this small sub. If I had the room I would have gotten the 8" version.

Compact 6-1/2" Sub that Sounds just as good as a 10"

Written By Peter, Demarest, NJ on Wednesday, September 12, 2012
Crutchfield Customer Review (What's this?)
 
I originally bought a JL 250W AB class amp and a Kicker CVT 10" closed sub about a year ago. I thought the 10" Kicker sounded awesome but always thought that it took up too much of precious cargo space on my 2012 Mazda5. So I contemplated on getting the Sound Ordinance low profile sub with built in amp. But wasn't sure whether I'd be pleased with the sound quality after coming from a 10" Kicker. Then looked at other options such as Kicker 8" sub with built-in amp but then price was slightly more than what I wanted to spend. So I decided on trying out the JL 6.5" amp with ported box. Now I was at first skeptical but figured with Crutchfield, there will be minimum risk in case I did not like it. Well, I received the amp today and plugged it in with same setting as my Kicker 10" sub; I then took the car out for a spin and seriously, I could not tell the difference between the Kicker 10" and the JL 6.5" -- actually, the JL sounded a lot cleaner and had just the same amount of oommph. I was also very impressed with the build quality, and the type of carpet JL used matches my black interior. However, the screw-on connecting post was a bit of a disappointment as my Kicker has those push on types which I like. But regardless, that's the minor compared to how small this sub is yet sound quality rivals (so far) that of much larger Kicker 10". It's only been a day but so far, I'm happy, will be interesting to see if I can fit this unit underneath the driver's side seat somehow.
Pros:
Compact size, sound quality, build quality, aesthetics, best of all, the JL name!
Cons:
Speaker wire mounting post.

JL Audio CP106LG-W3v3

Written By Eric G., Boston, MA on Tuesday, September 11, 2012
Crutchfield Customer Review (What's this?)
 
This is a great easy solution to add some low end punch to your system. Its not earth shattering, but it is also not weak. I actually was not expecting as much from a 6.5" woofer, but it sounds excellent. I have it under the rear seat of my 2011 GMC Sierra crew-cab, powered by the fifth channel of an Infinity Kappa Five amp. The sub provides tight punchy bass and rounds out the rest of my system very nicely. Exactly what I was looking for.
Pros:
Small efficient design, takes up very little real-estate. Bass response is impressive for a 6.5" woofer.
Cons:
A little expensive, but with JL Audio you get what you pay for, and that is excellence.

Great sub. I have this with a Fosgate 150 Watt RMS amp in an RX8, and it's just what i was looking for - compact, but packs a punch. This sounds as good or better than my old 10" Polk Momo. It's a tighter sounding bass than you'll get out of a 10 or 12, but it can definitely make the car shake. Great build quality and great sound at a good price - can't ask for more than that.

1 question already asked

would you need a sub woofer for this device? [ ian bernard  Feb 21, 2014 ]
6 answers
  • This is a sub woofer, so I don't understand the question ; ) [ Todd   Feb 24, 2014 ]
  • This is a subwoofer. You don't necessarily need an amp, but it would help. There are two wire connections that you could splice into you car stereo directly. [ John   Feb 24, 2014 ]
  • This enclosure includes the subwoofer. [ Andrew   Feb 21, 2014 ]
  • U mean an amplifier ? I don't understand ur question ? This is already a sub woofer.. [ JUAN   Feb 21, 2014 ]
  • If you mean speaker...no...there is already a 6" subwoofer speaker in the box that has a passive radiator...which by the way sounds great. If you mean an amp...yes...you'll need an amp. Not sure you what vehicle you're putting it in but it definitely has some kick especially for a six inch...you'll be surprised. If you are able, point it in a direction to make the most waves (like a Tsunami). If not, you'll still get some good bass but better if you can get it to bounce. Hope that helps. [ MICHAEL   Feb 21, 2014 ]
  • This is a subwoofer box with speaker all in one. [ BOBBY   Feb 21, 2014 ]
