Powerful output, beautiful bass

JL Audio built their High Output Enclosures to give you a great combination of high sound quality and powerful output. Engineers at JL Audio used a patented chamber-coupled port design to maximize bass production, and this unique enclosure is assembled by hand to exacting standards by the craftsmen at their Florida plant.

Tough 12" sub

The HO112-W6v3 is built around the 12" W6v3 subwoofer, which uses its rigid polypropylene cone to push plenty of air for some serious bass output. Extensive venting helps prevent thermal breakdown in the voice coil, so you'll get lasting, consistent performance. The enclosure is wired for 2-ohm total impedance and will handle up to 600 watts RMS.

Patented ported enclosure

JL Audio makes this enclosure from CNC-cut, industrial-grade 5/8" medium density fiberboard, covered by thick gray carpeting, The recessed mount for the speaker offers protection for the driver; a grille is also available separately for additional protection.

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.

- Output for the box size is great. However you can build a similar sized slot ported box and save money if that's your thing. - Value is way overpriced for the added enclosure. There really isn't any special about the box itself, it's a standard slot port but they curved it which doesn't really do anything different than the typical L shape other than to say at the most this may decrease port noise but very unlikely to notice. I did an SPL comparison with a W6v2 in my custom enclosure tuned at around 34 hz and got the exact same results. - Subwoofer produces deep lows, coupled with it's strong motor it's definitely the reference model for all other subs. I listen to a lot of rock/metal that tends to peak in the 70hz range, so to cope, I tuned my gain to a test tone of 60hz @ -10db's. This allowed me to get the most power out of my amp for this kind of music. Plotting your music to find the peak is important for gain adjustment, otherwise the bass may disappear into the background when it shouldn't. - Easy to use: You'll spend more time breaking down and discarding the shipping box than hooking this sub up in your car. For hatchbacks, always anchor it down, otherwise it can turn into the Grim Reaper, beating you to death if you get into an accident.

I recommend no less than an XD 600/1 amp or to say at least 600 watts rms. It will handle 800 watts just fine all day long. Despite the specs, it craves power.

Pros: *Aesthetics: Looks clean and professional but I find the large brand embroidering a bit conceited. A full mesh grill covering the front would really polish it off. *Sound: Excellent quality with a wide range of music. From Rap to Death Metal, it can go deep and still provide high speed, precision kick drums where many other subs would fall off the scope. * Size: For a ported 12" enclosure, it doesn't take up much room. * Loud: Yes it can and you might as well remove your rear view mirror.

Cons: - No way to lock it down for a hatchback...a simple U-bolt in the back would suffice to provide an anchor point to run a bike lock through it to prevent the enclosure from flailing around if you got into an accident. - Very pricey. There's no real reason to charge this much in comparison since there are similar loaded enclosures, cheaper that would still satisfy average joe. - Great for small cars and hatchbacks.

All I can say is wow... I have been searching for a single sub solution that would work well to fill the cab of a Buick Enclave, without sacrificing a lot of cargo space, for some time now, and I think I have finally found my solution. Sure there are other, cheaper ways to have gone about it, but I have not heard anything that comes close to the sound quality of this sub and box combo. Everything I have tried before this either sounded good, but didn't deliver the "punch" I was looking for, or they were very loud, but without much music clarity. This JL W6v3 in its matching H.O. box fulfilled the needs of both sound quality and loudness for my Enclave! I am still surprised every day that something this small produces such hard hitting, clean bass!

Also forgot to mention that I have it paired to a JL Slash 600/1v3. Such a perfect fit for the 12W6v3!

Pros: Hard Hitting Clean Sounding

Cons: Price

I have this paired with a JL Audio JX 500/1D amp in a 2011 Ford Explorer. It hits really hard and clean. I have my bass knob turned up about 1/3 and you can hear me coming from blocks away!!!

Pros: Sound quality Don't need a huge amp (it's wired at 2 ohms)

Cons: It's large but I have plenty of room so no biggie

This product is loud it hits hard and clean. Deep lows and pushes a Lot of sound. All the sound I need in my c350 Mercedes gonna hav to dynamat the trunk and the doors it hits. Better and lower bass sounds than 12 twelves in my tahoe. Excellent product pair the two and JL does it again. If you want the best go with JL audio

Pros: Wide range of bass hard and deep it's what you want in a subwoofer. Bigger sound out of 12 than I've ever heard.

Product Research


H.O. Wedge Enclosure: The HO112-W6v3 enclosure is designed around JL Audio's 12W6v3 subwoofer, using V-groove MDF construction with internal bracing to ensure structural integrity. The patented, chamber-coupled port design wraps around the inner enclosure boundary and terminates just above the woofer, coupling the port output to the woofer's direct output. This also provides the necessary surface area and port length to maximize the performance of the driver. The woofer's dual 4Ω voice coils are internally wired in parallel to present a 2Ω load.

Terminal: The enclosure features one pair of 5-way binding posts on the right side. They will accept pin connectors, spade connectors, single banana plugs, dual banana plugs (standard 3/4" width), and bare wire up to 10 gauge.

Enclosure Dimensions:

  • Width: 14-3/8"
  • Height: 16-1/4"
  • Depth: 23-7/8"
