Knock-Down MDF 2.0 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Ultimax Subwoofer

Even the easiest do-it-yourself subwoofer can turn into an arduous project; from uneven cuts, to measuring mistakes. CNC knock-down cabinets make it easy for the beginner to end up with amazing finished results without all of the time and effort necessary to perfect your woodworking skills. This cabinet is designed for speaker builders and designers who don't have access to expensive tools or a woodshop.

This particular cabinet is designed specifically for the Dayton Audio 12" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 12-3/8" or less, and a cutout requirement of 11-1/8" or less. For optimum performance with the Ultimax 12" subwoofer, add one pound of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 36 Hz.

During the CNC manufacturing process, rabbets and dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 3/4" rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle.

The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 12" Ultimax subwoofer. All that's left to do is finish it to match your décor or paint it to stand out. When your friends ask about it, you get the pleasure of saying, "I built it myself!"

Specifications: • Panel thickness: 3/4", front baffle is 1-1/2" • Panel material: Medium Density Fiberboard (MDF) • Finished net cabinet volume (subtracting the double thick baffle, bracing, and subwoofer volume): 2.0 cubic feet • External dimensions: 19" H x 16" W x 20" D • Subwoofer recess: 1/2" • Weight: 41 lbs. • Made in the U.S.A.

Knock-Down MDF 2.0 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Ultimax Subwoofer
Knock-Down MDF 2.0 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Ultimax Subwoofer is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Easy to assemble, quallity box.The first one I received had some really banged up corners. Parts Express took care of me and rushed out another which arrived in perfect condition. For someone like me who is not even a novice woodworker, putting this together has been a slow but simple process. The CNC cut pieces align perfectly, and all I have to do is glue and clamp.

Rated 5 out of 5 by from Knock-Down Boxes are the wave of the future!!!First review for Parts Express and a long time customer. I purchased 2 Dayton 12" Ultimax's and don't think they had these boxes yet. So after a failed ported box project, I ordered these knock down boxes and decided that this would be the way to go.I was skeptical because I have never had a sealed box but these Ultimax's are specifically designed for the 2cf boxes. Free shipping makes this is a great price and value. But if you don't own 24" clamps, that can be a high added expense.Never made a box without using screws either, but I purchased Titebond Ultimate for the glue.So the shipment arrived safe and sound. Everything fit and went together great. The only thing is you have to make sure your braces are "squared" because mine were not with just eyeballing. I had to sand the front for the panel to set flush.Other than that, the fit and quality of wood is awesome. The 3/4 inch partical board I have used all my life is not like this and MDF board which is not sold by Home Depot in my area. Its much more dense and does not chip.Well, I double stacked these and all is needed is glue - lolThe sound is great but I am still getting use to not having the room pressurized from a ported box but I like what I hear. I also have all ports plugged SVS PB13 Ultra along with this sub.I am using a 1200 watt Bash amp and these Dayton's will take everything I give them in these boxes.I will buy Knock Down boxes from Part Express again for other projects. It's the way to go for me!!!

Knock-Down MDF 2.0 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Ultimax Subwoofer

Could this cabinet be used as a downfiring subwoofer if furniture style base/or legs are added to the bottom creating a 4" gap from floor to the subwoofer?

Yes.

Will the baffle cutout accommodate Eminence Lab12? The dimensions of both the woofers look almost the same unless I am missing something.

Asked by: alok
Yes this should work well with the Lab 12 woofer.

Would one roll of the Band-It veneer sold here at PE be enough to finish all sides of this cabinet? If so, how much room for error is there?

Asked by: Sintek
One roll will cover the sides, top, bottom and back although we recommend painting the front due to the rounded over edges. Covering the 5 sides will leave roughly 10" of veneer left over.

For a music only application, which speaker is best for this enclosure?

I'm building a music only system with multiple subs in it. I have a pair of Dayton 18" Reference subs, currently mounted in bass reflex enclosures that are too small. The result is a big peak at 40 Hz. I'll be moving them to the new 4 cubic ft knock down boxes. I'll go with the 5 lbs of damping material for them. I'm not sure what that will do to the F3. I'm dithering over using the Dayton Ultimax 12, or the Dayton Reference 12 HF for the second sub. The goal is to get clean and rock solid bass all the way to the bottom octave. If this was an HT or auto audio application, the Ultimax 12 would be a no brainer. These are in the low pass circuit of the crossover network in my mains. I'll adjust the LC components when the configuration is complete, but currently, the low pass crossover frequency is at about 650 Hz. I have mid bass drivers in the circuit as well. Everything is in pairs. There are 2 6" drivers in parallel with each other, in series with 2 10" drivers in parallel, in series with 2 12" drives in parallel, in series with 2 18" drivers in parallel. Net impedance is 10 ohms. With all these drivers of different sizes, I'm hoping to avoid any annoying peaks and booms. OK, with all of that info, which driver is best for the 12" role? How much damping material? I haven't pulled the trigger yet, so I can change any of the drivers on the list except for the 18" subs.
Asked by: One sub over the line
Every loudspeaker has a resonance peak. Every cabinet reinforces a resonance. By using several different sizes, you may be multiplying this effect. Usually, I go with 18" or 15" subs--but I don't usually combine both. If this was a live music application, I would go with 2X18" accordion surround speakers per side in a vented box--Since you have several half round surround drivers, I would guess you have a large room recorded music system [I think]. As for dampening material, that's a minor issue, compared to your complexity of design. Sometimes, simple is better.

Fits 12" MK3 Titanic

Will this fit a Mk3 12" Titanic?
Asked by: pblarry
The volume will work although the baffle will need to be modified since the woofers have two different cutout sizes.

Grill cloth or metal grill options?

I've got a pair of Dayton Audio 18" subs, and I was thinking of adding a pair of Ultimax DVC 12s. My current cabinet for the 18s, has a metal grill. We have pets, so I would like to protect my speaker cones. Well, the cones are aluminum, but the surround looks like it needs protection. Do you guys sell any kind of grill cloth or metal grill kits for the 18" and 12" knock Down boxes?
Asked by: One sub over the line
Take a look at the examples below. I have lost a few speakers to cats & dogs myself.
