Denovo Audio Knock-Down MDF 1.5 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Reference Series HO 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 RSS315HO-4 12" Reference Series High Output 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, the cabinet is oversized to allow for the use of a plate amplifier with bass boost (such as the Dayton Audio SPA250 or Dayton Audio SPA500 plate amplifiers) to extend the frequency response while staying musical.

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" Reference Series High Output 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): 1.25 cubic feet • External dimensions: 15.5" H x 15.5" W x 16.25" D • Subwoofer recess: 1/2" • Weight: 37 lbs. • Made in the U.S.A.

Denovo Audio Knock-Down MDF 1.5 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Reference Series HO Subwoofer
Denovo Audio Knock-Down MDF 1.5 cu. ft. Subwoofer Cabinet for Dayton Audio 12" Reference Series HO Subwoofer is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Works like a dreamI got one of these with my new Morel subwoofer. Just some bar clamps and some Tite Bond II and you have a strong enclosure. Because it is CNC cut, everything lines up really easy. After assembly; hit it with a sander and paint, or veneer. I highly recommend this product!

Rated 5 out of 5 by from Great subwoofer inclosureI purchased this cabinet to house a reference series 12" sub I have. I originally had a sub120 that I converted to a sealed inclosure and was using the RSS315HO in it with a Dayton SA240 amp. I decided to upgrade the amp to a SPA500 but it wouldn't fit in the sub-120 cabinet. I decided to give this cabinet a try. It went together very easy and is very solid. I used clamps to hold it together while the glue set up. I bought a ratcheting band clamp that worked great and would recommend using one during assembly. I did find out there is some required trimming of the internal bracing in order for the SPA500 plate amp to fit. Without trimming there isn't enough depth for the amp to fully seat in the cabinet. The RSS315HO is a tight fit in the cutout face. It might have been some over spray when I painted it too. I just sanded the opening and it fits very snug. I caulked all of the interior seams as well. I ended up priming the cabinet and then painting it. I installed some speaker spikes on the bottom as well. So far it sounds great in my home theater setup. Much easier then trying to build one from scratch. I might purchase a grill kit to give it more of a finished look but for now I think it's fine. Also this setup is a tank as well. The finished product weighs 65 lbs!!

I'm wondering if the cabinet could be used for a sealed guitar extension speaker. Or should it be ported? the speaker I'm using is a Celestion B12 Vintage.

Asked by: JohnHS
I suppose it could be, although this cabinet is designed to be non resonant. Usually you will want a thinner, non braced enclosure for a guitar speaker. I doubt porting will add much benefit for an application like that.

I was hoping to use it as a woofer  for Rogers LS2 speakers, like a po boy Wilson Watt/Puppy.  The plan was to use my Dynaco st-70 on the LS2 and my Hafler DH220 on the Daytons, with an active crossover around 120-130hz.  Will it work?

Will this cabinet work well with a RE Audio XXX 12" dual 2 Ohm subwoofer?

Asked by: Ronin1971
This cabinet will work but the bracing will have to be heavily modified or removed in order for the sub to properly fit. The cutout on the baffle will also have to be made larger to accommodate the larger frame.

I'm having issues trying to stain my box with the color black gloss. Im testing with a piece of scrap wood and it bubbles. I can't get it to look smooth, even with primer. What do you suggest for paint/stain? Thanks

Asked by: Zjohn98709
I would recommend searching our Tech Talk forum for MDF finishing techniques. There are many threads and pages that deal with this very question, they should be able to help you with finishing this enclosure.
