Product Details

Denovo Audio Knock-Down MDF 0.67 cu. ft. Subwoofer Speaker Cabinet

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. Perfect for speaker builders and designers without expensive tools or access to a woodshop.

During the CNC process, dadoes are cut into the top, bottom, and rear of the side panels to ensure a secure fit, maximizing the gluing surface and making assembly that much easier. The front baffle features roundovers on each exposed edge for a professional look.

The end result is a subwoofer speaker cabinet that assembles in no time flat—all you need are wood clamps, wood glue, and about five minutes; no screws needed. 

Specifications: • Panel thickness: 3/4" • Panel material: Medium Density Fiberboard (MDF) • Finished cabinet volume: 0.67 cubic feet • External dimensions: 12" H x 12" W x 12" D • Internal dimensions: 10.5" H x 10.5" W x 10.5" D • Made in the U.S.A.

Denovo Audio Knock-Down MDF 0.67 cu. ft. Subwoofer Speaker Cabinet is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from Just the right size for a small subI'm using this box as a sub box for a 6.5in TB sub (#264-919). Fit was nice as these boxes usually are. You will need to do some sanding and filling to get it perfectly smooth. I opted to just cover it instead of painting. So prep was straight-forward as I didn't need any sealer. The amp, (#300-784) was installed and the port I used, (#268-248) along with the sub all fit perfect with the right internal volume I was looking for. I'm using this as my computer system sub box. Its small size is perfect and sounds amazing considering the size....

Rated 4 out of 5 by from Nothing fancySolid MDF boxes, accurate joints and cuts. I used 2 of these to test JBL 2118H 8" midrange drivers. Packaging should/could be better, the mdf showed the effects of a rough trip.

Rated 5 out of 5 by from Great sub woofer boxIt does affect which side goes where comming out to have perfect edges with no sanding when you take the time to check. Glued and screwed with a 10" eminator sub works great! Sounds great! Just looking for a finish and grate over the speaker face

Rated 5 out of 5 by from Well made 0.67 3/4 mdf subwoofer cabinet.Nicely machined box went together with ease. Mdf seems to be high quality compared to mdf available at home center. Saved me a lot of time and work by buying it already cut. Cut your driver holes add some binding posts and finish and it's done. Another great product from P.E

Would this be a suitable box for the DCS205-4 in a ported setup? If so what kind of tuning can be achieved? I was kinda thinking near 35hz or so?

Asked by: immageek
You would be better off with the 0.75 cubic foot enclosure. The smaller the volume the longer the port has to be to achieve a low tuning. A 2" diameter, 8" long port will tune to 35 in that volume but there may be slight port noise at higher levels.

would the Tang Bang W6-1139SIF work w/this enclosure ?? sealed or the 6 1/2 " passive radiators ????

Asked by: mpaci1001
This will work either way. If you use two of the Dayton 6-1/2" passives, I would recommend adding 35 grams to each for a tuning frequency of about 38 Hz.

can this box will work great with Dayton Audio D200-8?

Asked by: Jt32
This will work with that woofer if you keep it sealed.

I have ordered this cabinet (3007068) a tang band 6 1/2" sub(264-919) a Dayton 2.1 plate amp(300-771) and 2" adjustable tube(260-387).  What would the best length to set the port considering the displacement of the amp?

Asked by: mark47803
The best length of the port would be as long as possible, so about 9". This will provide a tuning frequency of 36 Hz.

600 grams? Did u mean 60grams??

Passive subs (2) in a #300-7068 0.67ft subwoofer cabinet. With # 295-458 RSS210-4 8" subwoofer. Yung 300 watt subwoofer amp w/o boost in separate inclosure.
Asked by: musiclover
600 grams sounds right. 60 wouldn't be enough to get near 27hz. That sounds high, but some PR's mass is aroung 250- 300g to start. Hope this helps and is right. Lol. Maybe Im about to learn something as well.

on what side do i put the 2 SD- 270-PR?

Do I mount the passives on opposing sides of each other or one opposed to sub and the other on bottom? I do have a Dayton classic 8" sub but want a H.O. Using a passive radiator is exactly what i first wanted 2 do but was unsure exactly how and what 2 use. Still a beginner @ most of this. Thanks for the help
Asked by: musiclover
Generally the passives will go on opposing sides of the enclosure.
