Great idea, but you missed one thing. You should make it into a bass trap as well.

On the front side of the bench? The top will be upholstered and I'll have a few throw pillows along the wall...

[locutus]

You have essentially built a bass trap. Leave the hinged top wood or upholster as planned. The front and sides can be opened to allow LF sound to pass. Line with OC 705, or equiv. You could either remove the wood on front/sides and leave a frame structure to bear the weight of the two drummers , or perforate the existing panels. You have a variety of options to taste: slats, holes, open, fabric wrapped, or wood. Keep the perforation percentage high so as to not create a hemholtz resonator, unless you do those design calculations.

You could even make it a tuned resonance absorber, such as hemholtz or panel, but this would be much more problematic, as the top would have to seal well, and changing the contents stored within would alter the volume and therefore the tuned frequency. You are probably better off sticking with a wideband absorbent trap.

The fiberglass lining will cost you a bit of volume in the box, but make it a useful bass trap. I like the idea of the bench/storage, but it also works as a trap with little effort.

I have used similar ideas for end tables/storage/traps, closet/trap, and a lower soffit/trap/cable tray/seat/shelf ringing 3 sides of the room. I am about to try and turn my ugly wood fireplace mantel into a new mantel/absorber or maybe a mantel/QRD to go with the grand piano in the same room.

Thanks for the great idea. There is still plenty of room to stuff another 4" of Rockwool on the inside front of the bench.

Man, I cannot wait to see how that desk comes together.

I'll post a few pictures soon. The laminate tops are done but I'm waiting for the construction dust to settle before loading up the racks.

I'm going to take your "sound" advice and turn the bench into a bass trap. I'll post pictures of the process. This project has taken so many twists and turns as my knowledge of sound control has evolved. I actually built the bench before researching bass traps so I'm glad the frame will be of some use besides seating and storage The broadband absorber plan seems like the best approach for this small space.

After building and painting the first round of sound panels, I decided that the coverage on the doors was lacking so I built a few more frames. Here's a closeup of the raw frame on the door and another shot of the aluminum French Cleat I've been using to hang all the vertical sound panels. These Cleats come in 4 foot lengths and are cut to size. I used a regular wood blade on my table saw to cut these since my metal blade took forever to make the cuts. I used metal bolts, nuts and large fender washers on the backside to secure the cleats to the wood. After building more than 25 of these, I can actually knock one of these out in less than an hour. Don't ask me about the first few

Here's a link to the French Cleat supplier: United Manufacturer's Supplies - Picture framing supplies and picture framing equipment and a link to the actual Cleat: Super Cleat Hanger

Sounds great. You have little to lose, except maybe a null. I look forward to the pictures.

Can't tell from the pictures... Will that open frame be a first reflection point between the speakers and your head?

If so, put 4" rockwool there. If not, just leave it.

Any diffusion that'll do any good will be 10-12" deep, and you are really close to it....

The open frame on the ceiling? It's not the first reflecting point but I do have some clouds behind my seat.

Awesome thread. How did it turn out?

[heshian46]

Im also curious to see some pictures of the final result.

Any news?

[dboybeats]

looks great

jetpackstudios-

Finish 'er off?! Sound samples! Pictures! Sweep results!

You've done so well so far, we're excited to see how it turned out!

[erikdrink]

Nice thread!

[alexvdbroek]

Super cool man

[poopynuggeteer]

Final pictures please!!!! Also I chuckled at the kill 2 drummers with one cymbal remark. I'll prolly use that again if thats ok :D
