Basement Drumroom

This is the actual build diary of the drumroom which was designed here: viewtopic.php?f=1&t=11881 Little isolation, only acoustical dress up. Jup, just a nice little project :)

to start of: here's some pix of the room being preparted. It's been painted, a heatradiator is installed and lights are being replaced.

The broadband panels are being made and installed using a French Clead. It's semi-rigid rockwool, 44kg/m3, 5cm thick, 100cm high, 60cm wide. Build in a plywood frame and wrapped with fire-retardant cotton.

Details of the broadband panels construction As the title describes, here are some pix of the panel construction.

The panels we're hung using the "French Cleat" technique.

I really like that idea of one long rail along the wall, so you can mount your panels anywhere you want them, and move them around as needed. Smart! :) - Stuart -

yeah, who said Dutchies ain't smart :yahoo: It IS a very handy feature indeed, a panel can be mounted exactly where you wan'm. Next: the corner traps. Check the Design threat for more on that subject for the moment :) cheers mate!

:) !!! Extending your "smart" idea, you could even put maybe two or three such rails, at different heights, in case you need to move things up / down, or have panels stacked one above the other.... You can probably make it look cool, aesthetically too, with your creative artistic skills! You got me thinking seriously about my live room.... Thanks! - Stuart - (British / Australian / South African / Chileans are smart too!)

extending even further, how about a variable panel. A telescope or folding panel or sumpfin ;) Let's get creative indeed.

:shot: Mkaaay, corner absorbing devices! yeeeh. Here's a couple o' pic of the 2 devices we build (see the design in the design thread). It's the cheapest way to build a superchunk IMHO. A few pieces of plywood, plastic, cloth and trims are all you need. pix:

I just got word from Roeland (the owner of the room). He placed his kit in the room and gave it a try... He was very impressed by the sound of his kit in this room. It's tight, focused and it has no "whooomp" in the low-end anymore! Mission accomplished I'd say :)

Looks pretty cool, and if it sounds good, then great! Good job! (And there you are, making me jealous again, with a finished room.... ). - Stuart -

Well this room sure isn't the greatest looking room, but atleast it sounds good. Our goal was only to acoustically dress it. The colorscheme wasn't my choice, gheh. (yeah, but ugly blue and gray with white panels... not the best choice) It's just a basement with panels and a drumkit, easy project... NEXT! :)

One suggestion in order to get a perfectly stretched finish.. Stretch the fabric on the last framing you added at the end for looks. That way, you just nail it over, and nice stretched finish Nice ones!

You mean *this* one? Can't be done, the design won't let it. There's not full frame ;) (as in CHEAP)

Nice one Ro! Great Stuff, you'll never feel blue again! Cheers ADDA

Thank you Ro for posting this! I have a question: Regarding the corner absorbing devices, is it necessary to cover it with plastic first? Wouldn't it have a better to cover it with cloth only? Cheers, Laurent

Howdy L, Depending on it's function.... In general you will need BASS absorbers in corners. That means you have to "filter" out the HIGH frequencies or else you'll end up with a very dead room (yes, the cornerabsorbers WILL absorb all frequencies if ye only add cloth). The plastic only filters out the highs, maybe some mid-highs too. We used just a few broadband panels on the walls that are aimed to capture mid-low and all above. So, the plastic functions as a low-pass filter.. so to speak.

Maybe a silly question, but what type of plastic did you use? To cover the corner panels, that is? Is there anything else that can be used as a (cheap) low pass filter?

hello... Nice work.... I also had done a redesign.. But the fact I want to share is that I was hugely helped by Sketchup, 3D designing tool. Is anyone interest about it?

sure. please create a thread on this forum and post the SU file and any photos and jpgs per the posting rules.

Ding ding. Thanks for posting this.. this type of treatment looks really ideal for my space. The moveable wall panels on rails. How are the corner devices working?
