my spare bedroom plan

hey, my first post so please go easy on me... first off, im 26 years old, from Finland, it-specialist by trade and music as a hobby. started by playing violin at a young age, progressed to the dj world and composing tracks from that. I also build stuff and help friends to record their stuff. so i got an apartment loan, im going to buy my current residence and I have a spare bedroom to spare for the music that I do. Im planning on starting a small renovation in july when the apartment is all mine. the room is 4.25 meters long, 3 meters wide and 2.60 meters high. there's a big triple window on one of the 3 meter walls, 2 doors for the hall and one for the bathroom. picture is included. my questions are, how do i tackle the window? im having plans about a heavy theatre curtains (i could probabbly squeese double curtains in there) and standing rockwool panels. any suggestions? one thing is that because of the window and the 2 doors, im able to superchunk only one corner of the room. any suggestions about the other 3? free standing superchunks? id' really like to have a sub in the monitoring available because of the music that I do has heavy bass... any suggestions how to handle the parallel walls? I have the basic idea about acoustics, but I guess im just asking for a second opinion... maybe we'll start with these right now. thanks for anyone who will find the time to help a noob.

here's a picture of my initial plans. superchunk on one corner, angled walls and a heavy curtain. a couple of free standing panels...

the heavy bass is going to be a problem in such a small room with doors and a large window. you'll probably want to block off the window with something more substantial and double on the entry door.

thanks! that looks sweet! the window is a problem, i know. but that room is about as good as it gets. the double hanging curtains, plus standing panels don't help at all? i mean, id like to have natural light from time to time and maybe some fresh air aswell... :)

I don't like those off-centered, nonsymmetrical room designs. It's mostly an aesthetic thing for me. I'd keep the room symmetrical. Face the window, and have large curtains you can draw if need be. Put superchunks on the wall/ceiling corners. Use John's angled slot resonators to break up the parallel walls. Float a ceiling cloud, and put as much absorption on the back wall as you can.

mans best friend, ikea.

edit. im going to make free standing bass traps to the window corners with these...

so im off to get material this friday. im going to make one superchunk, angle the back wall a bit, stuff it with rockwool, panels for the doors, plus a big panel on hinges to create more trapping to the doors, johns side wall units on both sides, ikea bookshelfs to the window corners filled with rockwool, one panel on rollers in front of the window, molton fabric for curtains and a ceiling cloud. maybe some movable panels if i get leftovers. i hope i can get some pictures... one question about the back wall, to really get some angle, do i need to make like some plywood angled-rockwool and fabric or is rockwool-fabric enough to get what i need?

start with just the cloth covered versions. if you find you have problem frequencies, you can convert some of it to slat resonators targeting the problems.

thanks! should I still go forward with the sealed box though? how should i do the back wall? just stuff it?

i'd skip the sealed box unless its something within your budget and readily done. I'd stack the insulation if possible and also putting it in separate sections will keep it supported - you can also put in some strapping or string to keep it in place and lined up neatly.

thanks, im going to do some free standing panels, so i can move them if needed. i'll put up some pictures when i get something done... :)

ok, friday a friend of mine came and we went out and bought 10 packs of paroc cos 5 rockwool, 2" per panel, 30 ors o meters of 10mmx10mm thick wood, and a lot of random smaller wood to make backing frames for the rockwool panels. and a lot of random stuff. today we got the back wall skeleton almost done. i don't have a camera im afraid, i'll try to get one as soon as possible. im a bit tired. sunday is another whole day to work on stuff, monday it's back to working after work.
