nice job will be doing something similar soon i hope.

Thanks for the how-to

is there an approximate cost you could guess for constructing each panel? Just in case anyone wanted to consider building something similar of their own.

more analog, more sidechain

This is really important to me ATM... the polyester batting: Where did you get it? Would you describe it as more 'layered' or more like wadding?

Thanks!

Nice.
I've given up on making my own panels. It's impossible to find dense enough insulation here in Sweden.
I suppose I could just use fluffy rockwool, but I think it would be a waste of money.

great. we need more info and others solutions here, im about to do something similar but im not sure what yet. as my "studio" is just a desk in my livingroom it needs to look good too. anyone else have some nice pics and stuff?

You know, I didn't keep track, but I should have.

Here is a very rough approximation:
-Each Fibrex 1240 rock wool insulation panel (2'x4'x4") cost about $16 USD each. (about $250 USD for the entire project thus far).
-The burlap cost about $10 per panel (when ordered online). I picked up the white burlap from a local "Hobby Lobby" store which was dramatically less expensive.
-Fireproofing solution cost about $50/gallon (after the $15 or so shipping charge) - I've already gone through 1.5 gallons. I expect another gallon will finish me off.
-$50 for all the hardware hangers, chain, etc. (for all 16 panels I built)
-$30 for the all the MDF material (for all 16 panels I built).

The superchunk bass traps will be quite costly by themselves as I need to buy 16 more rock wool insulation panels for it.

I also have a table saw and pneumatic stapler and finish nailer that I used quite extensively.

Joann's Fabrics online: http://www.joann.com/joann/. The stuff I bought is here: http://www.joann.com/joann/catalog....PRODID=prd14620

Its in a giant roll that is layered. It is easily torn with the hands - no need for scissors. Any piece that overhangs can easily be ripped off.

Sweet, thanx for the post, some good info there

it looks really nice mate. I've been looking into treating my room with some makeshift boards also. im just wondering if there is any particular reason why the monitors are at an angle. I am no acoustic engineer, but i would have thought that angled placement would result in a distorted stereo image. also, what about the corners of a room? again, im not a connoisseur but i ve heard that the corners of rooms can be a source of many acoustic problems. ive found that different people say different things when it comes to acoustic resonance so your opinions are much appreciated.

look forward to seeing the developments.

very few two way monitors are designed to be put on their sides like that, but some are. it's also not good to have them as far apart as he has them, as he is not sitting in the sweet spot (which would be a meter or two backwards). in terms of tilting them down, the only bad thing about that is you get more reflections off your desk... but, that is the design of his desk.

life is about compromise!

i think you will find alot of pro studios don't even actually have their speakers positioned properly. with old mixing consoles it was easy, but with computer screens and everything else getting in the way, times have changed.

on his page, he said he's got some chunk basstraps in the making. safe to assume hes going to put these in the corners.

echosystem answered most of the questions already, but I'll chime in as well.

If by angle of the monitors, you mean why are they facing inwards towards me? They are near field monitors so they should be pointing directly at my head - where I sit. The corners of the room will be filled in with solid Fibrex 1240 rock wool insulation in the near future - superchunk bass traps.

With regards to some comments echosystem made. These are older Alesis Monitor One monitors. The logo on them is actually positioned correctly when they lay on their side, so I assume these were meant to be laid on their side like this. This also allows for both the tweeter to be at ear level - which is ideal since the higher frequencies are more directional. The speakers are tilted down to help 'point' it at my ears.

The reflections off my desk should not be of a concern. The time delta between those sounds that are direct vs. those that bounce off my desk should be insignificant. They are so close, I doubt the human ear/brain would count them as two separate sounds (just a guess).

The ideal sitting position is 38% of the length of the room - which is where my head is located within the room.

But, you hit the nail on the head about many things I had to deal with - compromise. My room was only so large so I had to make do with what I had.

In any event, the room sounds so much better than it did before. Now, once I stop building all this crap, maybe I'll have time to actually do some music again. Hopefully, my new productions will translate well outside of my studio. Most of my productions before translated quite muddy outside of where I was mixing - I had no acoustic treatments at all.

If you guys want a good source of info, head over to http://www.johnlsayers.com/phpBB2/index.php. This is where I learned everything. If you want a good Acoustics 101 training and how to place/build panels in your studio, go to http://www.ethanwiner.com/acoustics.html - tons of info there!!!!
