Owens Corning 703 vs. Roxul Safe 'n' Sound?


I'm going to make some sound absorbing panels to place on the wall behind my listening chair. Owens Corning 703 and Roxul Safe 'n' Sound rigid boards are two choices to make them with. Anyone have experience with both, or even one?

Thanks auxinput. My ESL (old Quads) and magnetic-planar (Magneplanar Tympani T-IV) speakers don’t splatter much sound on the side walls, having the dipole null on either side and being pretty directional at higher frequencies, with the tweeter strips pointed directly towards the listening position at the mid-point of the opposite wall. They will be 5’ from the wall behind them, so diffusion should allow the rear wave to blossom well (one of the best things about planars imo), no need to absorb it. I’m not planning on getting actual real diffusers, having enough LP’s (about 3500), CD’s (around 6000), and books (if I can fit them in!) in racks to pretty much cover the room’s walls.

Thanks for the link Brad, but I don’t see it on my screen. Is it just me?! I need only to cover with absorption the 4’ x 4’ space behind my head on the wall which the listening chair has to be up against, unfortunately, to be able to get the planar speakers 5’ from the wall behind them, a higher priority to me than the lp.

Appreciate the help guys---Eric.

Brad, I would be curious on the link also.  It doesn't appear in your post but I have been looking for DIY panel material.

I'm no DIY'er in general but had a decent outcome making 703 panels.  They helped tremendously in my room to kill the first-reflection points.  I've got a total of four 24x48x2 panels in the room and things are sounding great.  I do think that more panels would be too much.  You can see a pic of them in my system page.

Hi Eric

My Room A is enclosed on the outside of the drywall with Roxul Safe N Sound. The Ceiling and two walls. This was done to insulate the room sounds from the rest of the house. The other two walls are against the house walls with regular insulation on the other side of the drywall.

Something to consider, just throwing it out there.

Curtains of various heavy and light materials work and look good. I am using them extensively in the adjacent room. You could hang one ceiling rail behind your listening chair. Curtains, offer the extra advantage of hiding extra speakers. :^)

You could also use one Magneplanar Tympani speaker behind your chair right now - try it. They absorb. I know guys with Acoustats doing this.

Cheers Chris
