GIK Acoustics

So I just ordered some treatments. A pair of small diffusors and 3 panels. I still need to order a couple more diffusors and some corner traps, but that will have to wait a bit.

The guy at GIK thinks that the diffusors will make the most difference for me....we'll see. I figured they'd go on the side wall, but he said they need to go behind each main.

I'll post some thoughts when they get here.

I am real interested in your progress on this project. The more I read about the theory the more confuzzled I get. One guy says absorption on the front wall and diffusion on the back. The next guy says diffusion in the front. :shiftyeyes:

Some real world experiences would be most informative. :thumbsup:

I like Brian at GIK, he seems to really know his stuff.

Brian is who advised me to put the diffusors behind my panels....

[chessman]

Diffusors behind absorption panels?

[Jason]

Oops.....just realized how that sounded:fryingpan:

Brian suggested I put the diffusors behind my dipole panel speakers. The mid and tweeter panel are planar dipoles. These were his first recommendation. I'm getting the 242 panels to tame the room ringing I get at higher volumes.

[dvenardos]

What speakers are you running?

The whole point of dipoles is to get a diffused unlocatable sound. Diffusers working with a dipole makes a lot of sense. Though trial and error in the placement of the diffuser in relation to the dipole is needed.

Absorption works best on first reflection points to cut down on the harsh combing. This is usually side reflection and rear reflection. Of course peoples living rooms are rarely set up in such a way to allow optimal placement of absorbers and diffusers. Basically do the best you can with the room you got.

Well, I've put up most of the panels. I say most, as I'm waiting on 2 more diffusor's that are scheduled for delivery today.

First off, I'll say that they didn't provide the changes I was hoping for. I was really hoping they could help the room not sound as small as it is. They did help a little in this regard, but not what I was expecting.

I found that I needed to do some repositioning of the speakers. Before I had them toed in a little. Now I have them almost parallel with the front wall. I'm still experimenting here and may take a little while.

I can seem to hear deeper into recordings and can hear more of my system noise. It's not real bad, but something I will need to address next year....

:no pics:

[Jason]

lol....lemme get the other diffusors in first.

[Jason]

OK...just snapped a quick and dirty shot of the front wall. The panel in the middle is just sitting in the window sill.

Further observations....

I'm getting a little better left to right separation. I'm not real experienced in dipoles other than mine, but it seems the back wave that reflects off the front wall can blur subtle left-right positioning on the soundstage. Having the diffusors behind my speakers helped regain some of that.

I think I'm done with the room treatments for now. Might add some corner traps, but probably need to change subwoofers first. I can't get the pb13 in a position that it sounds good in with those traps. I'm thinking about getting a pair of Rythmiks to replace it, but plan to audition them at Danny's before I make a decision. Also, I need to get a new amp soon.
