Nice setup, Stephen.
How do you like what the corner-mounted Alphas do?

My room has some echo issues and it’s lively in terms of the higher frequencies which I am trying to tame. As it relates to putting the diffusers behind the speakers, is there an optimum location? Should they be higher, lower or the same size as the speaker? Sorry for all the questions, I want to make sure I am doing the right thing the first time around. Thanks.

Since listening rooms and circumstances vary widely, you might consider emailing GIK with photos and a diagram of your room with all applicable dimensions (length, width, height) to get their take on the "best-fit" acoustic treatment for your particular situation.

I like them; the more I put in the listening area, the better the system sounds. I haven't done any experiments yet to see if positioning them differently impacts their effect in a particular manner. I just put them in the night before last, still playing around. Cheers, Stephen

Ha! Thanks, Ed!

The absorption panels primary function is to reduce slap echo by acoustical damping, so you if you have some echoes, then you can place some at various positions in your room. You can also intersperse them on side or back walls in between the diffusor panels if you wish. With respect to positioning the Alpha 4A or Impressions series panels, I put mine pretty much behind the Harbeths, as can be seen in the photo. I'd probably put them a bit higher, but I can't as that is the height of the half-wall behind the speakers. They also can and should be placed at reflection points. With respect to number, I'd just play around and experiment. GIK says that the more you place in the room, the better it will sound, and I'm inclined to agree with that. My limitations right now is that I'm running out of places to put more in in my unusual and unorthodox listening space. Also, GIK has free advice, so you can call them for specifics on mounting and placement and positions. They are very helpful. You may want to consider ordering your acoustical (damping) panels as well from them just to make ordering and shipping more straightforward.

IMHO if everyone placed a few Stillpoints Aperture II panels in place of many of the ones shown here you will experience even greater sonic mastery. They are down right spooky.

The GIK Acoustics diffusors, at $79/each are 1/10th the price and work really well. I've taken the "Schiit Audio" approach to acoustical treatments. Very high quality products sold online direct to customer at great prices and backed by outstanding customer support.
