Finally Ordered Acoustic Panels
After months of going back and forth on the return on investment for acoustic panels, I finally broke down and ordered some today, I have tweaked my system in so many ways imaginable, the biggest improvement may yet come from room treatments.
I ordered two sets of the Impression Series from GIK and 10, 36"x24"x2" acoustic panels from Acoustimac. I wound up ordering the sample kit from Acoustimac to be sure which colors and fabric I wanted. I was set on the suede and executive fabrics, once the sample kit arrived, the DMD fabric was the best of them all IMO. I'm really looking forward to installing these panels and seeing how well they work. Now the wait begins!

When placed appropriately, you will be very satisfied with the results of room treatment. I have a mixture of ASC Tube traps and acoutimac panels and i am very satisfied with the end result. Congratulations and keep us posted on your thoughts.

When you get those placed such that they attenuate the primary reflection points in your room (relative to speaker and listening position) you'll slap your forehead and say "why didn't I do this a long time ago!!??"

You can use a simple mirror to determine your first reflection points for your panels. Just slide along the each side of the room to see the reflection points for each speaker. You will note that the left and right speakers on each side of the room have their own respective reflection points, and ideally, you have a panel at each point on each side for each speaker. Regading the panels you ordered from AcoustiMac, the "acoustical panels", are sound-absorbing, and are best for attenuating and mitigating slap echo, but they won't do anything to add diffusion, and thereby life and sparkle to your room. I've found I don't need much of these as my space is pretty heavily furnished (see photos below). I do have a panel from AcoustiMac on a wall that separate my living space from the kitchen area and above a large picture window that is an "outside" wall. I'm going to go out on a limb and guess you will find the GIK Acoustics Impressions panels will provide the most notable and enjoyable improvement. I was kindly gifted 8 of the GIK Acoustics Alpha 4A panels and 4 GIK Polyfusors by a local AA member, and its turned out the Alpha 4A panels have brought, by far, the biggest improvement. I originally put all four Polyfusors into my well-furnished "room" and it sucked all the life out of the presentation. So, now, I only have one, in 1 corner of the space. The other 3 are presently sitting unused in the spare bedroom. The Alpha 4A panels, OTOH, really bring a very nice improvement, and I've now got 5-6 of them in the room. I'm still playing around with placement with some of the remaining 4As but I have two along the "front wall" (which in my case is a half-wall, one at a reflection point in the window behind the couch, and two in the corners between the outside wall (near the big window) and the corner of the half-wall on top of the REL sub. You've probably read what the Alpha 4A and Impression panels do, and I really like the improvements they bring. They are intended to provide both some diffusion and liven up a room, and they do this in a very nice and natural-sounding way. They make the presenation more spacious, lively, and "focused" in a very good way, and they also improve the imaging of the stereo sound field. There is a technical paper on what they do on the GIK web site on Decoding Diffusion: https://www.gikacoustics.com/decodin...tic-solutions/ I'm using the linear 1D panels, 4" deep as that is what I was kindly given by Keith. Here are some pics to show you how I am using the Alpha 4A diffusor panels. The main rack and the Harbeths. You can see two the panels on the half-wall behind the main rack. A wide-angle view, showing the panel on the left at a first-reflection point. You can also a see an AcousticMac acoustical panel on the wall near the celing and above the couch and window. .

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.

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.

Yesterday I brought in two more Alpha 4A panels and set them in cater-corner at the corners of the front (and side walls).
As the 4A panels are 4" deep and have acoustical rock wool fill, they also function as a bass trap.
