One easy way is to just suspend them with a couple of elastic bands. For my 2x4 panels I cut a 16" circle to sit on top of my H frames, attached a 1x3 frame, narrow edge toward the panel about 15"x48" so that it doesn't show. I put short screws into the back side of the panel 1" below top edge 15" apart, 2 more near top of the frame (longer screws) small elastic band about 1" in diameter lets the panel hang free and nothing shows. EPS is so light that not much is needed. Even the speaker wire holds the panels from swinging. Several ways of doing it are shown in this long thread. I prefer not to restrict the movement of the panels. I have in the past attached them to a frame using pieces of foam backer rod which did restrict movement a little but it didn't seem to be a problem. I haven't worried much about a permanent arrangement because the experimenting becomes an addiction. My wife is used to it and likes the sound of the panels too. Rich I think your chances of staying off the shit list are slim at best. It sounds like you are getting hooked too.
My 2'x4' panels are 3/4" thick. It's messy but sanding off the surface skin left by the hot wire cutting and Sedges PVA treatment will drastically improve the noise of your big panels. They will sound much more natural as well. That skin has to go if you want to hear what these are capable of. Just coating them as is won't do it.
OB Newbie - still like your XPS panels? Are they worth a try or is the muted sound still there?
The birch panels are only $10 each and the 4 X2 at home depot are similarly priced (and if you don't cut or sand on them they can prob be returned if they don't work out).There were some more details on the different EPS vh equivalent grades availavle in the US on pages 52 and 53 but I wasnt able to find a conclusion (ran out of time). I also think some people use hard eps for surfboards.

I hear you on the voids. In regards to the special wood store I found the quality was much much better and I was surprised with the low price... but maybe it is the voids that make it sound better ??? Will try to braze the thinner panels. Back to the EPS hunt
Has anyone tried foil-faced poly isocyanurate board? I haven't looked at specs but it seems to be more rigid than XPS and lighter. Commonly available in the US in 1/2" to 1" thicknesses....
Yes, I had some larger scrap pieces at home several months ago. I didn't know about the re-skinning method at the time so I only played them as-is. They didn't sound good in stock condition - very muffled - kind of like you would put a pillow over a speaker. So I abandoned it quickly. But perhaps Sedge's trick will make them sing. I don't have one at home to try.
VH EPS AND "THRUSTER REVIEW"Thrusters are mounted in number one position as per Monacor placement /recommendations.First thing that becomes immediately noticeable is the significant increase in volume/efficiency of these new tech. exciters!!!!Second is the fact that the VH EPS available here in Western Australia has no "skin" ..........it just has a finely textured surface that has no shine or anything that I can tell that resembles a surface that needs to be sanded and replaced by PVA glue.Third point is that as expected- the 6X2 sheet at 20mm thick is far, far more rigid than standard EPS at the same thickness.The sound is very interesting to say the least. The speakers totally disappeared as each track or radio program changed. However, never once was there any question as to what was in the left channel, centre or right channel.Depth was truly amazing, as was the obvious acoustic venue or closed in studio miking which plagues so many recordings."Dynamics"?.........WOW!!!!!.........absolutely the best I have ever heard from a DML!!!.......don't know if it's the thruster exciters or the more rigid panells? The PERCUSSION XX recording mentioned in one of my last posts is jaw dropping..........different!......strangely so.....very weird, yet so compellingly REAL!!!Top end is very natural but not as fierce or prominent as the thinner EPS with standard exciters. Only burn in time will tell if this area changes or not as it could be the exciters or, once again, just the fact that a thicker panel is being used?Detail?.............it's all there........trust me.Mid-bass?.........lots of tonal colours and contrasts........truly outstanding, massive dynamics as already mentioned.Low bass?........ Jury still out on this one.........panels are free standing and not mounted as yet.Rob.
Local speciality lumber store in Indianapolis that carry a lot of different kinds of wood (including many excotic hardwoods), plus they are super nice and helpful (even had some suggestions when I mentioned what I would use it for). I'm guessing there must be similar lumber stores in most major cities http://www.northwestlumberco.com/
