Sanders Sound Systems - electrostatic

I think some of us feel that it is tad disrespectful to keep posting pictures of Acoustat speakers and talking about your perceived impressions that Acoustat are the one and only superior electrostat speakers in a thread that is supposed to be about Sanders.
Great thread, I was wondering if Roger has any thoughts or preferences on diffusion behind his speakers?

There is an article on his website discussing that. He suggests none, rather adjusting speaker placement, IIRC.
FWIWFM, I prefer some sort of treatment behind any bipolar speaker as I have almost always found it improves the sound and imaging by decreasing filter effects from the back wave. I have gotten away without in a large room, with much fiddling, but unfortunately my present room is fairly small and thus heavily treated.

Absorption or diffusion?
I've not been able to get absorption right, dulls and compresses in the worst way imaginable. I must be doing something wrong, a fair amount of people swear by it.
The limited diffusion I've been able to manage retains the liveliness and energy without confusing the sense of openness.
I've tried absorption behind my Innersound's several times and never liked it. I'm using plants for diffusion behind them now and love it. I did have to play around with placement to get the best result.
With that narrow room and speakers rather close to each other I'd imagine that you have a very solid center stage if not a wide one.
If you want to get a ridiculous amount of center stage, may I suggest removing that reflective picture from the wall and hanging a tapestry with sound absorbing material behind it? The tapestry need be no wider than a hallway runner to have an enormous affect.
I could try that as I have some spare 704 owens corning insulation. If I like it the tapestry would be a good idea to cover it up.
I would like to try some diffusion panels in the same spot as well but I would have to buy some first.

That could prove to be an interesting experiment.
My personal preference (M/L not Sanders or Innersound) is diffusion behind the speakers and absorption between them.
Thanks for the idea. It is certainly worth a try. My Innersounds are beamier than your M/L because they are flat instead of curved but there could still be some correlation.

I have done both but currently have only absorption. That is OK with me, as the image is solid and any ambience comes from the recording and not the room. It is not the sound a lot of people like, however, and different people have different tastes. Diffusion generally costs much more but gives a more satisfying result to most people because of the extra sound energy bouncing around. An intermediate approach is to use absorption panels with a membrane on the front side so only LF signals are absorbed.
Planar speakers tend to act like line sources above the bass region so actually do not need a lot of room treatment. I prefer to kill the back wave with absorption directly behind, then use little treatment elsewhere. At least given a good-sized room. My current room is small and live, with a couple of closely-related dimensions causing some ugly room modes. For that reason I have treated the heck out of it.
I tried some absorption in the middle and it is a very nice improvement. I had tried that before but without the diffusion behind the speakers. Thanks for the tip!
I bought a 5x7 carpet to cover up the 704 insulation.
Hi guys, I just found this particular discussion and wanted to toss in my two cents.
There is a new whitepaper on website regarding this very topic, if you'd like to read it. http://www.sanderssoundsystems.com/technical-white-papers/room-acoustics-and-treatment
cheers,
Angela
p.s. Fall has arrived in The Rockies!

Don-What is the weather supposed to be like next week for RMAF? Fall is here too in Indiana. Our leaves have turned colors and are starting to fall.
I haven't seen any trends that far out and they would be wrong anyway. I left the house this morning at 35 degF and it hit near 80 degF this afternoon down here in town (a good 1000'+ lower than my house; Denver is lower still). The mountains make it tough to predict with certainty. Plan on cool nights and decent days, but watch the forecast as sometimes we get a pretty good snow in mid-October.

We are supposed to get a little snow at my house this weekend but it won't last. Be snowy Saturday and sunny Sunday.

let's hope the weather gets it all out of its system this week. It won't be a big deal for anyone coming into Denver as snow this time of year only sits on the grassy areas for a few hours and gone. I just hope it is clear blue skies for all our visitors to Colorado.
