Hi, I was looking at the Argent site and noticed that they have some optional setups. See link below. I only have three, so I tried two in the center and one behind my listening seat. I didn't care for them back to back, but then I tried them side to side. I now have them between and behind the speakers, with about four feet between them. Things seem a little more open, but it's too early to tell. So, do you guys have any unusual setups? I'd like to hear about them.

I have found that the Lens behind my seat, has solved some minor rattles that I was hearing at very loud levels. It was a lamp and something[?] else, I seldom heard it at my usual listening levels. It also seems like I can play the system louder without overloading the room. Actually louder than I care to listen. With my current setup, everything just seems more open.__________________

Hi Jeff,If you can make them easily, without the stands, try hanging one or several from the ceiling at the reflection point(s). Paint them warm/cool white and they would look like fluorescent lighting not turned on.

After seeing a picture of Ed Hsu's arrangement with his Maggies, I tried the same with my Acoustats. Narrow dispersion bipolar speakers pose different challenges. While the overall objective remains to eliminate image reducing reflections, this occurs primarily from the rear wave on large planars. Side placement has little effect.

You may have seen a photo on his website but it's of my system . Ed uses "noodle lens'" behind his maggies due to the live nature of his room.

This is true but strangely enough center placement makes quite an improvement in imaging. Glad to hear that you were able to benefit from my suggestions.

Sorry for the mis-reference. I try to credit the source for any useful audio into. Thank you for the inspiration! I made and tried using the third lens in the middle, but do not notice much difference.My listening space differs from yours. I use the golden cube ratio which places the panels much further away from the back wall. Also, my centered EQ rack likely performs some diffraction where it appears your back wall contains windows/blinds. Here's a link to the Cardas site you might find interesting.

I agree with the basic configurations mentioned by first two posts, I also find in my small/medium size room one lens in each corner improves the situation. None in direct rear of listener, none to rear sides of speakers. A very effective method for "calibrating" the system w/ lenses IMO is the XLO Test CD, Track 3, played on REPEAT - allows precise placement of lenses/Helmholtz resonators for obtaining the most natural presentation/soundstage.

I'm using 4 DIY room lenses. I have one outboard of each speaker, about 6" from the outside front speaker corner and angled toward the speaker corner. The remaining two are on either side of my equipment rack which is between the speakers. I've found that quite effective and they've been there for a fair while now. I've just added 2 of Jon Risch's "quick & dirty" bass traps to the corners behind the speakers and things are sounding very nice but I might start experimenting with placement again now that there are bass traps in the equation.David Aiken
I still like my current setup though I've heard that it doesn't work for others. I made a six tube unit that runs front to back between the speakers with the front tube lined up between the tweeters. My 2 three tube units are between the speakers and side walls. They run side to side approximatly 2 inches behind the line between the tweeters and toed in to match the speakers. I have never gained anything with a lens behind the listening position and don't like the sound with the lenses just outside the speakers as Argent suggests. My room is welled padded and tube trapped so that may be the difference. Experiment. Once you find the right position, you won't want to listen without them.
