Thanks Satie! But what is that "Limage setup"?? I couldn't find it with Google...

Sadie is spot on with how well this set up works, with the right room...scary good...when you get it right, things really open up and virtually snap into focus...
My room is 12'W X 19'-8"L...edge of speakers, (bass panel section), is 11-1/2" from the side walls...6' between the inside edges of the speakers...
Now this is what Sadie was referring to...the speakers are 8'-8" off the front wall...this equates to 43% into the room...from what was posted on this site, (lots of good stuff if you do a search on the HK/Limage set-up on this forum)...for this set up to work well the speakers need to be Minimum of 40% and a Maximum of 60% into the room off the front wall...
This virtually cuts my living room in half as far as usable space...since I am a single dude with no WAF issues it does not bother me in the least...my family thinks I am nuts, duh...and one of neighbors suggested I should buy some Bose speakers, because they are much smaller than my current speakers...well..we just won't go there...
If your room is a rectangle, you have a far-field set-up and don't mind sacrificing 40%+ into your room...this is the way to go...
Hope this helps...
thanks

The bass drivers appear (in the photo, anyway) very close to their side walls (T/in B/out?). Do you think you're getting any of that typical Maggie side-wall bass reinforcement from positioning them that way?
Come to think of it, all the glowing 3.7i reviews and it appears that no one has done a fuse by-pass (as of yet). Just imagine how much better they will sound after the fuses and their circuity have been removed. :-))
Hey Norm...
"The bass drivers appear (in the photo, anyway) very close to their side walls (T/in B/out?). Do you think you're getting any of that typical Maggie side-wall bass reinforcement from positioning them that way?"
YES...that is one of big benefits of HK/Limage set-up...As I have said before, without this board and Sadie I would have NEVER tried this set-up...it really takes a great speaker to the next level...
The fuse bypass is coming in the not too distant future...a friend of mine is going to do it for me, I am not the guy you want with a soldering iron in his hands...
Thanks

Well perhaps the side-wall base reinforcement is one of the big benefits of HK/Limage set-up, as you say. I've never had reason to explore it, however IIRC Magnepan recommended that bass panel side-wall juxtaposition ~20 years ago in one of their Tympani manuals.
I neglected to add a 'good-luck' for the fuse by-pass. I don't think I'd be so very good using a soldering iron either, even though I studied up on it watching Youtube tutorials. (IAE, after a soldering job done by one of my dealer's crew members failed, I didn't think it advisable for me to attempt ever trying it.)
We discussed it over the past couple of years. It is a placement method for room coupling to make the most of your room's walls - reflections and bass loading to bring about strong bass, warmer balance and outrageously expansive soundstagess while retaining image precision.
Mark Man Swamis cat and Wazoo all fell under the spell and so have a few others. Search in the MUG section with "limage" and you should have quite a few threads.
unique to a tympani, I placed the deep bass panel perpendicular to the wall with minimal spacing and the attached midbass panel is further out in the room. Both face stricktly forwards. I am trying a wide veriety of positionings with the mid tweeter and adjusting the crossover to match the different standoffs or arranging in partial or complete time alignment - within the limits of matching timiing with a 4X6 panel.
This allows you to capture the deepest bass room mode while avoiding the sidewall mode.
