    If that back wall was completely open, I agree some treatments behind the speakers would probably be required given they are so close. I've tried it. I still have rockwool panels leftover, but it really does kill a lot of what makes the dipoles enjoyable. Or it might be just because I am used to it, since the Maggies replaced a pair of Definitve Technologies bipolars before them. Given they are kind of closed in to begin with I don't think the additional damping is needed. YMMV.

    12 feet from the back wall LOL. Room is only 14 feet wide. I've spent many, many hours playing with speaker positions. It's all a compromise of course, but I think where it is is pretty much the best (for me). I have plenty of hand drawn maps with various distances and opinions. They are now in the spot I have marked on the carpet with tape so I can put them back exactly there. If I move the Maggies out further, then I have to move the subs out further because otherwise they will be behind the panels. And moving the subs out further hurts the bass. I find the relationship between the subs and the Maggies is more important than the relationship between the Maggies and the wall. A lot of people think traditional subs don't blend well with planars. I'm actually quite happy with how it has worked out.

    Of course, I'm effectively listening to them in nearfield in such a small room. Some people hate planars in nearfield. Again YMMV.

    I may just be a horny college student, but women (and boobies) are always better than audio.

    Women and boobies don’t tend to come as sepetates according to my experience, the right woman (mark the singular) beats most of all other things.
    Am I surprised that @restrav3 prefers tubes to boobies? Looking at his avatar I guess tubes may be more useful to him.

    My neighbor asked me if I wanted these JBL112 or if I could sell them for him.. Got the day off today so having a nice morning of ABing and am pleasantly surprised by these old school jbl. These were an upgraded version of the JBL 100 with apparently beryllium coating on the tweeter and a proper cross over.

    Exceptional condition given they are nearly 40 years old. EC studio driving them loud no problems. Surprising at 89db at 8ohms

    My very basic attempt at measuring. L+R. Those who have been following my room treatment will note the large sub 100hz null is all but gone.

    Only just noticed this, but is that aircon mounted at a wonky angle or is there some weird optical illusion thing going on? It doesn't seem to run parallel to the ceiling.

    Good eye, but the roof is slanted.

    Been wondering how I'm going to mount the projector, screen, ceiling panels and upgrade lighting with this slope.

    My triamped Tympani IVa's, in split configuration (bass panels behind the mid/tweeter panels). I repaired them and plan on upgrading the midrange drivers, so their fabric is off . . .

    My setup.

    JBL LSR32's, powered by an Adcom GFA-5800. The Denon AVR is only used as a preamp (for now).

    Atlantic Technology 10" sealed subs, although the right one amp is not working. I think the amp went out.

    (And yes, that is a Laserdisc player up there. I'm a sucker for vintage technology. Also in there is my Pioneer DVD-Audio/SACD player.)

    I do love the JBL's, even if they are "studio monitors". Detailed, spacious, and not like scooped old-school JBL's. The big 12" woofers are also warm and punchy, but not boomy - very controlled.

    My experience entirely. I tried absorption behind my IVa's and the imaging became very precise but dead, like what you hear in the studio. So localization was impressive, but the sound lost its mojo.

    Two channel stereo really needs help from room reflections.

    I've also tried QRD diffusers at the first reflection point on the front wall and they make the sound spacious, but in my installation, I found them a bit too phasey as I moved laterally. It may just have something to do with my setup or diffusers, because they seem to be the most popular room treatment for dipoles (some use skylines rather than QRD's). Where I did find the QRD's worked great was in the front corners -- I have some 703FRK bass traps there and when I put the QRD's in front of those, everything just clicks, spacious, deep wall-wall imaging with excellent layering but no sense of confusion. This with the mid/tweeter and upper bass panels about 5-1/2 feet from the wall, and arranged so that the reflected backwave can get around both sides of the mid/tweet panels.

    Projector mounts allow you to adjust angle.

    Do a fixed screen to avoid waves over time.

    I too dislike diffusers at the first reflection point. My preference is an absorber. QRD lining the wall behind the speakers would be awesome.

    1st reflections should be absorbed, rather than diffused, as they contribute to tonal balance, rather than imaging. Classic studio construction usually puts diffusion behind the listener.

    Cool to see some more L112's. Those white grill cloths are shaggadelic.

    The tweeter diaphragms are linen/phenolic and coated in aluminum. More pleasant and forgiving (i.e. rolled off) than the later ti tweeters but the aluminum coating tends to flake and peel off over time. Can still source replacements at a reasonable price though (JBL 035 tweeter uses the same diaphragm and goes for much less than the 044).

    Sorry for the OT.How or in what way does it affect the tonal balance? I have absorption myself, but have also read people recommending diffusers.
