I will toss out there that I recently "discovered" my M&K's "Tripole" mode and that has made a big difference. In my case, more output from the monopole portion "goes over the head" of the near seat to the far seat, and correspondingly reduces the dipole component of the speaker's output (and the level of the surround at the near seat). Things are still peachy in the center seat with a touch more localizing of surround content, but now the surrounds are more enjoyable at the left and right seats as well.

Theaters have line arrays for very good reasons of audience coverage. But I'm not out to replicate theatrical sound in my home theater. I want to hear the soundtrack as cleanly and clearly as possible, in a single, seamless, contiguous space-time continuum. I find 7.1 works really well, direct radiators all around, for movies and also for music, which is the majority of my listening.
I like the idea of the Tripole. Wouldn't it be cool to have a surround processor that could feed the diffuse parts of the sound to the dipole drivers and the direct sounds to the monopole?
Interesting discussion tucked away in the Master acoustics thread...
When I bought my set-up Dec-2007 seemed most people were still recommending dipole surrounds, so I got mid-level Paradigm Monitor 9 speakers for my 7.1 set-up, with (4) of their ADP-390 for side and rear surrounds.http://www.paradigm.com/products/par...series/adp-390
Now, my brother inlaw just outfitted his HT with Monitor Audio Gold series, and his surrounds are their GSFX surrounds, which have a dual mode configuration (dipole or monopole) so you can pick and choose.
They even state "The GSFX is ‘ambidextrous' meaning the speaker can be configured as right or left "handed" during installation (via front panel switch) so the polarity of the front speakers is in phase with the GSFX surrounds. "
You can see the switch on front face in this picture:http://www.monitoraudiousa.com/produ...x/your-speaker
So, where I'm going with this is from Jan-2008 thru Feb-2011 I did not have any acoustic treatments, now I've added side/ceiling RFZ panels.
Nothing specifically on the rear portion, so I still have that similar ambiance from the dipole config, but I have to wonder if I'm "missing something"..
Seems like most of the dipole manuf should at least add a switch like Monitor Audio/others have done, and let the end user choose based on their preference and listening material.
I've toyed with the idea of replacing the rear ADP-390's on the back wall with the Paradigm Titan Monitor, keeping the side surrounds as ADP-390's.
Or.....re-wiring the rear ADP-390's so instead of the sides being out of phase and creating a null along their axis if both are in-phase then that would give more "forward" coverage, in effect like a monopole switch on the Monitor Audio GSFX's.....
yea, I should probably move this thought to one of the speaker forums or audio set-up theory forums....but it was brought up here and got my mind churning...
