That's a good estimate, actually, particularly given the distortion from the panorama. Actually in this photo, the left woofer is about a foot closer than the right one, a situation that's less than desirable, but there's a radiator in the way:
I originally had it equidistant with the other woofer panels and out a bit from the wall to allow for the radiator, but it got in the way of the projected image so I had to move it to the current location when I installed the screen.
I really need to move that radiator around to the wall behind the speakers but the plumber isn't sure if he can do it without breaking into the wall, which I'm not super eager to do.
Anyway, currently the MT panels are closer to the woofers and front wall than in the panorama, I've been experimenting to see if I could get them closer to the wall with the diffusers in place. When I move them I try flipping the phase to see if it's better or worse, the XO is about 250 Hz so 2.5' is 1 wavelength and a flip isn't required. But this is just a temporary setup, now that I have the second amp in and did the A/B experiment I'm going to bi amp with the MiniDSP and use that to bring the woofers into time.
Follow Ups:
I'd be concerned about the 'health' of the speaker having it seated so close to that radiator, (while it's hot and running). It's been a very long time since I've been exposed to such a radiator, but IIRC at times it even released small amounts of hot steam!
I was concerned about that as well but when the heat came up, I felt around the radiator and it wasn't that hot near the speaker. And there's no steam because I made an enclosure for the vent that has a plastic tube that disappears into the wall!
I still want to move the radiator but at the rate the plumber comes that could take a year or two . . . by which time I may have another solution, which is to join the midbass panels to the mid-tweet panels and then join the low bass panels together on the right side against the wall where the right hand bass panels are now.
