If understood correctly (through Google's translator), the multisub arrangement simply had all subwoofers active at front and rear walls. A more instructive comparison would be with 'an optimized' multisub setup with 3-4 subs placed around the room with gain/delay settings for each.

7 feet = 160Hz FWIW

did you derive that from seven feet at 2700 degrees?

that is interesting, I cross my woofers at 200, yet due to the way I have differently measured (and hence corrected with the deqx, which 'fixes' phase and delay) I have been wondering about the match at the crossover point.

Have been wondering how to accurately measure the phase/time delay at the crossover point as I can manually compensate if I know the figures.

BUT it seems from the article I should not worry too much? (as I say, I no longer fuss at the very low frequencies, but was concerned at the effects at 200)

New Abbey owner

I was wondering if I could get some set-up advice from Markus. I recently bought 3 Abbey 12's from Earl (and picked them up) but still a little unclear on the best angle to set-up the speakers. I know they are not designed for on-axis listening but didn't know the best direction to point them as far as the right and left speakers. Also, since I am using the 3rd for a center channel, it would appear that would have to be on-axis at least to the sweet spot (or maybe not). Since i know Earl is at ALMA an CES, then I thought I would post here. Tried to email you Markus, but since I am new to the forum, it requires a few posts first. Appreciate any help.

I would agree with Marcus angles, but I might try and move the speakers a little further appart. The distance from center to L/R speaker should be "about" the same as the distance to the side walls. So take the room width, divide by 4 and thats the distance to walls and center speaker. You can move the speakers a littler farther out than that, but I wouldn't move them closer.

At what distance (screen width, listening distance, L/R separation) would you (Earl, Markus, anyone) consider a center channel to be beneficial or essential?

Also, is it only effective for movies or is there also a benefit for regular 2-channel stereo recordings?

I would say that a center channel is always a benefit if the center signal is available or correctly derived from the L/R signals.
