LOL, I did a similar " time alignment ", just today.

Spent half the day moving my VOTTS and LPs, 90 degrees, to different walls in my small listening room, so the ALTECs will be equally corner loaded.

Since you are " experimenting" can I offer an inexpensive suggestion to you, that worked out quite well for me, and is easy and reversible 100% ???

Mass Load the speakers. Here is how I suggest to do it :

(1) Go to Lowe's, Garden Department. Find their concrete Patio Tile section, and ( initially, to experiment) buy ten poured concrete patio tiles. They come in grey and red concrete, I prefer the latter. The basic size I use most is about 12 by 12 by about 1.7 inches thick, and each one weighs about 16 pounds. Cost is either $1.37 a tile, or $1.87 a tile, a big BANG-for-the buck, cost versus weight !!

(2) So as not to scratch or damage the woofer's enclosure, place cardboard, or indoor-outdoor carpet on one speaker's top surface. Load just that one speaker, and A-B it versus the unloaded one. As you increase the weight, the effect will get better and better.

(3) Then, do the same Mass loading for the large horn you have, sitting on top of your woofer enclosure. LISTEN to that. Re-compare, the mass loaded, now in two places side, to your stock side. There should be better inner detail, and lower distortion, better overall resolution, on the mass loaded side.

(4) After you hear that A-B, get some more, and add it to the already loaded side, till it hardly makes any difference.

(5) Get the same amount of weight, for the other speaker side.

(6) I use early ALTEC 825 VOTT enclosures, which are only mostly 5/8th inch plywood, too thin. This mod, allowed me to keep the box 100% STOCK, yet have a sonic improvement, equal, or maybe exceeding, what bracing can accomplish. I stopped at 290 pounds added each side.

(7) I don't care how solid your box is, I am willing to bet you $20.00 this will improve your sound, and you won't look back !! Box first, horn second, then max weight, and then other side .

(8) Please, please, please, write back to me , once you try this, and tell me of your listening experience. I was SO HAPPY to have done this. My email address is above available.

Have FUN, I certainly am.

PS, Only AFTER this mass loading is done, Uncle Stu's Speaker Baffles certainly improved diction, on playback, but the mass loading is needed first, to appreciate the Uncle Stu mod.

Let me know your results !!! Thanks.
