I tried the Cardas formula and it seemed to work fine. I’m always trying any formula I can. The one that worked the best for me, ironically, was a formula on YouTube (can’t remember the source) for quick decent sound for most rectangular rooms with speakers against the short walls. I thought...what the heck and it yielded a better result. It was suggested that it’s only a starting point and to tweak from there.
It’s 1/5 width of room to the tweeter from the side walls.
And 1/5 depth of room to the tweeter from the backwall.
Next, experiment with seated position and speaker toe-in.
Best result I’ve had is nothing between the speakers. I moved my rack to the side wall.
This helped imaging immensely. It is said that a lot of the imaging/soundstage is killed by stuff between the speakers.
It sounded much better than the sound room at Upscale Audio. This room (no longer in that house) crushed most tailored sound rooms I’ve experienced. It also had an acoustic ceiling made from concrete (no asbestos) and wood floors. One wall was heavy stone so I attached high relief wood carvings (and cuckoo clock) all along the opposite wall to mirror the stone wall as much as possible.
I miss that room.
