Chakster, martinman has a much better room for bass than you have. Equal dimensions are the worse thing you could ever have. No amount of room treatment is going to deal with the long wavelengths. 100 Hz is 10 feet. Room treatment deals with frequencies above 200 Hz at best and it is very important but, for bass it is the room size, dimensions and construction that matter most. The single best way to deal with room nodes is multiple subwoofers. Martinman’s integrated has a full 2 channel 2 way subwoofer cross over built in and an excellent phono stage. The Hint 6 may be the absolute best value in audio amplification out there.
Rectangular room is indeed better. But you guys are crazy about subs!
My room is not square, so the given size is simplified, actually it’s irregular shape with cut corners and a door on the back wall that can be opened while I’m listening to the music (behind the door I have more space for low frequency to be vented out of the room to the huge corridor.
Anyway, maybe I will start a separate topic about room acoustics. I have room a treatment and working on it for better results. But it’s always a compromise between interior design and sound. Actually I have a second (rectangular) room in my flat and my old system was there. I prefer my bigger room now and it’s closer to the square shape, but not square.
Actually my room is on the boarder of yellow and green zone HERE>, so I'm good @mijostyn
