Been building this one for at least 60 years, and because I'm now 75, I think it'll be my last.
The room used to be a flat-ceilinged 21x14-foot living room, but in 1982 I turned it into a 21-foot-wide, 19-foot-deep music room with a ceiling rising from 6-1/2 feet at the front wall to about twelve feet over the listening position which is about four feet from the rear wall. It's difficult to describe, but it has not much surface area parallel to another. Its negative characteristic is its almost squareness, which creates a HUGE roomnode at 28 - 30HZ. Here are some OLD pics; PLEASE try not to laugh at some of my old stuff.
Looking at the back wall and left-rear corner.
Left wall and corner.
Back wall and and non-90-degree rear corners.
Right-hand wall and entrance. The speaker at far left is one of my DIY monsters, long gone. It didn't take me long to determine I knew approximately nothing about designing speakers.
The room now has two LARGE bass traps, at the top-rear and LH upper corner, and two three-by-five-foot-by-six-inch basstraps/dampers on the front wall behind the speakers.
Speakers are Serenity Acoustics Super-7s, hybrid dipoles; lots of details here... https://www.audiocircle.com/index.php?topic=141060.0
(Please note that the beginning of that thread is now four years old.) The speakers sound EXCELLENT, especially when driven by my slightly improved Atma-Sphere M-60/3.3s.
More later.
