Room is acoustically treated on walls and ceiling. 99% completed. Not sure if I’ll every finish that last 1 percent. Built the room 25 years ago. Did acoustical upgrades the last 2 years. The main support for my house runs through my room. I angled the drywall over the support to avoid 90 degree angles. Turn the ceiling into a acoustic bass trap.
Built my own 20 inch Bass Traps.
Main cables are MIT Spectral Grade or CVT Type.
The Janis W1 subwoofers were purchased in 1983. Great subwoofers for music, not for HT.
