The 5 stages of making a bad audio purchase

@glupson My listening room cost about $155-165,000. It has 16" thick, acoustically engineered walls per AcousticFields designer with activated carbon filtering, a 3000 psi 12" thick steel reinforced slab, 2 ton low noise HVAC, dedicated power panel with 10 circuits with 10 gauge wiring, 90 oz. plush carpet, 3/4" cherry paneling. Synergistic Research blue duplexes for audio gear. The interior walls are set on a 12" plate with 1" MDF, 1/8" Acoustiblok vinyl sheathing, 3/4" MDF, 3X12 studs, alternating 2X12 and 4X12 full height blocking, sandwiched in the 2X12s are 4’ X 12.6" four 4" thick chambered carbon filters, 4" thick insulation, all interior joints sprayed with flexseal (20 cans), then the cherry plywood. The ceiling has fire-rated industrial lighting. Ceiling suspended and side wall mounted absorption panels. The ceiling could not accommodate the load (2X8s), so there is 4’+ thick roll insulation above the built-up ceiling. The two doors are 6’8" (800 lbs) and 8’ (1000 lbs) high and 17" thick, built identically to the interior walls.

NO bass traps needed. The room is tuned to 25 Hz low frequency flat and designed to accommodate 6 - 12" woofers without overhang. That’s why my room cost $500/sq. ft. But it is worth it!

P.S. Which record did you purchase?

The King’s New Clothes. You can paint a donkey different colors but it’s still a donkey. 

fleschler,
We had started to briefly talk about doors for sound-proofed rooms on another thread. It was identified as a difficult point. Can you detail a little bit more about your doors?  Are they off the shelf or custom manufactured?   How is the door frame built to enable the swing of the 17" depth?
