The idea was to build a small HT/Media room for 2-6 (limited space) people in the basement. Since it was built in a townhouse (condo) which is ~20 years old we wanted to add soundproofing as well.

For the soundproofing I used ASC ISO Wall.

For the acoustical treatment I used ASC studio sets (the best most price/performance value).

I used CobaltCable for all of the wiring.
