The room is 19'x21'x8' ft with floor to ceiling basstraps in the corners. The entire front wall is covered in Roxul R12 acoustical panels hidden behind heavy Velvet curtain. A quarter of each sidewall is also covered with Roxul 12 panels. Overall the room is well damped but not overly so.



We spent the first couple of hours setting up the subs on the left side midwall 3 metres from the seats, and connecting them to a switchbox for blind testing. Each sub was equalized flat using an SMS-1 bass management equalizer for easy switching as well. The display and mapping function with this unit make for relatively fast calibration. All subs were calibrated level at 80db, 2db hot or 3db below Dolby reference and checked for phase. The idea was to test these subs using a variety of demanding music and soundtracks, and in particular to see how they behaved when pushed near their limits.
