"The Model Seven's bass EQ was a godsend. While higher frequenices were addressable with RPG Diffusor products at the first- and second-reflection points on the sidewalls and ceiling, without the low-frequency tuning adjustments of the Sevens' subwoofers the low-frequency readings at my listening position still looked like the Rocky Mountains - and the booms and suckouts those readings predicted were what I heard. After adjustment, except for one narrowband room mode, the bass fell within a flat (+2dB/3-dB) response all the way down to 20Hz."
"The M7-HPA amplifiers have joined my Vandersteen Model Sevens, now upgraded to Mk.II status, to form the backbone of my reference system. The quality of sound I’m hearing from them is beyond what I could have hoped for, let alone expected, even a year or two ago."
