I purchased the SVS 20-39 CS+ after the amplifier on my Infinity HPS 1000 failed. Currently, I am using one channel of a Rotel 980BX to power it (120 watts at 8 ohms). In testing performance of the SVS with test tones from Avia using my Radio Shack sound level meter, I found the SVS played cleaner, lower and louder than the Infinity in previous tests in the same location. This is despite the fact the Infinity has a 1000 watt amplifier, a 15" sub and two large passive radiators. I am able to exceed 105 db at 25hz in a large room (25X15X8 with two openings) with plenty of headroom from a 160 watt amp.
