A video of the Big System in action at low power levels, at the Bass Pig's Lair. View of BassMaxx new ZR18 subwoofers on the end stacks, driven by QSC 6,000-watt power amplifiers, plus Electro-Voice EVX180B mid-bass drivers near the center. A separate set of microphones was used to capture the audio, because the camcorder cannot handle the SPL or the frequency range. The song is a Korean title from the TV series "Save Your Last Dance For Me" chosen because the bass player is playing an extended range bass and it gets down nice and low.
