REL No.31 powered subwoofer
With subwoofers, he's at his worst. Did you hear that?, he'll exclaim when he worries that a low bass note received too much emphasis. He nags and niggles that perhaps the integration between the main speakers and the subwoofer leaves a crater somewhere in the low-frequency band. He harps, not always believably, that he can hear where the subwoofer is, even though deep bass is supposed to be impossible to localize. Most of all, he barely lasts a song without getting twitchy about the sub's gain setting, imagining that he has to dial in exactly the right amount of deep-bass presence with each track.
