Operating rather like a subwoofer in reverse, this crafty device controls low frequencies but takes up far less space than conventional bass traps.
Without doubt the most difficult acoustic problem to resolve for the vast majority of project studios is the challenge of low-frequency standing waves or ‘room modes’. These create a rather ‘lumpy’ low-frequency response in most rooms, where some bass notes boom and ring on for a considerable time, while other notes are very weak. These fundamental problems affect recording spaces as well as listening environments. Every room is different, as the affected frequencies relate to the room’s width, length and height dimensions, and the ratios between them.
