Hi Can anyone tell me why the popular BFD is the best product to use to tame your bass frequencies? Is it because you can specify all of its bands of PEQ to be in the sub-bass range rather than just buying a different PEQ designed for full-range sound and only the 1 or 2 of its bands dedicated to bass? Will a BFD be loads more useful that a single-band PEQ as included, for example, on SVS ultras? any help would be appreciated. ALSO... the BFD's bandwidth is specified as 20hz-20khz. Does this it mean it will cut the signal off below 20hz, or just that it can have no effect on these frequencies? cheers!
