Hey there Dredster-
Jrinkerptdnet has described the Bam and its function perfectly. It is an entirely analog component . The only thing I would add would be that the Bam also filters out really low frequencies and subsonic garbage below the boost point. This has a couple of benefits. It minimizes distortion particularly in the midrange and saves amplifier power that would be wasted wagging the woofer cone about below the frequencies that the VSM comfortably operates over. The Bam uses the same quality of parts (the best...) as the VSM's crossover and appears completely transparent to me beyond the addition of a little more bass clout and reach. It is a very admirable addition to a pair of VSMs.
Happy Trails!
