just to clarify some points, also posted on aa.
the x max of the woofer is 24 mm which equals some 15 to 18 inch jbl drivers. with the fs of the driver being 28 hz, it likes to go low and move a lot of air. the filter at 28 hz in the super bam, removes out of band output which reduces im distortion elsewhere. with the use of the bam we were able to optimize the bottom end of the speaker in amplitide and phase while utilizing a smaller encloser to keep sensitivity higher, reduce distortion and greatly improve the midrange clearity and uniformity. this enables the vsm/bam to be used with lower powered finnessed amps. in essence, what is missing is 16 to 30 hz. this is the lowest octave so you would be wanting for the lowest pipe organ notes and some electronic music only. all other acoustic instruments, jazz, blues and rock are handled by the in band response of the speaker. the speaker is just not designed to fill large spaces or go super low which can be a benefit in a large environment. the vsm is designed to work in normal sized living environments. if you need more bass quantity in your set-up consider changing something in your system to improve the tonality. give me a call for a discussion.
thanks,
