i used to use stereo subs w/ my milleniums: entec LF-20s, placed slightly in front of the VSMs to time align them. bamm was taken out, and i put a passive x-over (much like those found on audioc.com) in line w/ the amp to roll the VSMs off at 100hz, with the subs running full range. i had to decouple the subs from the floor to reduce a bloatiness in the bass.
with all that, i had it REALLY close. indistinguishable almost from the merlins w/ the BAMM in place. result was a lot more impact down low and a much bigger stage per the 20hz area info.
ultimately i sold them, when push came to shove. i got tired of having all the boxes, and when given the opportunity to buy a world class digital setup for the $$ i got for the entecs.
i think there's probably a few good subs out there that would work --- none of them fire downward BTW. i cannot stress the importance of that point enough.
