With MC and
others, I have to recommend going with as many small decent subs as you can
instead of one expensive sub. Minimum: try for two good 10” or 12” models. The
distributed bass array concept works, and very well; it’s science. I just moved
out a great REL B1 and moved in three SVS units (two SB-2000s, one SB-3000) and
the bass and openness is better; I’m not going back. I’d like a fourth.
And, there are a
lot of very good high-performance inexpensive subwoofers out in the market
today like Rhythmik, HSU, SVS, plus the higher priced RELs J&Ls, etc. I’d
consider 2-4 of good $600-?00 subs, seriously.
Unless you have
amplifier concerns I’d not worry about high-passing unless your mains need that
high pass. For higher volume playback it might be beneficial to keep energy
away from main woofers possibly. My mains run unimpeded and all subs are low
passed at 50Hz (with low volume). The increased ‘air’ is wonderful.
Sorry if that
wasn’t what you wanted. After fiddling for 40 years with sub ‘specs’ and
technical BS I now realize the DBA concept totally runs that old thinking out
of town (at least in my own practical experience, and like that of many others).
