Well, I recently integrated the mbm-12 using the minidsp.
I have always had a dip at 100hz at my LP no matter what the crossover is, or if I try speakers no subs etc. Well, that is finally fixed with using the mbm. You would think that would mean I could locate it or hear it but I can't, I just get tactile feel. I already get tactile feel from the octo subs so now it's just a matter of what mood I'm in because sometimes it's too much tactile feel in which case I just mute the mbm output on the minisdp.
The minidsp allows me to set the delay independently for the mbm, which is great because neither 0 nor 180 on the phase knob integrated the mbm-12 with the mains. 180 was better but not that great. Now I have a smooth graph and all is well.
It's so nice man, for all those years I craved a sound like this. The subs alone with no mbm give me better tactile feel than i ever had before but it's nice to know I can switch on the mbm when I'm really in the mood for it. Right now I'm about 50/50 in regards to running the mbm. Those that know me know I REALLY like tactile feel so that's saying a lot if sometimes there is too much. Never thought I'd have that!
Also, this past weekend I moved the CV 5000 amp into the laundry room which is behind the left wall when facing the screen. AHHHHH so nice not to hear the amp anymore.
Side note, I've gotten into the habit of unplugging everything when thunderstorms are in the forecast and I'll be gone all day. Best case scenario if I were hit is insurance would cover cost of my gear (not even sure if I'd get full value, I'm not sure how it works)... but I'll be damned if I'm building these 8 subs again. So, better safe than sorry. My sub amp is plugged into 1 dedicated 20 amp line and all the components are on the other one so I'll I have to do is unplug those 2 and I'm good - and I unhook the direct tv coax cable input from my box.
