Separate subs for music and HT/surround

My stereo setup is comprised of Ayre 5/20 series digital hub, preamp and amp that drive KEF Ref 1s through a passive Marchand high-pass filter. For HT and surround, LR side and rear surround from an SP3 go to NAD Class D amps that drive LS50s. The SP3 receives HDMI from an Ayre DX-5 DSD, and its front LR output goes to a balanced by-pass input of the KX-5/20. I have two Velodyne SMS-1 bass managers that provide acoustic room correction, two HGS-10 subs, and two HGS-15 subs.

Question: Should I use one SMS-1 with the two HGS-10s for stereo and the other SMS-1 with the two HGS-15s for HT and surround music? I realize there are advocates for using 4 subs, and I could daisy-chain the SMS-1s, but separating the SMS-1s seems a neat way to keep stereo separate from HT.

I just recently realized for music (in stereo) i have to dial back my subs to -12db, for movies i go back to -4.5b where Audyssey put it. I leave Audyssey engaged and DynamicEq on also, for my low level music its works
the two surround modes (Denon X4300), dts and Dolby both stink for surround music, I miss Prologic II.......
my subs are on either side walls 1/3rd into the room from the front screen wall, my LP is 1/4 into the room from the back wall, no EQ needed, it was all about the level. 
I have a rolling 600lb door that seals off the room for late nite watching, but I prefer the door open for music.........

It sounds like you're Music Reproduction System is improperly aligned, tuned, or installed for this to be the universal result with you're setup.

The Velodyne HGS-15s are now behind the KEF Ref 1s, an HGS-10 aside each Ref 1.  The HGS-10s are connected to one of the SMS-1s, the HGS-15s to the other.  With the SMS-1s daisy-chained I can turn one off if I want only the HGS 10s or HGS-15s.  I've been listening with just the HGS-10s active and I like it for music.  Makes me wonder about replacing the HGS-15s with another pair of HGS-10s.

The Sanus rack makes equipment very accessible and is a joy to use.  Should have done that years ago.
