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.

Okay listen first off its not gonna sound like it but I totally get it. People with HT setups love their HT setups in spite of the horrid sound. Or maybe even because of the horrid sound. I get that. Do not understand why anyone would want to waste their money on horrid sound but they do and so I totally get that.

I was watching Over Lord last night, if anyone wants a demo scene on their Horrid sounding HT :0) , this is the ticket,the first 15min is a roller coaster.
 
And that was the 5.1 version on PrimeVideo upmix to DolbyD+DDS, I immediately ordered the 4K Atmos disc

Hello kgveteran,

     Just wondering why you quoted the above comments from an earlier post by millercarbon?
     I believe millercarbon intended these comments satirically and was referring to lower quality and more generic sub installations, not dbphd’s higher quality installation. I believe this because I know that millercarbon is very well versed on the theory and excellent bass performance levels obtainable through a properly positioned and configured 4-sub distributed bass array (DBA) system, having recently built four subs and deploying them in a custom DBA system in his system and room.
     He has first hand and extensive experience, as I do, listening to a 4-sub DBA systems in our own rooms. We’re both very familiar with the near state of the art bass response performance these systems produce for both music and HT.
     Exactly which "horrid sounding HT system" are you referring to and why'd you feel the need to repost millercarbon's comments?

Thanks,
Tim

     Just as I suspected, you had no legitimate purpose or reason for including and misconstruing millercarbon's prior post.  Thanks for confirming this.

OmniMic or REW are more accurate Measuring devices. Promoting anything other than measuring with instruments is misguided advice. 
While multiple subwoofers are accurate advice, and provides enduser with a smoother response at the LP, this is 2019 and we have software and hardware that are affordable and accurate.

a comprehensive multiple subwoofer array setup scheme combined with proper calibration equipment will get you much closer than archaic “crawl” method.

If crawling around was a conclusive method, Kef and Velodyne would scrap their testing facility and hire professional “Crawlers” :0)
