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.

Hello DB,

Yes, I remember now you’ve never had 4 working subs in one room. I’d just like you to at least experience the near state of the art bass quality attainable in your room by utilizing all 4 subs in a properly positioned 4-sub DBA.
My opinion is that there’s a higher degree of elegance in a single system that’s capable of high quality performance for both stereo music and HT, especially if it incorporates a 4-sub DBA producing very high quality bass for both, because it requires more thoughtful design and will offer superior bass and overall performance on both.
I think it’d be a shame not to even try out the 4-sub DBA concept on either music or HT in your room because you have all the necessary component parts, once both subs are repaired, and I sincerely believe you’ll be amazed by the bass seamless integration with your main speakers as well as the extremely high bass quality. You'll probably have both subs repaired in any case, right?

Tim,

I think we are expected for Thanksgiving at out cousins in the Hollywood Hills.  We may make a two day trip of it and drop off the subs in LA the day before.  When we have four working subs, I'll try them with the stereo setup.
Hello DB,

     Happy Thanksgiving!  

     I'm disappointed, you're not even going to give the 4-sub DBA concept a try?  Please trust me, you'll be amazed if you give it a try on music or HT.  I certainly was.  C'mon, be adventurous.

Hello kgveteran,

     I don't know what millercarbon has against "horrid sounding HT" but, I know that with 1 to 4 subs optimally positioned in a room, HT does not sound horrid at all and works equally well for HT and music.  I know this because I've been doing and listening to both HT and 2-ch music with a 4-sub DBA for over 5 years now.  
     I also wanted to let dbphd know that I recently bought an Oppo 205 for a reasonable to me premium of $2,100 and won't be needing his.  
     I haven't been following this thread as closely as I was earlier and was wondering how dbphd was doing with his system.  Hopefully, he'll post again soon to let us know.
     On a side note, I've been busy lately upgrading my own system from 1080p to 4K.  I bought an Oppo 205 to replace my 105 and ordered a 4K LG C9 77" OLED hdtv to replace my Panasonic 1080p 65" plasma.  I'm also having a local hi-end retailer treat my room fully as soon as I receive my order of required room treatments from GIK. This should be interesting and educational.
     I'm also looking forward to watching that Over Lord disc you posted about.

Thanks,
 Tim
