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 millercarbon,

     Okay, thanks for elaborating and clearing things up.  I didn't realize you were referring to music being played back via a 2-ch system compared to a multi-ch system. I was perceiving your comments more in the context of how I utilize my own combination system, using 2-ch exclusively for music playback and using multi-ch exclusively for HT playback.
      I completely agree with you that, when comparing music played back on 2-ch vs multi-ch systems, by far the most important factor when it comes to being believable is quality and it matters far more than the number of channels. More channels in this case is not necessarily better.
      I know many have built and enjoy high quality multi-ch music playback systems. While I readily admit that I currently have no experience or desire in doing so, I still suspect I'd be highly impressed by the sound quality of many multi-ch music systems others have built.
      Reconsidering your comments in this context, however, I believe you're actually commenting more on the importance of quality in general rather than the superiority of 2-ch or multi-ch as a quality playback method more specifically.  
     I definitely agree with you on the importance of quality but also know it's possible to combine both in one system with shared components and speakers; a high quality 2-ch system for music playback and a high quality multi-ch system (up to a 9.1 with Atmos) for HT playback. I think we're both in agreement on this.

    Oh Tim......you didnt......a surgeon......ur gross......i find this pathetic......i have to bow out of this exchange.
Hello kgveteran,

     ?...Wtf... ?  You've chosen to be a cowardly baby chicken?

I thought I had posted to this thread but I can’t find it.
So here goes my take on the subject.
With my 2 channel I use 4 JL Audio F-113 subs. With my home theater equipment it adds 4 more subs of various quality.

Yes, I believe with 2 channel audio the quality of the sub (s) matter. But with home theater you just need subs that can do deep for crashes, explosives and such.

Hello Ozzy,

     I didn't realize you're a 4-sub distributed bass array concept adherent on your 2-ch music system.  It seems like you  decided to try the 4-sub DBA concept out with a vengeance; employing four $4,000 JL F-113 very high quality subs in one's 2-ch music system not only represents the most impressive example of any custom 4-sub DBA system I'm currently aware of, it's also extremely cool. 
     Congrats!  I'm very interested in how you learned of the 4-sub DBA concept,  what convinced you to give it a try, why you decided to use such high quality/expensive subs, how much of a discount you got buying the 4 JLs and your overall DBA performance impressions in your room.  
     Oh yeah, I disagree with your comment about the quality of subs being more important on music than HT.  I believe using higher quality subs on both are easily discernable and improve performance.  I think you and most would likely agree with me if they swapped out lesser subs for JL F-113s in their music or HT systems.

Thanks,
 Tim
