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 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
nobel100,

2 of the F-113's are used as Masters and 2 as slaves. 2 are V2 and 2 are V1. I purchased them individually until I accumulated the 4.

With Hometheater I am still using the JL Audio subs (via HT pass through on my Ayre Preamp). The Denon receiver adds another 4 other subs, M& K Sunfire, Outlaw Audio for a total of 8 subs.

Hey Ozzy,

      You know what they say: 2 subs perform twice as well as 1, 4 subs perform twice as well as 2 and 8 subs are good grounds for a divorce. 
     I'm just using the four Audio  Kinesis Debra subs, 1'x1'x2' with 10" drivers, and I'm getting near sota bass performance in my room for both music and HT.  The only way I can even imagine the bass being improved is by using four JL F-113s


Enjoy,
 Tim
Tim won't like this, but my current plan is a stereo setup comprised of Ayre Series 5X Twenty components and KEF Ref 1s, and a surround/HT setup comprised of an Oppo 205, NAD M22, and a pair if NAD 268s with six LS50s.  Current thinking is to use the Velodyne HGS-15s for stereo, the HGS-10s for surround, but that could be reversed.  An Audible Illusions Modulus 3 might be used with the Thorens TD 124 in the stereo setup, making Roon, discs, and vinyl sources for stereo.  HDMI from the disc players would be for video only.
