Where are the subs?

Tim, I will have my HGS-15s repaired, but it takes planning. I’m 83, so I need help to put them in the back of the station wagon, then they need to be hauled to LA within a day or so, a two-hour drive from Santa Barbara. I have several SMS-1s, so I plan to us both the HGS-15s and 10s. Running the automated SMS-1 acoustic room correction is easy, but you can spend hours manually tweaking acoustic parameters if you wish.

I’m skeptical of your last sentence. The Ayre preamp connects to the SMS-1 which connects to the subs. I never use subs without acoustic room correction.

@dbphd, the DBA concept and what you can accomplish with your SMS-1 are pretty much one and the same. Use what you're comfortable with or try both and see what you prefer. I have used the DBA concept with 4 subs for a few years now. No room correction was ever part of the equation, didn't feel the need for it. I am trying out a line array concept now that member mijostyn recommended and find this method useful too. IIRC, he uses DSP in his setup, but again I do not. Ultimately I think the use of 4 subs will make a nice difference in your system.

BTW - was at the show in Long Beach yesterday and ran into Doug. Had a nice time. I'll be heading to LA in the next coupe months so I'll try to make a point of stopping by.

I'd enjoy a visit from you.  I have two setups: (1) Ayre 5 Twenty series digital hub, preamp, and amp with KEF Ref 1s, and (2) Senore microRendu, Ayre Codex, and Ayre A7e amp with LS50s.  Lots of Parasound stuff boxed to sell; beginning to wonder about setup 1.  I think we're a year or two down the waiting list for Casa Dorinda.  Perhaps a pair of KEF LS50s arrayed with a pair of Velodyne HGS-15 and a pair of HGS-10s would satisfy my audio needs.

Hello dbphd,     
     Millercarbon , clio09 and myself all have experience using 4-sub DBA systems in our rooms and know there's absolutely no need for mics, room correction or bass room treatments.
     However, it seems you're determined to use the SMS-1 with room correction in your new room.  I agree with clio09 that you should use what you're comfortable with but I'm not as confident as clio09 that you'll accomplish the same results from either a DBA with no room correction and a master SMS-1 for your two 15s and a slave SMS-1 for your two 10s (see the bottom of page 10 on your SMS-1 manual for setup instructions on this).
     As I stated on my last post:
     "My overall impression is that the SMS-1 and the DBA system have the same goal, to achieve accurate natural and smooth in-room bass response, but through different methods. It strikes me that the SMS-1 method is trying to simulate digitally what our brains do naturally with the DBA method.  
      The SMS-1 approach is attempting to smooth or even out bass peaks and dips in a room through room analysis using test tones and mics, digital conversion and processing along with parametric equalization. It's more proficient at reducing bass peaks than boosting bass dips since boosting all bass dips of various frequencies and decibels needs to be done more judiciously to prevent overstressing the sub or subs.
    The DBA approach is attempting to smooth out bass peaks and dips in a room through creating more peaks and dips and relying upon the proven psycho acoustic principle of our brains summing and averaging these peaks and dips which results in a perceived accurate and smooth in-room bass response. It's equally proficient at reducing bass peaks and boosting bass dips since boosting all bass dips of various frequencies and decibels requires no increased bass output from the sub or subs.
      I'm certain the 4-sub DBA system works like a charm without any mics, room analysis, room correction software or hardware, parametric equalization and room treatments."

      However,I've never used or heard a 4-sub DBA system configured through an SMS-1 and utilizing room correction so I'm not certain how well this method would work.  
     The reason I'm skeptical is because it seems to me that the two methods would be working against one another.  The DBA concept is based on producing numerous more bass peaks and dips in the room while the SMS-1 room control concept is based on reducing as many bass peaks and boosting as many bass dips in the room as possible.  
     I hope the net effect of this dueling bass response concepts results in an overall positive result but, having no experience using both at the same time, I really have no idea what the results will be.
     Hopefully, you'll have your two 15s repaired by the time the experienced clio09 arrives for a visit and you guys can figure out a good solution.  I'd love to join in and help out but I'm in Indiana and have no plans to be in L.A. anytime soon.

     Good luck and please repost here detailing how things worked out.

Thanks,
  Tim
