  any use of a sub EQ (such as the ones in the jl and new Paradigm subs or a standalone one such as the SVS) will add significantly to the effective distance because of the latency of the DSP.

  • Interesting dilemma... I have a couple of daisy chained JL audio subs - oscar 16:01:45 12/18/09 (1)

    both at different distances in different parts of the room. There is an alleged one time "auto-calibration" ritual using a microphone to help the subs figure out automatically what each is supposed to do as the subs self-generate test tones. How does a preamp/processor know how to handle this ?
    
    Problem should get even more intesting when(/if?) the recommended four (4) subs are implemented.

      This is a complicated issue. There are a few interesting approaches.
      
      One is the SVS-EQ1/Audyssey SubEQ approach in which the subEQ takes care of the differential in delays of a pair and the bass management in the processor deals with the net performance of the pair.
      
      There is another from JBL which handles up to 4 subs and EQs them.

  Especially important. You notice the delay (=distance) much more easily with LF signals.
  
  I forgot about this issue with the Oppo (say) BM...and it isn't going to be changed soon either since it originates with a (non-custom) chip maker. I don't use the mch analog outputs anyway.
