Powered sub hook up question

207.62.70.250

This question may have come up from time to time before, but I have not been able to find it in the archive.

The pre-pro I have has only one sub-pre out. How do I hook it up to two powered sub woofers? I used a Y connector but found the bass not very strong. Thank you for your help. Peter

Y connector. Not strong enough? How have you calibrated the levels? What crossover are you using?

  Hi Kal,
  
  Thanks for your response. I have not calibrated the level yet and the crossover at 60 hz. .
  
  I have Definitive Tech 7004 as the front speakers. I just realized I set these speakers to �large� and all other surrounds to �small� with sub-woofer set to �present. Is this setting Okay or should I set the front ones to �small�. I am not by the speakers now so I have to do that tonight. Thanks Peter

    A. This assumes you have a real separate sub, apart from the ones in your 7004s:
    1. Yes, leave the fronts set to LARGE in order to take advantage of the powered woofer in the 7004s.
    2. How have you set the crossover to 60Hz? This must be done in the receiver with the subs' own crossovers either bypassed or turned as high as possible.
    B. This assumes that the 2 subs you refer to are the ones in the 7004s:
    1. Yes, leave the fronts set to LARGE in order to take advantage of the powered woofer in the 7004s.
    2. Set the crossover for the rear SMALL speakers to 60Hz in the receiver.
    3. Set the LFE/subwoofer in the receiver menu to NONE.
    4. Use the regular speaker wires to the 7004s; have the 7004s "subs" connected internally to the regular inputs; use no separate SUB/LFE interconnects to the "subs."
    A pox on speakers with so-called built-in subs!!

      Scenario B is correct. Thanks for all your help.
