Apple Logic Pro /LogicExpress Discussion

Hey Guys,

     I attended a "Home Studio" seminar put on by Berklee College of music faculty a few 
years ago.   One thing they recommended for an economical subwoofer is to use a good 
home-theater model.   I have a sub now, but my i/o amp isn't enough umph to drive the 
thing.

     Any technical and economical advice from the Logic gallery here?

      I can't find any photos on the internet but It does say:   Nominal impedance, 8 ohm

     Thanks!

       Pete
