I also have a sub-woofer (JM Labs SW900) and mains (Acoustic Zen Adagios), but my sub does not have crossover outputs to the main amp. My pre has 2 sets of main outs, I use one to the sub and one to the main amp. Therefore, the full frequency range goes to the main amp/speakers. What is the best way to roll-off the lows to the mains in this situation ?
Sub Question
I tried to do a search, but could not drill down on this. Anyway, I have never owned a sub. I never really felt the need. However, I had a friend tell me that a sub does more than just enhance bass output and perhaps bass quality. He went on to say that having a sub takes pressure off the driver thus making the speaker do less work. Because of this, the speakers will sound better or have better clarity. Thoughts?
