External Crossover


On the advice of SVS I changed my setting on my subwoofers from 50 hertz to 63 hertz. In addition, I turned the volume up. The change opened up the soundstage, more detail, better /more defined bass. Not a night and day difference, but easily heard. Now I'm looking into purchasing a JL Audio CD-1.
Two questions:
1. Are there other external crossover units that I should consider?
2. Should I expect similar results as when I changed the low pass filter from 50 hertz to 63 hertz with the external crossover?

Bob_reynolds,

I have a Jeff Rowland Continuum S2 and it has 1 pair of balanced and unbalanced outputs. It has 2 pair of balanced and unbalanced inputs, as well as a bypass input. I told HSU what I had, he said he looked it up and adding an external crossover wouldn't benefit me. Maybe someone with more technical knowledge could explain why an external crossover wouldn't work with my integrated amp. My subwoofers are SVS SB13 Ultras.

Bob_reynolds,

First and foremost let me say thanks for taking your time to answer my post. My thoughts were an external crossover would provide more adjust-ability; thus making it easier to blend the subwoofer with the main speakers. So yes, my plan was to filter the lows totally out of the mains to prevent overlap...at least that's what I thought an external crossover would enable me to do. I knew my subwoofer has a low and high pass filter, but I thought an external crossover would provide more flexibility. Now I understand that I don't have the option of using an external crossover...thanks again!
