Hi Bob,

I am looking into a crossover for my subs as well
I might be missing the idea of what you are trying to accomplish but, you seem to be confused about crossovers. You do not need a crossover for your subs. The crossover I believe you think you might need is already built into your receiver. The next paragraph is copied from page 19 of the Anthem 1120 users manual.
3.2 BASS MANAGEMENT
In this menu, information about your speakers is used so that bass does not become distorted. If using Anthem Room Correction, these items will be set during measurement, so you may skip this menu.
If your subwoofer has a crossover, it should be bypassed – set its frequency control to the highest frequency.
The bass manager is a crossover that divides audio in two frequency bands suitable for subwoofer/satellite speaker systems. The result is a lower bass level for satellite speakers, and no midrange/treble going to the subwoofer.
I hope this helps.
