You could do it that way and it will work. However then you'd be sending a full range signal to your 450's and sub-low (75Hz and below on the CFX Subwoofer out) to your subwoofer. The more efficient way to do it would be to send the full range L & R signals (Main L&R outs on the CFX12) to your subwoofer's L&R inputs, then use the L&R High Pass outputs to run to your 450's. This way the crossover in the subwoofer will send the sub-low to your subwoofer and the rest of the signal to your 450's. This is more efficient because you don't have your 450's trying to produce frequencies already being handled by your subwoofer and they don't waste power trying to produce sub-low frequencies that the speakers can't reproduce anyway. BTW, congrats on finding an SRS-1500, they're pretty sparse and in pretty high demand since the new SWA-1501's have turned out to be such crap. |

Also, if your top box and sub are reproducing the same frequency ranges, they will fight each-other more. That's why even pros with fancy equipment spend a lot of time getting their cross-overs setup right. |
