I have infinity IL60s (with internal 500 watt powered 12” sub-woofer -3db @ 28Hz) as my front speakers. I currently do not have a separate sub-woofer. My receiver is a Yamaha 795a. Infinity’s recommended setup: 1. Set the IL60s as small 2. Route the receiver’s LFE channel to the line input for the IL60s’ subs. 3. Set the IL60s’ subs inputs to line vs. speaker. 4. Turn off the high pass filter. The IL60s crossover to the sub is at 150Hz. The Yamaha’s crossover is at 80Hz. What is handling the range in between 80Hz and 150Hz? I understand that crossovers are gradual, but the LFE is going to output 80Hz and lower right? The Mid bass speaker in the IL60 will start fading out below 150hz, but nothing will take over until 80Hz. I am sure I am missing something. Can anyone explain this to me? Right now I have the IL60s as large, and route the receiver’s left and right pre-amp out to the appropriate IL60 sub’s line in. This way I will get bass from my DVD-A. Since I don’t have a separate sub it seems like the way to go. I will eventually add a dedicated sub for movies. I still want to leave my current setup as is so I don’t loose bass on DVD-As. By the way, The IL36 center channel is in the mail, and I intend to purchase Infinity IL40s for the surrounds. I am considering a Paradigm reference servo-15, but that may be in the distant future. Any comments on the IL40s and the reference servo-15 would be appreciated as well.
