LSi25 setup question

pmckeealaska

I recently moved and forgot how I had my system hooked up and wondering if I ever had it setup for best perfromance. I have a full LSi 5.1 setup with LSi25's as my two mains and have a NAD T763 reciever and Rotel 1080 2 channel amp. My question is mainly about the 25's. The T763 has 2 subwoofer outs and I have the subwoofer cables running from the reciever to the "line level in" on both speaker subwoofers. I have kept the binding posts on and the reciever is set to a crossover frequency of 80Hz. Is this an optimum setup for these speakers? Should I be running the subwoofer cables to the "lfe in" on the speakers subwoofers? If so, should I remove the binding posts? Finally, should I have the 25's set to "small" or "large"? Many thanks for any help you can provide. I've had these speakers for 6 years...maybe I should have asked these questions sooner....I wonder if I've been missing out on even better speaker performance??

Run them small, LFE, binding posts off

Don't run them small. That setting is almost always 120hz or higher. Manually set them to cross over at 80hz.

Thanks Ben. Thats what I thought. When you say manually set them, you mean the subwoofers, right? I have the reciever crossover freq. set to 80Hz already. Should I be using my subwoofer cables at all? To my ear it sounds better with the cables but I'm not sure if I'm in danger of "double filtering" with it this way??

On your 25's I think it has an XO knob. Just turn that up all the way(250hz or whatever) and let the receiver do the XO point for you. Yes use your sub out from the receiver. You may need a "Y" adapter to hook both of them up.
Take care and enjoy.
