    Hello, I have some questions: I have recently connected my small front speakers (klipsch quintet 2)  on to my subwoofer. And my subwoofer to the frontspeakers connections of my receiver (sony str-870 db).Then i set the fronts to large and the subwoofer to no. I have understood that this is the best solution  if you have small speakers and a subwoofer. My first question is: what is the best crossover setting now for my subwoofer? second question: I have set the center and the surrounds on small and the herz of it on my receiver on 150 hz. third question: And the L.F.E high cut on my receiver is set to 120hz. Is this all okee? thanks

    I'm a little confused about your sub/front speaker configuration. I assume you are using the high-level inputs on your sub. But why don't you use the line level output on your reciever for your sub instead? This way you will get a sub level control, that is adjustable to your music/movie selection.

    It sounds like you can set your set your front's to small, and turn your sub on. Run the sub on it's line level input. Then the LFE cut off should be set where your speakers frequency response rolls off. Then dial your sub XO to match that setting.

    Where your speakers frequency rolls off, is basicaly up to you. I find that speakers frequecny response is usually over rated. So, I would play your system with your most bass heavy material, without the sub. Now you can decide where the bass in lacking. Starting from the lowest sub XO setting. Slowly dial it up until you fill the areas of bass that are lacking. Then take that number on the dial and set your LFE to that region. Be sure to play around, because crossover slopes, can sometimes conflict with each other. This can leave gaps in the frequency spectrum.

    In your present configuration, the front speakers are getting the full range LARGE setting output.  The subwoofer speaker input and output terminals are are tied directly together.  The input to the subwoofer circuitry is tapped off the speaker inputs.  The subwoofer crossover adjustment only effects the subwoofer output.
