Crossover for Energy RC-70,RC-LCR,RC-10, Subwoofer

I just installed Denon AVR-X4300H and mic calibration showed crossover frequency for all speakers with 40hz and large. I changed front, center, surround,to small. I have a question on crossover - should I leave it or what would be the correct crossover frequency? By the way, I have BIC Venturi 1200 subwoofer. Thanks.

I would set it higher than 40 hz because the sub will be much more efficient than your Energy speakers at reproducing frequencies well up to 100 hz. But as you get closer to 100 hz you risk causing a bass bump between your main speakers and sub; increasing the chances of unwanted and unnatural sounding standing bass waves, localization of the subwoofer as a point source, and excessive bass boom.

Some playing around is likely in order to see how your system in your room performs best but I would say set the crossover on the subs amp at highest point and set the receiver to send 80hz or lower to the LFE channel as a starting point.

It appears that 80 hz crossover is commonly used. Some people also use 60 hz. I use 80 hz and I am with it. By the way I also have same energy speakers as you! I love them.
