Great advice by the last couple posters. Unless you have the outlaw amp it takes way more power and strain on an average avr to push mains down to 40Hz or less if their capable. Let capable subs handle that load. Crossing over your speakers at 80Hz doesn't mean their not producing below that, they will roll off depending on slope down to 50/60Hz. Now this is beyond my expertise to explain in technical detail but it just means less strain on your avr and more work load to subs built for that load.
If you really want all the info you can use,,, check our Mikes thread (guid to subwoofer calibration and bass preference) in the subwoofer home page. He spent a lot of time and work sharing his knowledge which would be beneficial to most.
