    I have an Onkyo TX-SR501 receiver, Velodyne CHT-12 sub, and Polk RTi6 fronts

    I always go stereo for music, so thats all ya need to know by way of equipment.

    I tried running a 40 hz test tone from my computer (which is basically my media machine) to my receiver via a mini-to-rca cable. The crossover is set to 80hz on the receiver, and direct on the sub, so as I understand it, all of the low frequency crossover is handled by the receiver, and anything 80hz and below directly to the sub. When I ran the test tone, I was able to hear something very faint coming from my speakers. Is this normal, or should I do some more inspector gadget about whats going on?

    Well unless it is digital, there would be no way not to do it that way.

    Most xovers are analog, and that is really just how it works being analog.

    You want slopes for "smooth" transitions between speakers so individual drivers can handle specific audio regions they are best equipped to handle, just like you would want with individual drivers in a speaker cabinet. With most receivers its 24 db/octave low-pass and 12 db/octave high pass.
