    Im running a harman kardon avr325, 2 technique speackers(front)polk rm 6700 speakers with a mtx 12 inch sub. Do I just hook up all my surrounds straight to my receiver and just run the powered sub from the receiver. Also what crossover settings etc. do I set. Should be getting my avr325 from the repair shop next week, just preparing.

    A general compromise crossover setting would be 80 Hz. Assuming, of course, your receiver allows for it.

    Is it alright to leave the main power on the receiver on at all times or should I turn it off(Button that you push down and stays down)

    I'd switch it off, to "standby" mode. Some people leave the things turned on 24/7, but I emphatically would not do this.

    That "main" switch should stay in. The other "lit" button is the one to use daily.

    I don't think you have them high enough. The appear to have 3.5 inch drivers, and my guess is that they have little output below 120Hz.

    If you have a test disc with tones in that area, try it the way you have it but unplug or shut down the sub. See where the mains drop off and adjust accordingly. Since thay all will perform the same, the main's response will be the same for all, adjust the same for each channel.

    If 120 is an option, try that, and keep the sub as close to the mains as you can.

    Some companies suggest that their mini speakers be run full range, and to blend the sub by ear. Energy does that.

    It's up to you and your ears, though. But generally, keep the bass away from the mains. If they cut off acoustically (-6db) at 90, x over at least at 100, prolly 120....

    Tools that are useful = RS SPL meter, test disc burned with custom tones, and prozac because this will all drive you nuts. Set it up and forget about it.
