i had posted this in the speakers section, but no reply . have a fixed crossover htib receiver, about 2 yrs old 6.1 . there is no menu setting for speakers large/small either. so assume if selecting yes for subwoofer, all the speakers automatically are assumed small by the receiver ? as there is no setting for crossover thats selectable on receiver i should then just crank up the subwoofer crossover to it max or at least 20hz more than the receivers fixd crossover ( which i beleive is 90hz) or do i set the sub somewere around what my old front l/r polk monitor 10's lowest cut off point is ? specs for these fronts are : Overall Frequency Response 25Hz - 25kHz Lower -3dB Limit 37Hz Upper -3dB Limit 25kHz Nominal Impedance 8 ohms Recommended Amplifier Power 20-250 w/channel Efficiency 89 dB from above what would be the lowest point the polks go down to ?? a simple yes or no would be great, as i hate sitting here thinking it could possibly be wrong ! thanks

The best solution should be to set the crossover on the sub to its highest point, or to bypass. Use the LFE input if it has one. The receiver is doing the crossover and it appears you can't change its settings, so the crossover in the sub will just interfere with it, thus you want to bypass the sub's crossover. The capabilities of the speakers is not a factor, since the receiver crossover can't be changed. If you get a new receiver with variable crossover, it will be a different issue.
