Hi, I'm a bit confused in setting up speaker config on my avr-250. I feel like there should be at least two cross over frequency parameter. One for setting the the 'small' speaker crossover point and one for using the setting Stereo Mode : LARGE+SUB. My large front speaker can go down to 35 while my center and rear can only reach 70 Hz. Utltimately I think there should be 4 crossover; 1 for front 1 for rear 1 for center and 1 for surround back. That way, it would be clear what frequency is going where. I dont think it would need much power from DSP, I would accept to trade the bass/treble adjustement for the crossover setting.
