By "full" I assume you are saying your receiver set your m80's and 180 to "large". Audyssey does not do this, but looks for the -3dB point of each speaker and reports this back to the receiver. Each manufacturer of the receiver would determine if the speaker is set to large or small. Most of them use 40hz as the cutoff, which Audyssey recommends.
Anyway, unless you don't have a sub, you want to go into the receiver setup and change each speaker that was set to "large" to "small". The crossover for the m80's and 180 could then be set to 60-80hz.
after doing the calibration on my Onkyo 5507 pre-pro it set my front 3 (a pair of M80's & a VP180 all V3) to 40hz and i love the sound they all put out. all voices sound perfect and all spoken words make perfect sense to me. if that's where your speakers were set after your calibration program and if you like the way it sounds leave it. i did and i don't intend to move mine. mind you it's not going to be for or be accepted by everyone. good luck! and keep us posted on whatever you have chosen to do and why.
