When blending speakers in a room i find the range on the speakers doesnt really matter as long as ur not trying to play at or below there minimum. All the x-over settings and moving speakers around are just to get them to blend together well and are mostly dependant on ur room. Ive spent many hrs with REW and mics and moving speakers (huge pain in the azz) to get my system to sound the best it can and was trying to run all my towers lower or full range but just couldnt get it better than with them crossed at 60 (really 60-80 either would have worked but i fought for the lowest setting lol). Then on top of that the settings will vary based on how ur using the system. Theater surround or atmos or 2channel stereo or multi channel stereo ect. Its never ending lol
