My setup isn't high end as im a student, but all the same it's not bad. I used to have 5 speakers (all eltax) all were 80watts speakers. My reciever outputts 5x 80watts (and another 80 for the sub). However i recently upgraded my 2 front speakers to some eltax floorstanders, These are rated 180watts. (all speakers still have 88spd btw) -this isnt a problem listening to msuic in stero as i just have to turn the speakers up. -However in dolby pro logic for movies, the 2 front speakers are noticably quieter than the center (as it need less wattage to be full driven i presume?) Any solutions?
