I can appreciate all my speakers sounding a little different... when I do a speaker test on my yamaha rx-v530, each speaker sounds a little different. One may sound slightly higher pitched than the other, etc. As far as I know, that's normal. However my center channel sounds way different than I think is normal. Even my right and left mains are different. It's a klipsch RC-35 and my other speakers are the RS/F/C 35 klipsch too (keep opinions on why klipsch is good/sucks out of this thread, please). They're all hooked up on the same type of cabling. The problem is my center channel has no power behind it and is weak. I was playing a game earlier, and there was a pipe emitting steam. If I did a full 360 next to said pipe, all speakers would sound relatively normal except when it was directly in front of me, the center channel would make the steam much higher pitched and it would not sound well. If I had to describe the problem, if my mains were a giant sumo wrestler hitting a gong, my center is a skinny little man shaking a tambourine. Any idea on what I can do to make my speakers all sound the same or is this as expected? Thanks..
