- Receiver - Pioneer Elite SC37
Well, my system was fine for about 2 1/2 weeks. I don't use it every day so there could be a period of time where I go without listening to it for 3-4 days in a row. Few days ago, after not listening to it for several days, I fired up to watch a movie. I noticed that the sound was kind of "muddied". It wasn't as clear as it was before. I had not touched anything on the receiver. All the settings, wires, etc were the same as before, however the sound was not as clear. I reran the MCACC on my receiver hoping that it would solve the problem but it hasn't. The problem seems to be the center speaker (6C) where the sound is not as clear as it used to be.
The dialogue of movies sound muddied. The sound is not very crisp. It's hard for me to explain the sound. The "S" in the movie dialogue doesn't sound clear as my cheap Sony HT speakers that this unit replaced. Kinda sounds like something is holding the center speaker back. I am not sure what could be causing this? Could it be a bad speaker? How can I trouble shoot and find out what the issue is. Has anyone else ever experienced this issue?
Any info is greatly appreciated.
Sorry to hear about the trouble with the 6C. Dynaudio's suggestion is a good one, another thing you can do is to press gently on the center of the 6C's and 6B's woofers so you can listen to the tweeters by themselves.
If it sounds like you are getting reduced output from the tweeter in comparison with what you are getting from the 6Bs, then please give us a call and we can swap out the 6C for you.

If I need the secondary amp, I have no clue what to get beyond the prescribed "emotiva" brand. Do the watts "add,: so this UPA-2 that does 125 watts @ 8ohms will give me 225 watts with a 100watt receiver? Does it even matter that I am asking this question, will adding in the UPA-2 do the trick (or the Onkyo 282, as it is only 200 on amazon)?
A little more info: I am thinking of getting the 6B's for front L/R, the 4C for center, the 4B's for back L/R, and the 8A sub since there is a cheap, refurbished model on the website. I want the 6Bs because I think it would play Led Zeppelin better than anything except the 6T's, which I don't have the money for. And while music will be my main priority, I will also use the system for gaming and the occasional movie, which is why I don't want a simple stereo setup. I started off considering the mordaunt short alumni 2 system, but the speakers seemed so tiny; I didn't think I would be able to fill my room (~ 22x15 with high ceilings around 11 feet high).
I'm really worried about the power requirements for the 6Bs, as I don't want to spend an extra 400-500 dollars simply to power speakers that are slightly beefier than the 5Bs. Unfortunately, that may be necessary, which is making me wonder if I should consider other options. Hopefully I figure this out soon, because I don't want to miss out on A) the Aug 31 sale deadline, and B) I need to have my system in place for Halo Reach on the 14th (yes, really).
I don't think that a 100 watt/channel receiver will be enough to really drive the 6Bs well in a space of that size.
But no if you use a power amp you are no longer powering the speakers with the pre-amp. However 125 wpc from a power amp should be a sizable step up from an AVR w/ 100 wpc in terms of current and the UPA-2 should drive the 6Bs fairly well.
So if you do go with the 6Bs I'd either get the UPA-2 or a beefier AVR like an 800 series Onkyo or a 3300 series Denon.
I would also add that when properly powered there is a pretty sizable bump in terms of midrange and bass from the 6Bs over the 5Bs.
However if you don't want to add an amp or get a more powerful AVR you might consider a third option, the more sensitive 4T which should do pretty well in that space with a 100 wpc AVR.
Hope that helps!
