Does that mean that it would be ok to place this center channel within a couple inches from the wall, say 3 or 4 inches, instead of 12 like I have it set up now? I don't think I'm using the lows too much on this speaker but I could be wrong. I have my AVR set to do crossover so that everything from 80hz and below goes to the subwoofer. As for the rear ports being too close to the wall, I thought they needed at least some clearance so that the air could come out of the ports unrestricted without being blocked by anything. Is this true, or not so true? I know some people stuff their ports with socks, not sure what that accomplishes or why they do that. Seems odd though, like it seems like something the manufacturers would not recommend.

I know I can change the overall treble for all the speakers, not certain if I can set the treble for just 1 speaker though. So this is a limitation of the speaker itself? Is that why you upgraded from this speaker when you had it by any chance? Did you upgrade from it due to muddiness or brightness, or both?
Unfortunately, I just purchased this center speaker so my setup would be timbre matched. I have 6 N24II's that needed the matching center, so, I'm hoping I can make due with these speakers for a couple years. Hopefully there is something I can adjust on the AVR so it's not so sharp on the highs. If not, I'll have to lower the volume of the center channel I guess, but I imagine this option would not be optimal. (lowering the center channel volume).
This center is over 10 years old but I purchased it very recently and it supposedly has never been used (previous owner mentioned it sat in a closet for 10 years or so and I must admit it does look like it's brand new and perhaps the brightness is because it has truly never been used until now). That said, could these highs that are too piercing be a side-effect that could subside once the speaker is 'broken in' for a bit?
The reason I asked about the highs being too sharp and the possibility of it subsiding is due to a post I read where someone had an N-center (or ii) that was 'too bright' at first, but then after a while something 'loosened up' and I'm guessing stopped some of the brightness (too much treble / highness).http://www.hometheaterforum.com/topic/167919-anyone-using-jbl-n-center-ii/"I have been using an N-center along with 6 N24's. I could not be happier with this setup. The N-center in particular is a great speaker for the price. It can be a bit bright at first but once everything loosens up the brightness really diminishes."
It would be nice if this happens for me as well. If there is a possibility of this center speaker losing some brightness after being used for a bit, how long will it take? (I watch about 4 movies per week)
Would it be beneficial for me to play some music through the speaker for several hours every day or something to speed up the process? It also sounds like my room can be too bright as well, probably exacerbating the problem.
I've read a few interesting threads about speaker brightness, but it seems like I have a lot more to learn:http://www.avsforum.com/t/473714/what-does-it-mean-when-a-speaker-is-bright
Also, are today's speakers in the same price range a lot better sounding than the n-centerII? Just curious. When this speaker came out 10 years ago, it was in the $150 to $250 range I believe.
