I seem to have an annoying problem with sibilance in my home theater system now. Is this a common trait with the RTi series (CSI5 Center) speakers?

    I can't speak for that particular speaker, but my CSi40 had some harshness akin to sibilance until Audyssey reigned it in. That said, if it's a new speaker, it will mellow slightly as it breaks in... but it could just be the AVR or amp you have it paired to. Different combinations produce different results.
    Equipment list:
    Onkyo TX-NR3010 9.2 AVR
    Emotiva XPA-3 amp
    Polk RTi70 mains, CSi40 center, RTi38 surrounds, RTi28 rears and heights
    SVS 20-39CS+ subwoofer powered by Crown XLS1500
    Oppo BDP-93 Blu-ray player
    DarbeeVision DVP5000 video processor
    Epson 8500UB 1080p projector

    Sibilance can be attributed to one piece of gear or a combination of gear used, or source material. When we say everything matters, we aren't yankin' your chain. Even certain cables can contribute or lessen the effect. Try taking the B&K out of the chain and just use the avr and see if that helps. That amp may be in need of some refurbishing.

    I use RTi8s and CSi5 w/ my Pio SC-25 and have no problems with sibilance that I'm aware of. I use those B-stock MIT EXP speaker cables..

    I have your exact speaker setup and havent ever had an issue. I even ran it off the same vsx1120 for a while without a problem, maybe it's the amp?

    I pulled the amp out of the loop and I still think it's a bit sibilant. I replaced my 16 gauge speaker wire with some 12 gauge speaker wire a while back and I'm starting to think it's to blame so I'm going to swap back to the smaller gauge and see if that's the cause.

    I swapped out my center channel's 16 gauge speaker wire and replaced it with the 12 gauge and I still notice the Sibilance. I even swapped out the HDMI cable. I'm beginning to think it's a trait of the new DirecTV box and some of the TV stations we watch like ESPN.

    Next I think I will swap out my left and right channel speaker cables and pull the banana plugs out of the loop also. I may also pull the tweeters from my rear speakers and place them in the front ones to see if that could be a problem.

    I'm starting to think I may have a crossover problem.:confused:

    I just put the MIT ExP2 speaker cables on my front 3 for my HT and I have already noticed a nice improvement. Less harsh, with tighter bass.

    They still have some of the 10' "B-Stock" pairs in stock, they are a steal for the price and a great way to get into higher end cables for a nice price.
