I posted a while back that the high freq output of my CS350LS is lower than my LS90's. I can tell this "by ear" as well as the EQ adjustments that my auto calibration mic wants to make for the CS350LS (+5dB at 11kHz).
Eric from customer service told me that they could modify the CS350LS' crossover to better match the LS90s' tweeter output.
Anyone have an opinion on this approach or have a feel for the specifics of what they would do?
I would assume that the inherent freq response of the CS350LS and LS90 tweeter would be very similar, since they are similar tweeters. So, I'm guessing that the tweeter output of the CS350LS is limited by a crossover element with a different value (different size cap or resistor somewhere). I'm thinking that changing this crossover element to the same value as the LS90s' would bring the tweeter output to the same level. I don't know much about crossover design, so I may be over-simplifying.
I plan to talk to Polk more about this, but also wanted to check the opinions of other CP'ers.
