I'm going to add my frustration with a couple of issues I had with Klipsch speakers over the years.
I purchased a pair of KLF-10s brand new in a military BX overseas in 1998 & they arrived with one of the woofers wired out of phase. It took me nearly 6 months to figure this out.
I purchased an entire RF-83 5.1 system almost 2 years ago and encountered the same issue, albeit there was ALSO one of the woofers completely unplugged inside. This sounds a lot like a QA issue with Klipsch's internal wiring.
Also, I agree that there is a LOT of plastic in the new Klipsch line. As long as they sound good & the plastic is of good quality, I don't have an issue with it. However, when they make the entire front of the speaker connected to the horn driver so you have to disassemble the entire front to take out the horn.
Also, the tabs holding my RT12d grill on broke during normal use....
THAT SAID....I notificed Klipsch & they have a new horn & grill shipped within 24 hrs!
