Hi all. I'm sort of thinking ahead, and I see that the Polk t15 shares similar drivers...same tweeter and woofer. My question involves the tweeter. I've seen on older posts that replacement tweeters are about 100 for 2. If these two models use the same drivers, can they be used as replacements??
My Setup: Denon AVR X3600h, Polk Signature S50 Fronts w/ S30 Center and S15 Rears, LG UBK90 4K Player, TCL 6-Series 65”4k TV
