Great sound

poor quality

We purchased 2 sets of RT20's for our two home theaters. We have had all the subs and most of the mids go bad in these speakers. Actually all the drivers mfg in Oct 96 went bad. We do not listen to loud music, mostly movies and classical music. Polk has replaced these with their 5 year warrentee, but are getting reluctant now to do so even though with some talk they have done it. I really like the polk sound, but I'm worred that the rest of my speakers will go bad. We have 4 RT20's, 4 RT16's and 4 RT12's. I think I would think twice before purchasing more Polk.
