I have a set of Polk Audio RTi A9 towers in my living room.. had them for over 2 years now. I started hearing noises coming from 1 of the mids... took it out of the tower, and took a closer listen and sure enough coil rub.
I'd really like to replace the mid ( 5 1/4" )... any idea what would be an upgrade from the factory mid? Or should I just go through Polk and try to get a new one?
I noticed that the mids move like crazy on the towers compared to the woofers, and also in comparison to the tweeters. Theres no EQ setting on my Onkyo for mids, only treble & bass, is there a way I could turn down the mids a tad?
Let me know if anyone knows any upgrades for mids or if I have to go through Polk?
