Great sound but time consuming install
I used these speakers to replace damaged tweeters in my Polk tower speaker housing (R50 T09136) Tweeter (RD6516 1/4). The screw mounting holes match up, however you will need to enlarge the hole to accommodate the larger magnet ( drill & saw). The speakers are a nice up grade and are more heavy duty. I would buy them again even knowing additional labor is required. Cheers!
