I think I have a damaged or blown tweeter in one of my RT7's. The model number for that particular tweeter is SL-6501 but haven't been able to find it. The store on Ebay has a ton of tweeters but not the exact one. Is it okay to replace the tweeter with say an SL-6503 or 6509? Should both tweeters be replaced with either of those to keep the sound balanced. Thanks in advance.
