I have never owned a set but after hearing several sets of the components (Honestly I have heard them in about 8+ installs, Bob Perrillo's Van, Jared Horton's Golf, Mike Travassos's Explorer, Tim Roy's Van and etc). The tweeters are extremely harsh and noticable break up between the mid and tweeter. I am in no way saying this to down T3 Audio because I have personal ran there subwoofers and I must say the TSS is great driver. I have owned and installed several of them and would do it again. I have no experience with the coax though.
