They do get pretty loud(the KS25s are 1") and tuned they are clean as well.Kicker does make a 3/4" Titanium but I have not ever tried those.But I can Vouch for the KS25s, as I run them,and have in the past,and they do excellent for me..They lasted longer and sounded much better than even the JBL Titaniums (which seem to produce a muddy hiss that I could never get rid of).I had some in my truck. They were really loud for how small they were.
