I have used CDT since about 2004. I had a set in my Ranger with the DRT-25 tweeters. I loved those tweeters, but had to let them go when I sold the truck. I don't undeerstand why people talk bad about them. Then again, there is always somebody with something bad to say about everything. Currently, I am running The JBL tweeters that came with the MS-62c set. On axis, they are too much for me, but off axis, they sound good. I really like the way the high-hats and other metallic instruments have that extra impact to them.
