I own the crystal ssx 6's and they sound great. I have them in fiberglass doorpods and the midbass is quite impressive. But then again I only have 40rms going to them. The tweets dont get too harsh, but I have heard a few songs that were too much for me at high volumes. I would definatly recomend them. And if the tweet is too harsh you could make your own crossover and buy a nice set of silk domes. They have a lot more potential for midbass even with my profile that puts out 50rms, but the PG is just sooo much cleaner.
