Correct, you have the BLAM 5.25" and 6.5" - Micro Precision Tweeters.
@Apparition and @Tristar_tj recently added the BLAMs.
The tweeters make an astounding difference, probably the missing piece of the puzzle.
I ran it without them for a while and with them included you can hear the highs and mids on another level. In fact, that's what's so impressive about this setup is that the highs and mids are so pronounced that there is such clarity to the music. It's hard to put into words, but everything is just so crystal clear it sounds like I'm sitting in the front row at a live concert.
