The list price may be $600, but I got them at InfiniteCarAudio.com for $200, and they carry the full line. Not sure why, but notice the MS5 5.25 model are $50 more...You can read a review that is linked from the DLS site, two pages:

they sound great, but not as nice as my bro's Iridum 6.3's //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gifmid bass is nice and clean, no distortion
They go really loud before you can hear distortion in the tweeter.
its to loud at that volume level anyways
75rms is geat
unlike CDT, DLS' dont need 200+ RMS to sound good
