The Iridium 6.5 (and UR6 and UR6S) has a 3" voice coil... larger than the one you mentioned. DLS I hear uses Scanspeak drivers. How can you say the DLS is "simply this..." - except for this and except for that and except for this, and some other differences...100 watts is great -- Keep this one in mind the driver used in the DLS is simply this:http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=297-064
In a 4 ohm version, unpressed paper cone, 1/2 the Bl field (and 3dB/2.83V less efficient -- which makes up for the fact it is 4 ohms vs 8 ohms), smaller voice coil (less power handling)... and 6.25" vs 6.5" -- some other differences too. there are other options too btw than just those send me a PM if you are curious.
The UR6 midbass seems to be identical to the Iridium except for a poly cone rather than non-pressed paper... I listened to both of these in-car with an A/B test and their sound is VERY different. To compare sound and performance between 2 drivers with even subtle differences cannot be done without hearing and comparing them directly.
