Both are roughly 2yrs old, so these do NOT have the new heatsinks or updates xovers like the 100.4D or the extra heat sink in the newer 1500D. The Plus side of all this though.....always used in a pure SQ setup. The 1500D has NEVER been run below 2 ohms..EVER! There is a couple of nicks and scratches but they are very presentable. I would rate them at a 9/10. For reference, they were used by my wife to take home the MECA Stock Class CA state championhsip.
$500 for the pair or $325 for the 1500D and $275 for the 100.4
If you buy both as a set I will toss in a Bulk pack of Damplifier Pro for an even $600.
I will not lower the price so dont ask.
