the EP-2500 is likely to produce the 750W you mentioned (Bruce) only with the dual 2 ohm configuration (in real world). I am even wondering if I should reconsider the amp choice
Well, the spec says 750 watts into 4 ohms (which is the resultant Znom of the dual 2 ohm coil driver wired in series). So the one amp in stereo would do both boxes. This doesn't seem like too bad an amp..... good bang for the bucks. Others would cost much more.

Concerning the port velocity, I will kill this 26m/s limitation by using a 10" port, 80 cm long, but in a 600 L effective enclosure
Yep, that seems to work. I stayed away from the 10" when I was messing around since it would demand the port is mounted vertically because of its long length and I was attempting to get a front mount (for no good reason). There's nothing wrong with a vertical mount (I don't think)....
