Default Aurum Cantus Drivers for First Project

This is going to be my first project and I want to keep it simple. I am a big Linn fan (my current speakers are Linn Katans) so my main design criteria are rythmic stability / transient speed and pitch accuracy. I do not want to go over $250 on drivers (I am assuming the project will total about 2x the driver price?).

After looking at a lot of drivers I think I want to try Aurum Cantus woofers with a dome tweeter in a simple 2 way. The choices are:

AC-180F1D: A 7" driver with dual voice coils (would i even know what to do with them?). It seems to me this driver would work well in a sealed enclosure making design easier in that respect. Obviously I will loose off axis smoothness, but probably have decent bass for a stand mount.

AC-130MKII: A 5.25 driver with carbon fiber/kevlar cone. This driver looks to me like it demands a vented enclosure which I think would be much harder to design. Probably better off-axis responce and can be crossed over at very high frequencies (from manufacture specs).

Tweeter will probably be Morel DMS-30 or similar.

I would apreciate any thoughts on the compromises that would be made in either case. Keep in mind that I am looking for bass quality and speed, not quantity. Also if you can think of any other drivers that would meet my requirements better then the ACs please let me know.

I really like the way these AC woofers measure in WinISD. The 130MKII gives very similar results in a 9,3l (0,33ft^3) vented SBB4 box than the 180F1 in a 23,6l (0,83ft^3) Qtc 0,586 closed box. I haven't heard any of these, but I really would like try to build something with them.
