F-15, E-15, or F-15 HP?

For a 1700 cu ft room. Doorway openings to 920 cu ft and 945 cu ft rooms.

Will the extra headroom the 600w class H amp and higher excursion driver afford be worth the extra cost?

And what happened to the matte black finish? All I see now are Piano black (like it, wife hates it) and black oak (bleah!) on both the Rythmik and Ascend sites.
