Driver for cyclops CBx-18

Hi Everyone.

I'm building two cyclops CBx-18 subs. I'm in New Zealand so we don't have quite the range of drivers available as the US or Europe. Our local pro audio supplier has Eminence - OMEGA PRO-18 4 Ohm drivers for sale at $920 NZD (~$650 US) $2K NZD This is about my maximum budget for 2 drivers.

Eminence - OMEGA PRO-18 4 Ohm — Livesound

My question is; is this a suitable driver for a Cyclops CBx, or is there something better and worth taking getting shipped from the US.

thanks!
Matt
