Aren't these subs designed for a ported enclosure? What size does the box have to be? Or will sealed have better SQ?

Where can I get info on these subs? I'm having a hard time finding stuff online.

The user manual can be downloaded here: http://www.focal.tm.fr/gb/instal/ima...butopia_gb.pdf

They seem to recommend a 1.4ft3 ported enclosure.

WinISD has the t/s parameters.. I can post them if you want.
