Good enclosure?

I was thinking of getting this enclosure...

Adrenalin Dual 12" Empty Bandpass Enclosure
·15" H x 30" W x 15" D

Does anyone know anything about Adrenalin? Do they make a decent box?
Im getting 2 12" Hifonics Titans btw.

You need to make sure the enclosure volumes are correct for the subs.

even more so, the ports have to be right too. You really need to have one made, or make it yourself.
