Is .85 cubic feet too small of sealed box for...
 

a Pioneer Ts-w3003d4 12" 2,000-watt Champion Series pro Sub-woofer?


My old Rockford Fosgate disintegrated and I've ordered the Pioneer unit, but it says to use a 1.25 cubic feet sealed or 1.5 cubic feet ported enclosure for optimum sound.
I'm wondering how it will sound in the existing .85 cubic foot sealed box?
