Sub Box Large Enough?

[1989 Lxi Coupe]

I think I might be running a box that is a little to small for my sub. I want to make sure. I've been running it for a few weeks like this and it seems to hit pretty well and sounds very tight. I'm about sound quality. I listed my sub stats and box below...

Eclipse SW8102.4 (500watts RMS getting 300watts RMS)

--------------------------------------------------------------------------------
Fs: 22Hz
--------------------------------------------------------------------------------
Qts: 0.41
--------------------------------------------------------------------------------
DCR: 3.1/coil
--------------------------------------------------------------------------------
Vas: 2.94 cuft
--------------------------------------------------------------------------------
Xmax:
(one way) 1.20"
--------------------------------------------------------------------------------

Box: 3/4 Dual MDF, 15"D(bottom)x 9-7/8"D (top) x 12-5/8"H x 12-5/8"W, 0.71 CUBIT FEET (Sealed Angled Box)

What does Vas mean? Thank You.

your box is too small. with all my subs i run about 1.5 cubic feet or 2.0. all my subs sound smooth and clean. so yea.

VAS = Volume Air Space. if you would like ill build you a box for your sub and send it to you. just pay for wood and shipping.
