just a question before i buy

Sealed - 70 litres (2.5 cu. ft.)

Ported - 84 litres (3 cu. ft.) 28Hz tuning

do these include the driver and port volume, the driver looks huge, and the box volumes are so small

Those do not include other displacements. You need to figure in both to the NET amount.

hey thx that is exactly to the point what i wanted to hear..

Precisely. So, if you want to do a 3 cube net enclosure, make it 4 cubes gross volume. If you like the dimensional look of the test box I put together, the inside dimensions are 27"L x 16"H x 16"D. You can tune a bit higher - say 30Hz for that added bump if its going in an auto. For this, your port is 2.5" x 16" x 35" long.

wicked your last post should go into the sticky, ordering sunday night , looking 4 ward to a canadian driver nice work

good choice in drivers!
