I just built 2 seperate boxes to maximize my space and they are for 10" Punch. I went to 12 volts site to see what was the volume of these and now i THINK i MAY Port them... I have .80566 as the volume per sub in the enclosures, How big should my port be? I am pushing them with a Punch P3001 rated power is 300 W RMS x 1@2 OHMS... how do I figure Hz to get the size and length of the ports? HELP ME PLS ------------- Thanks ALWAYS for the help

.80 cubic ft? That is way to small of a box to port.

Use the sub manufacturer's exact, specific size requirements if you want to port. They will tell you what to use. You can look up your model here. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Thanks for the help guys... If i port them yes they are too small however a sealed looks like they are too big...is that a problem on sealed boxes? Will .15 be a problem for the speakers on a sealed box?

A box that is too big can be filled to the right size. Double panels, put in bracing, glue in a wood block, etc. Do a lot of measuring, and get it to the recommended air space.

ok cool but what does it do to the speakers being too big... just laymens terms...will it freeze the voice coils? will poly filling it help take some space?

Poly fill will actually do the oposite, you wanna use a wood block
