Ok for my first fiberglass project i plan on making an enclosure for my 2 12 inch diamond audio d3's
I was most concerned with providing the correct amount of airspace for the subs...which i searched through the forum and found that packing peanuts are the easiest way to do so. Do you guys have any tips for accurately doing this...also if i put them in one single enclosure..which i have not decided if i am yet...should i make a partition out of MDF to create to seperate air spaces within the enclosure?
Also I know a ported enclosure allows your subs to respond better to lower frequencies. How do I determine the size shape and placement of these ports?
Any other general tips you guys can give me about fiberglassing would be greatly appreciated.
thanks in advance

Well the first place I would start is to make a cardboard box 12x12x12 on the inside. Put a line on the inside 6 inches from the bottom and pour the peanuts into that for measurements. The line represents 1/2 cf and of course a full box is 1cf. If you have the patience, I would recommend using as small a packing peanuts as possible, that will help maintain accuracy.

Refer to the manual/information that came with the subs for the size of the ports, shapes for the
most part, do not really matter so long as the proper vent area and length is maintained. As for placement, for the best quality in sound, I would make sure that the ports and subs are along the same plane as much as possible. That will help minimize phasing (assuming that the subs are mechanically in phase)

Be patient, watch out for air bubbles. If you get any of them that manage to find their way in after curing, you'll have to get rid of them in order maintain strength. The final thickness should be no less than 3/8 inch for strength. Curves are the best form that FG takes and maintains, try and avoid flat zones; FG tends to be relatively weak in flat planes.
An oh yes, the most important thing about FG: HAVE FUN!

You are very welcome. Please do not hesitate to ask any other questions, the only dumb ones are the ones you don't ask.
