i'm using the "magic tempest box" but i have a few questions. does shape matter when building a box? in order to fit a 4' cubed box into my trunk, i have to make the box long and narrow at 32"x18"x12" (the 12 being the depth, and the side the sub is mounted) As long as i have the vent clear and in the middle of the box (with one 90ยบ turn) will this shape affect performance? with no experience with enclosures, my thoughts are that the shape won't matter. it's not the speed at which the air "flows" in the box (the air from one side taking longer to get to teh port, becuase of how long the box is), but the air presure (the air presure would be the same everywhere, no matter the shape) Is this correct? will a long and narrow box sound different than a perfect cube?
Correct. Shape will not matter, but for reinforcement reasons I reccomend the port and driver be on the same plane.
what do you recommend when building the box? i have the wood and PVC. i was just going to "screw em all together"
My boxbuilder tutorial. Should provide all the information you need for it's construction including suggested materials. There are also some good simple tricks in there no matter what tools you are using for it's construction
thank you, but the link didn't work for me. all i see is a sounddomain title and then the rest is white
Always use screws and glue. Functionally, the screws are simply little clamps that first help hold the joints together tightly while the glue cures. Also, use 1 5/8" drywall screws... And pick up a #8 countersink/drill bit. This little nifty gadget saves time like no other.. it predrills your holes, and counterbores a seat for the screwhead, in one pass. B) I recommend using Titebond brand glue, it's weather resistant, it won't degrade in humidity.. cars go everywhere. And you might pick up some 100% silicone glue/caulk, so that after you are done building the enclosure, you can run a bead of silicone along the inside edges (joints), to ensure an airtight enclosure. Contrary to intuitive beliefs, the port actually creates a situation where there are higher pressure fluctuations inside the enclosure than a sealed box would.
