AlpineGuy87 Posted February 27, 2007 Report Share Posted February 27, 2007 Well, I am interested in building a new box for my 2 - 12" Alpine Type R's..anyone have any build layouts or designs that i may or should consider?? This is my current box, with a port problem.. I'm looking for a box that is going to give me a lot of port "blow" like lots of air flow... ANY IDEAS WOULD BE AWESOME!!! If you have pics, would be even better!! Quote 06 SCION tC Link to comment Share on other sites More sharing options...
Mr. 973808 Posted February 27, 2007 Report Share Posted February 27, 2007 I've got some plans that I drew up a while back. I'll have to find them and send them to you. Quote THE GRADUATE 10:18:2007 Link to comment Share on other sites More sharing options...
sean 371 Posted February 27, 2007 Report Share Posted February 27, 2007 The port looks a tad small for one thing. I'm not sure how big the box is, but try to have at least 16 inches of port per cubic foot of port area.

Forevrbumpn Posted February 27, 2007 Report Share Posted February 27, 2007 That whole 16" of port area per cubic foot thing is only a guide line for SPL that DD Audio made popular. There are a few ways I determine port area, they are: SPL 50% cone area SQL 35% cone area SQ 25% cone area Another I just started useing which also works great, is get the QTS number, and multiply that by cone area. So, a 0.35 QTS sub with 80sq in area cone is 28sq inch port. As far as air space, I just work within the car environment, and use port length to calculate tuning- Subs under 0.20qts, or over 0.7qts, you may want to use other techniques Quote I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.
