Dangeruss Posted May 11, 2019 Report Share Posted May 11, 2019 I have a 95 mustang gt convertible. My plan is to run 2 skar vd-12 2's in the trunk. I want to build 2 fiberglass enclosures one left and one right tucked up in the quarter panel/wheel well area. So my current thinking is too build out one as test piece/ mock up. Then fill it with water to measure the internal volume. Then figure a port design for it. Im shooting for somewhere around 1.25 cf to 1.5 cf. And tuning it for around 35-40 hz. Anyone have any better ideas how to measure the volume of very irregular shaped box? Any suggestions on port design/location? Im probably stuck with a round tube port. Im guessing 2.5 in dia about 5in long. I have a 3d printer so I can pretty easily make a mold to build a venturi port out of fiberglass. Link to comment Share on other sites More sharing options...

Dangeruss Posted May 12, 2019 Author Report Share Posted May 12, 2019 Thanks, seems like there is not much interest in this topic. Maybe, just nobody really does this kinda thing. Link to comment Share on other sites More sharing options...

Yes, peeps are interested, but something like this requires more “hands on” rather than giving advice over the inter webs ...

Dangeruss Posted May 13, 2019 Author Report Share Posted May 13, 2019 This is the area Im working with. The speaker will sit in front of the tail light aimed toward the center of the dash. The port will be up by the fender well pointed parallel to the speaker. Im going to re-do the wiring thats in the way to try and get as much space as I can.

CstrokerV Posted May 13, 2019 Report Share Posted May 13, 2019 Try using tape then filling the area with packing peanuts get something you know how big it is then transfer the peanuts into that and calculate it that way my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...

Dangeruss Posted May 13, 2019 Author Report Share Posted May 13, 2019 Packing peanuts is a good idea. I'm playing around with some ideas on how to cut out the center of my speaker rings out after the box's are done. Im thinking cutt almost all the way through, leaving maybe a 1/16th of an inch. Then using my dremel to finnish them when I have the volume sorted.So far filling them with water is the best idea I can come with. Doesn't add much work either. Just have to give the speaker rings and the base of the box a coat of resin so they are water proof ahead of time. Packing peanuts should get me close enough to get the diameter of the port tube. So I can make rings to mount them.Then use the number I get with the water to get the lenth right. Any thing I need to look out for with making port tubes that have a bend in them? With such a small box would a smaller dia shorter port tube be better or larger longer tube? Link to comment Share on other sites More sharing options...
