Posted October 9, 201014 yr Hello all, i have a question about a box design, i have always had beat in all my cars but i have never built a box before so this is going to be my first one, and i was wondering if this design would work or not, its going to go in a 96 blazer. thanks alot
October 9, 201014 yr a general rule is 12-16 sq in of port per cu ft. of box volume. lets say 14 sq ft. per ft. would be about 84 inches of port. your at 36sq inches..Also is seems a little small for two 15s ported. what drivers are you going to use? that will determine what size box and how much port you will need.
October 9, 201014 yr You need a TON more port, you have them modeled to run in a leaky sealed box, not a vented enclosure.
October 10, 201014 yr I'd double that area if I were you, use this calculator http://www.carstereo.com/help/Articles.cfm?id=31
October 10, 201014 yr I'm planning a build with a few of these subs and I'm hoping to give each sub approx. 70cu" of port per sub and from what I've been told that is still on the low side. Deffinately give them some more port area. Good Luck with your build and keep us up to date with what is going on with it.
October 10, 201014 yr I'd double that area if I were you, use this calculator http://www.carstereo.com/help/Articles.cfm?id=31This formula should also be taken in moderation too. There are many other things that play into port area, the most important: power. The best way to model port velocity is with WinISD. Andrew
October 10, 201014 yr Author Duran that dosent really mean that much to me, it looks like it made the port smaller
October 10, 201014 yr Duran that dosent really mean that much to me, it looks like it made the port smaller Go recheck that info with a 20mm Xmax, i beleive that is the spec on the SA15 and that will give you a completely different answer. With what you showed, and a 20mm Xmax it showed min. area at about 145"
October 10, 201014 yr Author oh ok i see now yeah i didnt know the xmax for them, now 145 is the min port area i need for the box right?
October 10, 201014 yr oh ok i see now yeah i didnt know the xmax for them, now 145 is the min port area i need for the box right?That's what is shows, but remember that is for min. port area, and ported at 35 may be a little high for daily.
October 10, 201014 yr Author the new saz-1500v.2, so i have some time to get the design the box before i start the build, like i said i have never built a box before and i dont really know how to figger it out or what i'm doing Edited October 10, 201014 yr by Davo2378
October 10, 201014 yr the new saz-1500v.2Wired @ 1 ohm that should hit pretty good if you get the enclosure setup figured out like you want. Keep askin' questions and the answers will come, we all want the mostest from our setups.
October 11, 201014 yr Maybe you can try round flared ports ? Ask Argent Audio or go to Part-express or Madisound for psp ports. You could save some space for your box.It's what I did, and I like it !!!
