Phawstir Posted May 21, 2012 Author Report Share Posted May 21, 2012 (edited) Thanks 412, back to your statement on shooting for 3.5 cubes net...I realize that I have low power, but that seems like a loooooot of volume. Manufacturer specs are ported box volume: 1.5-3.0 cubic feet, with an optimum volume of 2.25 cubes. I am unsure about this, as compared to your knowledge of box design and building. Edit: poor choice of wording Edited May 21, 2012 by Phawstir Quote 2000 Jeep Cherokee 15" Alpine Type R box build coming soon! Link to comment Share on other sites More sharing options...

Edit: poor choice of wording This is based on using the recommended power to the sub as well. Since you are running low power to the sub running a larger enclosure will let the sub move more freely without restriction.

412 CVX Posted May 21, 2012 Report Share Posted May 21, 2012 anything below 2.5 cubes for a 15 is ridiculous. shoot for at leeeast 3 cubes. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

john253a Posted May 21, 2012 Report Share Posted May 21, 2012 I also agree hence going a bit bigger with the box When designing a box for slot port 14-16sq" per/ft is what you are after Also with a slot port try to not go over 9:1 ratio the closer to 1:1 the more efficient, The more efficient the smaller you can have a port hence aero a at 9-13 per ft My self I like my ports in the high 14 but thats me If I were you 2.5-3cuft 14-15sq" Per/ft of port Quote Link to comment Share on other sites More sharing options...
Phawstir Posted May 25, 2012 Author Report Share Posted May 25, 2012 (edited) How is this lookin' then? Edit: Also, my woofer mounting depth is a sliver under 9 inches. if the ass end of the woofer is pointing towards the port wall (along the internal back side of the box), there will only be just over an inch of gap between the magnet and port wall. Is this acceptable? Edited May 25, 2012 by Phawstir Quote 2000 Jeep Cherokee 15" Alpine Type R box build coming soon! Link to comment Share on other sites More sharing options...
412 CVX Posted May 25, 2012 Report Share Posted May 25, 2012 Do you listen to a lot of chopped and screwed music? personally i'd shrink the port area to around 14 per cube, and raise the tuning to 33-35 hz so you can still pick up some of the higher notes.

Phawstir Posted May 25, 2012 Author Report Share Posted May 25, 2012 No I don't. Ideally, I'd like this box to slam some lows, but still be musical for rock, metal, and other genres. Anything is going to be better than my 42hz tuned prefab in use at the moment. Thanks for the advice 412 you're really helping me out. I'll go see what numbers I can throw together. Any other advice would be much appreciated Quote 2000 Jeep Cherokee 15" Alpine Type R box build coming soon! Link to comment Share on other sites More sharing options...
AB18VFL Posted May 25, 2012 Report Share Posted May 25, 2012 this is what you want. you're underpowering the sub, so a bigger box should give you the best output. usually a smaller port area will sound a punchier for your metal and rock, Quote SUBSCRIBE AT YOUTUBE! 18abVFL < CLICK!! 2005 Subaru Impreza My build log.

Phawstir Posted May 25, 2012 Author Report Share Posted May 25, 2012 unless I'm wrong, you forgot to change the port height AB18VFL. Thanks for your input, I'm trying to balance quite a bit and with this being my first ported build i want to make sure I'm taking steps in the right direction. I listen to pretty much everything. For sure a good chunk of dubstep and rap/hip hop, but i still would like some musical capability for other genres, though they get a slight bit less playing time in my Jeep Quote 2000 Jeep Cherokee 15" Alpine Type R box build coming soon!
