46panel Posted August 4, 2011 Author Report Posted August 4, 2011 just remember a box can never be to strong... MOAR LAYERZ! Yea I'd love to, but it's feeling pretty solid and still need to add the braces so it's going to have to be about good, and the money I don't have doesn't help ha. I'm mainly concerned about my port area. 1:1.75 ratio with 25 cubes ported space. I am thinking of doing like 450" of port area tuned around 40-43. I'm wanting this thing to get lowww so does that sound about right? 1946 Chevy Panel Truck: For Sale 1999 Ford Explorer XLT Subs: Ten Obsidian Audio 15's Sub Amps: Five American Bass 120.1's Speakers: American Bass mids and selenium tweeters Speaker Amp: Mb Quart Dsc4125 Electrical: DC power 250amp alt, 6 batteries http://www.youtube.com/user/46panel
matt402 Posted August 4, 2011 Report Posted August 4, 2011 yep itll get loooooow . i hope u meant 1.75:1 ratio... .
fecupe2001 Posted August 4, 2011 Report Posted August 4, 2011 Very nice progress man, i honestly think 450SQ of port is more than enough on your design if you ask me, specially if you want to play LOW as hell, bigger port would need more lenght and internal space of the port chamber would shrink even more giving you something like 1.5 : 1 ratio, with 1526" of cone area and a 42 hz tuning on a BP i wouldn´t worry too much right now because you sir are gonna move TONS of air!!!

46panel Posted August 4, 2011 Author Report Posted August 4, 2011 yep itll get loooooow . i hope u meant 1.75:1 ratio... . Sealed side smaller then ported so whatever way you want to look at it.

Yea that's what I'm thinking. The port is going to be on the outside of the box tho, so it wont' take up room on the inside of the box. 1946 Chevy Panel Truck: For Sale 1999 Ford Explorer XLT Subs: Ten Obsidian Audio 15's Sub Amps: Five American Bass 120.1's Speakers: American Bass mids and selenium tweeters Speaker Amp: Mb Quart Dsc4125 Electrical: DC power 250amp alt, 6 batteries http://www.youtube.com/user/46panel
46panel Posted August 4, 2011 Author Report Posted August 4, 2011 I think I'm going to add some polyfill in the sealed section. I should have 2.25-2.3 cubes per sub right now. Would rather 2.5-2.75 so maybe that will help make up for it?

matt402 Posted August 4, 2011 Report Posted August 4, 2011 id try it without polyfill 1st. ive seen 18s in as little as 1.7 or 1.8 cubes sealed.
46panel Posted August 4, 2011 Author Report Posted August 4, 2011 id try it without polyfill 1st. ive seen 18s in as little as 1.7 or 1.8 cubes sealed. Well it's already on. Just going to do that wall and call it good. It's just I'm not going to have a ton of power right away and want to make sure it gets low. 1946 Chevy Panel Truck: For Sale 1999 Ford Explorer XLT Subs: Ten Obsidian Audio 15's Sub Amps: Five American Bass 120.1's Speakers: American Bass mids and selenium tweeters Speaker Amp: Mb Quart Dsc4125 Electrical: DC power 250amp alt, 6 batteries http://www.youtube.com/user/46panel
