charli3 Posted September 20, 2010 Report Share Posted September 20, 2010 I have a dc lvl 4xl 12". I have a 1.7 cubic ft box and was wondering what size port tube and length to put in it to have it tuned around 30-35. I used the calculators but i dont think i was doing it right so id just like some help from people with experience. Quote Link to comment Share on other sites More sharing options...

dohckiller808 Posted September 20, 2010 Report Share Posted September 20, 2010 is 1.7 your max gross you can go? or is that what your aiming for net? Quote Link to comment Share on other sites More sharing options...
Robert8252 Posted September 20, 2010 Report Share Posted September 20, 2010 Is your box volume 1.7 before or after sub displacement of .19? I used two 3" flared aeros for mine. I have a tad extra port area then normal I think though but if you haven't built the box yet it may be easier to do a slot port to get the tuning you want. Its just kind of hard to get the box deep enough to use the right port unless you can use an external aero port..

charli3 Posted September 20, 2010 Author Report Share Posted September 20, 2010 its 1.7 before the sub was put in so im not sure the exact volume now. its a prefab box with a tall rectangle port thats maybe an inch wide, on tones of bass that seem to be really low the sub just throws out air biskets without making alot of noise at all but tons of air comes out the port but it seems not enough air can pass through for it to sound right. So i wana block the slot port and put aero ones in. I have no clue on tuning a box so any help is really appreciated. Quote Link to comment Share on other sites More sharing options...
Robert8252 Posted September 20, 2010 Report Share Posted September 20, 2010 If you're running a XL you REALLY need to consider making a custom CORRECT box for it.

charli3 Posted September 20, 2010 Author Report Share Posted September 20, 2010 I cant build boxes myself either but a guy down the road who builds cabinets has built me a few sealed enclosures, but i dont think he would build a ported one. So if the box size is wrong he could build me a new box of a different size and then i could put whatever size port tubes in it. Quote Link to comment Share on other sites More sharing options...
bassl0va Posted September 20, 2010 Report Share Posted September 20, 2010 If he can build sealed boxes then he could build you a slot port. But if you wanted aeros then yeah, just get him to make a box, then you cut the holes.

charli3 Posted September 20, 2010 Author Report Share Posted September 20, 2010 Alright what size box should i have him build tomarow and what size ports should i order. I wanted to have a box built by a sub shop but when i told them it was a dc sub they started ripping on me saying it was a cheap ebay sub, they didnt know rob dyrdek was making subs now, and that my only problem was that i needed a new sub. Their pretty big too i beleive there called Sub Zero Sounds in MN. Quote Link to comment Share on other sites More sharing options...
Dub7Banger Posted September 20, 2010 Report Share Posted September 20, 2010 (edited) Alright what size box should i have him build tomorrow and what size ports should i order. I wanted to have a box built by a sub shop but when i told them it was a dc sub they started ripping on me saying it was a cheap ebay sub, they didn't know rob dyrdek was making subs now, and that my only problem was that i needed a new sub. Their pretty big too i believe there called Sub Zero Sounds in MN. Call me retarded but uh....I don't think Rob Dyrdek has anything to do with DC Sound Labs? And to the OP, I'd PM and ask Rob (Thorshammer) the best ported enclosure size for the XL 12. The website states 6cf for a Level 5 18, but he told me to shoot for 5.5 after all displacement. Once you do that, you know what size to aim for using the Torres calculator, then just get the woofer displacement, (which I believe someone stated was .19cf), then bracing displacement, (Just as a random fyi, a single 12' 2x3 is .5cf, that ought to fit most bracing needs) figure out what thickness to do all around, figure out your baffle thickness (Are you gonna double up? I would) then work out a slot port, and if that doesn't work out the way you need it to, use aeros. (In most cases will take up less box volume) EDIT!: Ok now I got myself thinking. DC Sound Labs and DC Shoes/clothing/etc are NOT the same company are they?

Don't think about it, just do it. It'll work. go to lowes get bricks wait in yard. throw said brick at vehicle. If thats me and that just happened to me Im going looking for him after that. 1. Goto lowes 2. Get some bricks 3. ??? 4. PROFIT!! Profit from everything. LOVE ideas like this. xD Link to comment Share on other sites More sharing options...
