THEKINGsBACK Posted June 16, 2009 Report Share Posted June 16, 2009 I just ran out and looked at the back and thought and measured and figured this is better. The port runs down 11in. port and sub face up. A MAN WHAT PROGRAM DID YOU USE TO GET THAT MEASUREMENT>>> LOOKIN TO TRYIN OUT A NEW ONE Quote he wouldnt be the first to say they did a 167 with a system like that (one that clearly DOESNT), but i have to say, he didnt beat me anywhere, ive never competed against the guy. If he thinks his does a 167, mine would probably put him in a coma. :hairtrick: Link to comment Share on other sites More sharing options...
Jville140db Posted June 16, 2009 Report Share Posted June 16, 2009 (edited) ?? no, even with the use of a slot port, i get a length of about 35" for the tuning to be at around 32 hz. yeah sorry about that reran the numbers and came up with 34in length 32.04 hz the 18in length will give you 38.29 hz but i did not take into account any bracing just the sub im using bass box pro 6 for the record Edited June 16, 2009 by Jville140db Quote Car is 2010 Scion Tc Currently in car Deck- Sony XAV-60 in-dash mobile video system Speakers- Rockford Punch 6.5in comps in the front and coax in the rear Subs- 2 Gen 3 Rockford P3 12's dual 4 ohm Amps- Rockford P1000-1bd and P400-4 Alpine Mrp-f300 is in for P400-4 which is out to service Wiring- all rockford nuff said Enclosure- Dual 12in custom box by SRQ Battery- Optima Yellow top with big 3 done Sound Damping- All Dynamat products 1-2 layers throughout with liner on top Link to my build log- http://down4sound.co...=newpost&t=5275 Link to my youtube- http://www.youtube.c...ser/Jville140db MECP Advanced CEA # 110531 BassBox 6 Pro for Box Building/Re audio box calculator If you can hear the passenger it aint loud enough!!!!!!!

Torres Posted June 16, 2009 Report Share Posted June 16, 2009 I even used your calculator and that's what I got. Then I used one from Alpine and theirs said like 19.5. So my results from the two were 18" and 19.5" your height and width are in the wrong spots. you need to switch them. if you're using a slot port with 22.5" from the box wall to port wall, it's adding in 11.25" for end correction. when in fact it should be 4" for height, adding in 2" for end correction A MAN WHAT PROGRAM DID YOU USE TO GET THAT MEASUREMENT>>> LOOKIN TO TRYIN OUT A NEW ONE it's mine. it's in my sig I don't understand... I run these damn numbers 100 times and I get what I am looking for and you run them and get something way off from me...getting aggrivated switch the height with the width and you should be good Two different programs... two completely different calculation methods I'd assume. even so, the end result should be the same if the formula was executed correctly. seeing as how he had his numbers switched, i think they're both ok really Quote Link to comment Share on other sites More sharing options...
