White Lightning Posted July 21, 2012 Report Share Posted July 21, 2012 P.S. they are single 4 ohm coils and 10" subs so final load would be 2 ohms obviously. I have a Fosgate T1000bd that will be powering them. I almost considered wiring them at 8 ohms, but I can't imagine the amp puts out a lot at 8. Might be worth a shot just to see \My apologies ... my question was answered here ...

CleanSierra Posted July 21, 2012 Author Report Share Posted July 21, 2012 So I know you run an external port, but could I try it with a slotted port? I have plenty on airspace, should I try designing a 4th for flatter response? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
CleanSierra Posted July 21, 2012 Author Report Share Posted July 21, 2012 BTW, I wasn't thinking obviously when asking about the other driver and displacement. If it's a push/pull, obviously it's inverted, it wouldn't affect the displacement. Im not the one you want to try to troll. Just a fyi for you.

I refer all my enclosure builds to Jimmy Walker (aka Linear Power's Thunder) ... but yes, flattest response possible ... I'm assuming you can run the ports any way you want, like I said a while back, I did not design my enclosure ...

Tuning should be around 24 to a max of 28 htz for this thing to perform correctly ... This is NOT going to be your average SPL enclosure design ...

john253a Posted July 22, 2012 Report Share Posted July 22, 2012 At 28hz it barely breaks -3db If you model it at 35hz it holds @0db from 40+ and a -3 of 30 So idd say I never missed the point Link to comment Share on other sites More sharing options...
JeremyN Posted July 22, 2012 Report Share Posted July 22, 2012 the long and short of an isobaric set up is all the weakness of the single sub are balanced by the other sub and the result is the tightest cleanest most accurate bass you'll ever hear ( if done correctly ) not the loudest but the cleanest 2 12" Jeff Vue Customs 1 set MB Quart FSB 216 in doors1 American Bass 100.1 on sub1 Hertz EP2 on doorsJVC deck IPOD controlStock 105 amp alt DD-1big 3new build in Chevy caviler http://www.stevemead...chevy-cavalier/last set up in the ZX2 http://www.stevemead...-current-build/old build log http://www.stevemead...-1998-ford-zx2/ Gold is the money of kings, silver is the money of gentlemen, debt is the money of slaves.

CleanSierra Posted July 22, 2012 Author Report Share Posted July 22, 2012 I'm not worried about building it incorrectly. I'll be planning the enclosure TONS before a saw or router ever hit any birch. The only real reason I'm considering the Iso setup is because I know these subs won't give any crazy output. However, even though they aren't output monsters, they seem like they have the ability, in the right enclosure, to get some GREAT requency response. I think they will be able to accurately dig into the 20s and still maintain some good sound into the 40s. I think maybe low 30s tuning so I can make sure my mids pick up the slack after the subs roll off. Im not the one you want to try to troll. Just a fyi for you.

john253a Posted July 22, 2012 Report Share Posted July 22, 2012 The only way I could get it below 30 was freeair, With cabin gain you may get there, You'll still play >30hz but below -3db To me that still fine to some they arnt happy with that Link to comment Share on other sites More sharing options...
