IH8PunkRok Posted September 21, 2010 Report Share Posted September 21, 2010 im trying to find a new box design for my 3512 (PB 3k for power) 1st idea: standard bass reflex but this time with about 20^2" per cube, 2.5 net volume, 35hz 2nd idea: 8th wave t-line @ 35hz 3rd idea: 4th order, 1 cube sealed 2 or 3 ported, not sure on tuning basically i need the box to gross about 4 cubes (just to make it fit) my dimensions are 14hx34wx15d ^ those are rough estimates btw might be more thoughts, ideas, comments, advice, designs? let me know guys obviously i want it to be loud on the meter but i will not sacrifice my music for a number. -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
OBI Posted September 21, 2010 Report Share Posted September 21, 2010 I vote for 4th order. Or just for shits in giggles try a normal ported but with something crazy for port, like 25sq inches. Link to comment Share on other sites More sharing options...

IH8PunkRok Posted September 21, 2010 Author Report Share Posted September 21, 2010 will a huge port create unloading problems or no? it makes sense that it would. however bkolfo says that the port area is based on woofer not box. i know that like 75" is less than what the max port area i could have is. therefore i may be safe. id assume my f3 would be a lot more sensitive though -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...

Also try getting ahold of 8 0inches, or singer. Im sure they could come up with something for you. Link to comment Share on other sites More sharing options...
Boon Posted September 21, 2010 Report Share Posted September 21, 2010 Do a DD box. Simple, effective. Or a 6th order. Don't do a phase box, DD's don't like them. Well, they only like bass-reflex horns. 4th order = best box ever for a musical 2500 but not for a 15/35/95 10.x volts fo' life! Link to comment Share on other sites More sharing options...

Boon Posted September 22, 2010 Report Share Posted September 22, 2010 What's wrong with your current box? I've found that the DD design is a damn good compromise between output and quality. Anywhere from 12-18 inches of port works great. Since you're running plenty of power you could possibly decrease the box size and increase the port area a little, basically what you're suggesting, but I don't think you would gain much. Slightly under 2 cubes would work well IMO. 10.x volts fo' life! Link to comment Share on other sites More sharing options...
