Post Number: 166 Registered: Aug-05 | you think a 5.75" 33.12" long port will be good enough for a 15" sub with 40mm xmax. if i don't mess with the bias it will be 36mm xmax which i probably won't change or i was thinking a 8x4 at 41.32" long L shaped port.. what you guys think oh the ports tuned to 25hz <~~~ cuase what was recommended.... also a brutus 2005d for sale $200+ shipping lol |

Second, try to get at the very least 12-14sq inches of port per net cuft of box. (16sq inches+ if you have the space) 1 15" for daily (in general) would be good in 4cuft net w/ 60-65sq inches of port ~26-30" long. (that will tune to 33-35hz) |

Silver Member Username: KravenbloodOhio DD Z1 you wi... Post Number: 168 Registered: Aug-05 | Cerwin vega stroker pro 15, Going to be pushed by a ddz1 @ 4 ohm for awhile then @ 1ohm, Anyway the recommended box size is 3 cubic feet after port and woofer displacment, since the port is outside of box i only need to add the woofer displacement and its going to be tuned to 25 hz.. so the box will be 3.165 cubic feet...A 6" port will be 36.25 " long which might be doable.. 2 4" ports are 33.20" long which might be doable also.. What you guys think |
