Silver Member Username: Sinful_systems7015 INCH WANG... Post Number: 994 Registered: Nov-06 | 2.2-2.5 cuft tuned to 30hz is my suggestion. Sub up port back! |

Bronze Member Username: Shak180Hayward, California Usa Post Number: 97 Registered: Jul-07 | I want sql. If i cant get that from this sub then i just want spl. its going to be in my daily driven car Also sinful sysytems why do you say sub up port back ? What difference would it make from sub and port being on the same side ? |

Bronze Member Username: Shak180Hayward, California Usa Post Number: 99 Registered: Jul-07 | isnt 30hz a pretty low level for a 12 inch subwoofer? or is that what this sub is capable of im just kinda stressin cuz i waited to the last minute to ask and the guy im having make my box is waiting on my specs and im getting ready to tell him 2.5 cubic ft at 30hz but that just doesnt sound right unless someone else agrees with sinful |

Silver Member Username: Shak180Hayward, California Usa Post Number: 101 Registered: Jul-07 | i went on memphis's website and for a single vented enclosure they recommend 4 cubic feet ported to 36hz what do you guys think ? |

Silver Member Username: Shak180Hayward, California Usa Post Number: 102 Registered: Jul-07 | k i talked to a memphis audio tech and he recommended this enclosure to me and im going to run with it unless someone disagrees and has a beter recommendation 3.5 cubic feet ported to 40hz with a port dimension of 12.5 x 2.5 and 16 inches deep what do you guys think |

Silver Member Username: Shak180Hayward, California Usa Post Number: 106 Registered: Jul-07 | 40hz is that a good frequency for daily driven? Or was the tech just trying to protect his companies sub from being abused ? |

Gold Member Username: Sinful_systems7015 INCH WANG... Post Number: 1008 Registered: Nov-06 | 40 hz would be for SPL only and would not soud good, in my opinion, on music. I would go with 4 cuft tuned to 32-33 hz for some good SQL.. JMO |

I think it sounds best this way in my experience.. but like I said before, it really depends on the vehicle but it will most of the time sound best this way. JMO |

Gold Member Username: InsearchofbassPost Number: 7304 Registered: Jun-04 | im gonna say 36 hz and 3 cubes net since I know how small a neon trunk is I assume thats why Scott said that too and that would be a good sql tune for that sub........a box tuned to 40 hz just annoys the heck out of me |
