I want a vented box for a the new 12" Alpine Type R sub (SWR-1242D). The box is the QLH-12512SS. Tuned to 34Hz, 1.25cu ft. Get all the info here: http://www.cardomain.com/item/QLCQLH12512SS . The only problem I see with this sub is that it is 5/8in MDF on all sides except front, where they say it's 3/4in MDF. Not too many people have talked about this sub, so I need some opinions. Thank you |

Bronze Member Username: KoojoPost Number: 22 Registered: Aug-05 | Well I dont want anything fancy. Two 1" walls is insane, and will probably weigh a ton. I know most people go with 3/4" MDF, so I was wondering how 5/8" MDF would be different. |

Bronze Member Username: KoojoPost Number: 23 Registered: Aug-05 | Oh ok, that's what I was going to ask. Do I just buy some board and add it to the inside? That would just decrease the cu ft though right? Maybe remove the carpet, add some board to the outside, and then recarpet it? Not sure how its done. Thank you. |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 794 Registered: May-05 | i guess my point was that i prefer overkill to an inadequate box. i had a similar one and was very displeased. much of the sound that my subs was producing was being transferred to the box via vibration. in addition, i had to go back and reseal the enclosure. it isn't well constructed. i don't think many prefab boxes are at all but certainly not the q logic. i would sooner go this route, but that's just my take. http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=260-692 |
