Bronze Member Username: NkknutsonPost Number: 74 Registered: Dec-06 | ok i have been looking and can't figure out cuft. lets take the Q15" for example it recomends 2.8-4.0 of cuft for a ported box. So what is the difference between the low and high number and would the same nubmer work for the BL sub. i plan on tuning it to 30 if i get the Q or the BL. |

They are telling you to expect to build a box at least 2.8 CF to get an average bass response, but for extended low frequencies, expect to build a box as big as 4.0 CF. "would the same nubmer work for the BL sub" The thiel parameters would have to be inputed into a few formulas to get your answer. Check with FI about the BL box expectations and see for yourself. It may work, but I wouldnt just build a box and expect to swap subs on demand. " i plan on tuning it to 30 " Tuning should not be decided based on what you want, but what the driver requires. You really should do more research before you build a box. I am certain that if you get educated on building boxes and how speakers work, you will be a lot better off than just doing what others tell you. Read this; www.bcae1.com |
