I have an 8 cu.ft. box that I want to mount a JBL 2241 or 2242 in. I want to use it for some low end (sub woofer) assist with a smallish PA.
JBL recommends a 10 cu.ft. box, tuned to 40Hz, requiring 6 4" tubes 5.5" long for either of these drivers.
1) What tuning freq. should I use?
2) How many 4" tubes and how long should they be to tune either of these drivers properly in my 8 cu.ft. cabinet?
I could build a box port instead of using 4" plastic tubes, so I guess I need a number for the cu. in. required in this cabinet.
Thanks in advance,
Tom
