I have an existing cabinet around 8.5 to 9.5 cu.ft. (depending on port volume, extra bracing, etc.) and would like some port areas and volumes that would tune a JBL 2242 to around 32 to 38 hz. I just want a moderate extension to use this with a small PA system as a subwoofer to help with the lowest octave.
Your suggestions will be appreciated!
Thanks,
Tom
