Hi,
Does anybody know (had measured) the port frequency in original JBL L100 monitors boxes?
Thanks,
Alexander

An original L100 (with the LE20 tweeter), has a 2" diameter vent in the front baffle, with no tube (1" vent length, due to the 1" thick baffle). This gave a tuning frequency of right at 41 Hz.
The L100A (with the LE25 tweeter, and the "elbowed" vent tube) had a vent frequency of right at 31 Hz.
Regards,
Gordon.
