so, i was wondering if it was worthwile/advisable to tinker around with the tuning of the JBL 4642A (dual 2241) cabinets....
I was thinking of something along the lines of the custom cabinets that Mr. Widget had built for our friend Scott Fitlin (RIP)
I am aware of the different woofers being utilized, and the difference in the number of ports per woofer... but figured I may be able to dink around with this sort of thing a little bit...
Another unique feature that we employed was to make the cabinets user tunable
...
There are two ports per woofer chamber and we have supplied two port lengths. If two long ports are used the speakers will have maximum VLF power and low bass extension. If two short ports are used the bass becomes punchier but at the cost of VLF. It is also possible to use one long and one short for an intermediate tuning.
