JBL enclosure guide

[Squirrel]

In the JBL enclosure guide, does the tuned frequency indicated correspond to the lowest frequency reproduced by the system?
How come that the tuned frequencies are the same in a cabinet with either a single or a pair of 2245?
Thanks for your answer

No. Download WinISD to see how this works. It's the box/port that establishes the tuning frequency, not the driver(s).

You manipulate the box tuning to make the driver perform in a desired manner....
