Hey,
does anyone know the internal volume and port dimension (lenght & diameter) ?
Thanks a lot,
Olaf

If no one else responds, happy to measure later tonight.
That would be very kind, thank you in advance!
The internal volume should be 4,5 ft³ according to the JBL literature, but I can´t find anything about the ports
Thanks a lot so far
Olaf, If you missed this thread I post the link here:

Thanks a lot.
External (ignoring corners and rear skids):
19.5x29.5x18.5" (WxHxD)
Internal (noting baffle is inset):
18.0x28.0x14.875"
2118H doghouse (subtract from calc volume):
9x8x6"
port:
6" dia
5.5" depth (rear of duct to front baffle)
all above dimensions to <1/16" accuracy
... so perhaps closer to 4.0ft3
there are at least two braces (one vertical, flat on back, perhaps 2" wide and 1/2" deep
and a smaller cross brace (front to back) that also supports the doghouse. I doubt they
are significant re volume calc ... esp when fiberglass (top/bottom/sides) is figured in.
Thank you so much, you´re a big help!
Looks like a 40hz tuning with a gentle roll of below 100hz...
