I have a plan to DIY the enclosure for driver JBL D140R (to play bass frequency in 2 way speaker system) but I don't know which kind of enclosure is the best. I wonder beween the Onken360l Cabinet or Bass reflex design by JBL for driver Le15A (8 cubic feet 914mm x 610mm x 406mm).
I also want to know the technical data of driver JBL D140R and which JBL's driver similar with D140R.
Thanks in advance!
