Hi everyone,
I am currently using JBL E145 drivers in the (much maligned) 4560 cabinet, and while I am pretty happy with it (I use it from ~100 - ~800 HZ) I have always thought that I'd like to try an Onken enclosure for it.
Using the onken calculator at mh-audio.nl, and the JBL published specs for this driver, I end up with the following:
box cutoff frequency (-3dB): 40.41Hz
port length (corrected): 27.76cm
port width: 4cm
Vb: 319.96L
Vb total: 342.17L
SPL: 97.37dB
So, a couple questions:
1) Do these #''s sound correct?
2) How do I arrive at proper box dimensions?
3) Are there generalized plans for building an onken enclosure anywhere?
4) Am I heading down the wrong path?
thanks for any thoughts and help you can give me.
Regards,
Byron
