Original or copy cones for 2205 ?

[edgewound]

I have a 2205h that was re-coned with a JBL K140 re-cone kit. This speaker is intended to be used with bass guitar (hopefully even a 5-string if possible).

Can anyone suggest what parameters I should use to build a box for it that is as small as possible, please?

Many thanks for any insight you may be able to provide.

Hi Bill,

A five string bass with an E140 will require some creativity on your part, due to the fact that the low B string is 31Hz at concert tuning.

A compact enclosure will need to be sealed and overstuffed to get that kind of low end, or a passive radiator incorporated and tuned to about 30Hz resonance by mass-weighting/loading.

The original cone looked like D140F with a paper dust cap and had FS of 30 Hz.
The K & E 140 have a stiffer surround with a FS of 40Hz to improve power handling.
A 5 cu ft box tuned to 30Hz might do the trick with E140 cone!
Per JBL T&S the E140 has a FS of 32Hz.
Maybe one of our fellow members that has the software will run it on the E140 and give a good place to start.
