What to do with an E140

[pangea]

A friend of mine has a single E140 and I would like to help him make use of it somehow at home.

So, I'm asking if anyone could suggest what to do with it.

Does your friend play electric bass? -grumpy

Probably the simplest route would be to build a sub woofer cube with a 15" passive radiator on the opposite side.

Other than that...use grumpy's post.

No, he doesn't play guitar. He found it in a container. It had been thrown away because the dust cap had been dented, go figure!

How deep would the sub be able to go, if used with a passive radiator on opposite side?
I think he's got another cheapo 15" lying around, which might do for now.
Would a 2 to 2.5 cu ft box be enogh?

Ah, perhaps then have it reconed as an (almost) 2235 and build a real sub... ala B380.

I'm not sure my friend would see the point of replacing a working cone to another that almost looks the same. He doesn't know the first thing about Fs or any of the implications that different T/S values create.

I therefore think it'll have to be done with what he's got.

Maybe use 1" MDF, build a 20" cube. Mass weight the PR to resonate at 30hz or so. Adjust weight as needed to suit sound taste. He'll need to make a simple low pass or drive it with an active x-over and amp.

Part of the fun of that type of project is the nearly no cost involved. The real audio guru's around here will probably laugh at this design....but whatever....it's not for them is it?

Personally, I think it a waste of energy and time. No bass below 50-55 hz, and a short cone travel or Xmax. I never liked them much even for bass guitar, because of the lack of low end...he should sell it and start with something else, even if it is not JBL...just MHO.
