OB fullrange driver to use with JBL LE14A

vaughn · 8th June 2009, 09:21 PM

I recently built a pair of Econowave speakers as described over on Audiokarma and have a couple of questions...

I would like to try something like MJK's Goldwood OB with a couple of exceptions; I would like to use the current JBL low end and marry to it a nice quality wideband driver of similar efficiency on an open baffle for the top end. I want to keep it as simple as possible and I would like to decrease the current low pass crossover from 900hz to something even lower, maybe around 200. Ideally I would use the full range driver with no crossover and just let the low end roll off naturally.

I need suggestions for a good quality fullrange driver with a sensitivity around 93db that would be suitable for OB use.

Suggestions?

Evaluating my own curves in OB averaging from 200 Hz to
1 Khz in an OB (This where I think it counts) I get the
following candidates, all within about a decibel:

Audio Nirvana AN6 super

Fostex FF165K

Fostex FF225K

L Cao 8 inch with ceramic magnet

Lowther C45

Lowther PM6A (16 ohm)

Feastrex D9nf

Thanks, that it is about as complete and prompt and answer as I could hope for!

I'll look into each of those and see which wins the price war...

Keep in mind that these are all 1 meter response. I am
only assuming that the JBL's spec will match up to this.
