What to do with a JBL Le8T ?

Build RCA-fan's backloaded horn cabinet, sounded insane with the LE-8TH in it. With 25w and corner-located it would pound me all the way to the other end of the house. Do you have two of them? Stereo, my gawd.
RCA-fan's gallery has the plans and some photos....

The main thing is to listen to it...
The Le-8 has one of the best midranges in a cone speaker... I think it is the extension of the JBL D-208 in heritage...
It likes to have a big front baffle, btw... for flattest lower mid response.
Personally, I'd not try to use them for low bass, nor take them too high... but I would use them for a "3-way" system based on a very wide range "mid" taking it down to ~50-60Hz. and go up to 3-5kHz., supporting that on either end with a good sub and a high quality high efficiency tweeter on top....

I agree with bear. The LE-8T's I had were not up to todays standards for bass so you need a woofer. I had mine crossed over a little higher (8k I think) because the aluminum dust cap seemed to carry a lot of the highs and I didn't have a problem with beaming. All in all a very nice driver.
The surrounds went and I couldn't find a proper replacement and a recone up here in Canada was approximately $350.00 per driver. So I sent them south and haven't heard from the guy since. (Stephen Jove)

I'll pile on agreement with the assisted-widerange concept. The best results with this type of driver seem to come between about 80Hz and 8kHz. 99% of criticisms arise from trying to exceed that envelope. Within their limits, they're extremely nice.
I've got a pair of OBs with 20" bass drivers on the bottom and RS pod tweeters on the top. I've tried all sorts of widebands between (see pic below). Currently enjoying a pair of Stephens FR80's--very similar to LE-8T's.

Hi,
The woofers are from steelsound.com. They're real sleepers—alotta sound for not alotta money. They're run OB and have solid performance down to ~30Hz. The sides you see are just ears projecting back to improve low response a bit and support the rest of the baffle.
I was running them off the amps you see (Parts Express cheapos with a useful 6dB 30Hz bass boost and variable lowpass crossover) with very good results. I'm now experimenting with triamping via a DCX2496 and two Panasonic XR25's, but I may return to the old setup for simplicity's sake.

I find them very satisfying.
They're the simple product of the best bit of audio philosophy I've every heard: worship the midrange.
When you've got a nice, dynamic wideband covering the entire vocal range plus the first harmonic, comfortably nestled between a solid, room-friendly bass module crossed over quite low and a smooth supertweeter crossed over quite high, it's hard to go wrong.
So that's my advice for the LE-8T's...

Good advice for any fullrange driver, IMHO.Bill F. said:I find them very satisfying.
