midbass

[Tom Loizeaux]

I believe the JBL 2118 is the current 8" driver and it gets high marks from many users.
A popular 3-way system uses a 2235H, 2118H and 2404H, with the 2118H handling the mids.

Just want to say that the JBL LE10A didn't work as for midrange driver.It work fine in enclosure as bass-midrange up to 2000Hz with a smooth tweeter such as LE 20 but sound poor with 2420 midrange ,2405 tweeter and 136a bass.In the bandwith of 300-1200hz ,the LE10A can't be compared to a D208 or D216.These 2 full range drivers are just clearer and have more "Dynamic"(Don't know the english world for velocity vs time)than any others that I tried.

But the LE10 is a good driver for small enclosure and I use a pair with PR10 and LE20 in 2.5 Cubic feet enclosure for my bed room at low level late at night.

Ahhh... Nearly the legendary Lancer 77. Nice!

Hi Jakob

I'm quite late to this midrange chat party,,,( I've been away & I need a RipVanWinkle smilie here ) but,,, what other components are you intending to use in your 4-way system ? From all the enthusiastic testamonials for the 4343/4/5 type systems abounding on this forum - you should be able to find a common denominator from the published mid-range specs . This suggests the 2122h family to me ( if you can find a pair ) .

I have 2012, 2123 & le10a/h/h-1, ten inchers and would/do use them in different applications,,, all with different system voicings.

For instance ; I just love the overall balance of sonic attributes from the le10. It is low efficiency but its aquaplas damped cone with its' high compliance surround and long coil does generate a nice balance of well damped mid that does punch - when there are many ( 300 ) SS watts directly driving it. It may lack "snap" - in my lexicon of terms. I could understand the comment of the le10 sounding too subdued/slow once mid content has been filtered into it through 18 gauge ( high DCR ) inductors. I've done that and thought it a bit "tame". I nixxed the lowpass coil and all was happy again. I like this transducer best when utilized with other well damped " maybe - aquaplased" components (ie; le14 and a 2450sl diaphragmed compression driver or my favourite - the well damped, Altec 288-8K ) . I prefer this combo in smaller rooms .

The 2123 does have more "snap" than the le10 ( but I feel the le10 "out-punches" the 2123, in my own vernacular ) The 2123 needs to be mated ( or voiced ) with components that compliment this attribute. The 2012 is even a bit further down that speed road, IME. It has a published response curve that suggests a little more than a simple "plug & play" component for the DIY designer . Both of these tens are nice midrange devices . I make a small 2-way enclosure that uses the 2123h with a 2426h on a small CD style horn (RCF) that can be extremely HiFi ( with bass below it ) when all is properly tweaked. The 2012 has better midbass ( in the 150 to 300 hz area ) than the 2123 IME with its' more massive magnet and deep-gapped, long voice-coil .

The 2122h ( which I've never heard ) ought to exhibit, yet another balance/trade-off of resolution/speed/snap/punch,,, this observation is just based on its published specs. JBL has classified it as "obsolete" and made it hard to get . One ( maybe overlooked ) advantage is it has similar efficiency to that ever popular DIY, 2235 woofer. This helps simplify the passive crossover design process if that's the route you're taking.

It never ends, does it?
I mean the constant flow of interesting aspects and information You get here on this forum?! Thank U!

Earl K: The rest of my system will consist of: 2405, 2416, midbass (midrange to You DavidF ) and for the lower end my K25 basshorns. If the basshorns does'nt perform as I want them to with their new drivers, I'll replace them with something like two 2235's /side or maybe... ...well give me a tip!!!

For the mid, and for now, I can choose between: 2110H, 2118H, 2123H and the LE10A. Still haven't decided yet...

Hi Jakob

I got you beat...i was searching for freq response graphs for an E140 and came across this.

We built 4 small stage monitors using 2118's, mainly used for smaller gigs. Anyone who has used them has loved them. They have an MG tweeter to reproduce top end. These cabinets typically are used as monitors without any eq on them at all. Definately worth looking at for mid reproduction (you probably found something already though, after all, you've had almost 5 years! )

Well there ya go bragging . I guess I'd brag too if I lived where you are, it's beautiful country you have up there .

- That's not surprising, Clair Bros ( and Audio Analysts ) used to have small front fills based on this very speaker . The 2118 really is a nice performer in the midrange . It's no real wonder that a slightly modified variant was used in the 250ti series of HiFi enclosures ( "slightly modified" meaning / the addition of aquaplas to the cone ) .
- The 2407 or 2408 should work quite well in your micro monitor if you want to keep it all JBL ( and if you like or need, the smooth sound of a mylar type diaphragm ) .

-BTW, the 2119 appears to be a modernized version ( meaning, in JBL Pro parlance , higher power handling which is quite likely due to a slightly thicker top-plate and a slightly wider gap when compared to than the original ) .
- I don't know this to be fact ( since I don't have any examples here and / no-one on the forum has bothered to research info about the newer version ) . It ( my conjecture ) just makes historical sense .
