What is/whas the purpose of the JBL E145 15" driver ?
Is there any replacement?
The frame seems to be really huge if you compare to
an 2225 15" driver. . .

I would love to get my hands on a pair of them to drop in my mains. My 801C is based on it and it is one really nice sounding driver. Vocals are great, fast, effortless and clear as a bell. And bass is well just great. I have on the DTS Hell Freezes Over right now. With Timithy B Schmidts bass and the vocals Don Henley and the rest through the center. Definately worth a listen.

JBL made a point of differentiating between the two applications - sound production and sound reproduction - the former being transducers for electronic instrument cabinets, and the latter being the focus of most on this forum (HiFi speaker components and cabinets).

I too, love the sound of the E-series, and have made sure the guitar player in my band swapped into the E110's (with stunning results... ) for his Fender tube amps, but I have not dropped E-seires (or comparables) into HiFi applications, finding them a bit "brash" for that application.
Others out there have experiences, pro, con?

"Indeed, not!!"
I was talking with a man here in sweden who liked
the e-145 more than the 2235 up to ca 600hz, more
attack he said..
He used it with 2202, 2245 in a custom built high end
model loudspeaker.
Hey Bo
You are right they do diferentiate between the two groups. The E-145 is very special as far as the E group is concerned. It has a underhung coil and is very linear driver. Just like the 150C K-145 where you can trace its lineage or the LE-15A or Altec 604. This makes it well suited for sound reproduction/home hi-fi. It also has a very powerful motor on a very light cone so it is really fast and clear. Take a look here

You should really take a look at the whole documnet. Lots of good stuff there.

That was a great page indeed !!
Yea, Rob, I know. The discussion of the different surround compliances and designs I found very interesting, too. I recalled having read this page (p6) when Giskard was recently harping on the importance of surround integrity (and uniformity) while collecting meaningful measuring of cabinet tuning.
A very critical element in transducers performance.

"when Giskard was recently harping on"
harp harp harp harp harp
"dwell on" is more along the lines of what I was thinking.
But maybe "emphasized" is more appropriate...
Either way, PLEASE KEEP IT UP!

Hi Rob
It's so true, so many good speakers, so little real space & time to enjoy them all. I too would like a pair , just to check out the speed/quickness thing . Would also like a pair of K145(s) because it has a heavier cone / quite similar in the cone weight to the 2220/130A but still with that huge motor. Really do need a "Noahs' Ark" of this stuff to arrive at the perfect "personalized" system.I would love to get my hands on a pair of them to drop in my mains. Robh

Well shoot, I was going to go over the TS parameters in a post but, true to form, the JBL published numbers for the E145 are all jacked up.

Well????
Rob you can't stop now. Do you know what the correct values are??
Hello Earl
Yeah you sure are right about that! I don't have space for one more driver unless of couse I see another sweet E-Bay deal!! Never enough time.

Hi RobG
You and I went through this a couple of forums ago. What TS numbers were/are wrong. I remember you reporting that JBL said to measure it yourself,,, etc. The numbers I use seem to give the appropriate curves for this class of speaker. Here's a pdf of a 2 cu' , 50 Hz tuning I did quite a while ago ( ignore the date stamp ) . How does this curve compare to what you see with your tuning-prediction software?

Ive had these magnet assblys reconed with 2235H kits. The cone traveled more on the 145 magnet then the 2235h mag assbly. I bet the 145 wiil sound great for upper bass and have higher power cabable but will loose below say 40 hz. In my application the 2235H was smoother. woulnt ming hearing a stock pair of E145 good luck
