Look to "next generation" damped laminate 4" diaphragm drivers for a start, maybe.Originally Posted by speakerdave
I'm guessing we'll see an "improved" 2435HPL in the future, as well.
I'm just one day with 2452H-SL so far. A smooth 20 kHz is plenty high enough for me.
Re: the bass - the cabinet appears suitably configured for optional 1-Pi (corner) placement, if desired....
Is that like a ferrite 2450SL?Originally Posted by Zilch
Off topic in DD66000 thread, perhaps, but, nope, neodymium. More like 2451SL, it would seem. Throatless "pancake," presumably "Optimized Aperture," JBL uses them on PT Waveguides in their new high-end Venue Performance series. Follow the link here:Originally Posted by speakerdave

Don't know much about them; "damped laminate" seems to be aquaplas'd titanium. There may be other changes, as well, to warrant the new designation.

In addition to the damped diaphragm, "SL" version has a smaller (3.25") horn mounting bolt circle.

That's what I'm getting on PT-H95, too. They'll make their way onto modified 2352 horns here, ultimately.
They just recently showed up as purchasable on the transducer list at JBL Pro Parts....
Speakerdave, I was at JBL some months ago with Don and Sgt. Schultz and we got to audition the new systems at length. I believe I remember Greg Timbers mentioning that the crossover point to the supertweeter is 20kHz.- that is, the tweeter functions only above 20kHz. Don and I then took trips to the front of the room to plaster our ears against the tweeter. We heard, as Schultz would say, "noTHING."
Allegedly, you hear ultrasonic with your eyes, not your ears.
[I don't think I do, in either case.... ]
All the supertweeters cross at 20k, in the Studio L, K2.Originally Posted by Steve Schell
Everyone knows that the purpose of that supertweeter crossed above 20kHz is to keep the rodents and bats away. JBL pest control.Originally Posted by MJC
I would love to have the chance to see and hear this exercise in art, science, and legacy in person. I'm quite envious of what Don was invited to do. It really must be exhilirating.
I doubt we'll have the chance here though anytime soon. I've been to something like 17 consecutive Winter CES shows, and everytime there was a flagship JBL on display, they've never been connected to a music system....never playing sound. Just sitting looking pretty.
