Is the tweeter the same as the ESS Heil Driver ? If so , the low end can be extended to as low as 1.6 K Hz and it 's response is very smooth and open !

Not really, it is not an air motion transformer type, but I feel that must be a family branch of the Heil (The working principles are so similar).  Heil is nicer to me, just the magnet is 13LB, one of the best I have experienced.  Ess flagship product, Heil Limited, it cross-over at 800hz (12db/octave slope if my memory is working right),meaning the mid/hi range sounds as clear as light, with a 12 in woofer and 12 in passive radiator and almost identical to the AMT Monitors.  I would love to own a pair of ESS if they don't have such shitty lows...LOL

Elac jet is not equal to ESS Heil.  ESS = ElectroStatic Sound
The jet is not Electrostatic tweeter

好音响要有人识欣赏

I knew it ! It is a ribbon tweeter, like the Deeca.  Based on the concept of Heil design. (Refer to my previous posts)

"ELAC's signature JET tweeter is their advanced development of Dr. Heil's Air Motion Transformer, a transducer without conventional voice coil assembly. A heavily folded Kapton foil membrane sports a chemically bonded aluminum layer etched into which is a quasi voice coil. 0.84mm wide, this driver operates like an accordion, squeezing air out of its folds at high velocities, albeit with the mechanical motion -- and this is the trick -- not in the direction of the listener but crosswise. This concept displaces a lot of air with minimal effort to explain the general claims for high dynamics and good efficiency with AMTs."

Well, only the top line Heil thought, but it shows it how good it is. It is no Tympani nor Duo Quad ESL 57, but for the money is excellent value.  (Heil Driver is also sold separately for $400 USD each, can't beat that!) Great for Bi-Amp with a good active cross-over.

I have a friend using it as the tweeter:
Tweeter:AMT 1 driven by Audionics CC2,Cross over 5K
Mid-range:Rogers LS3/5A, low cross over cut at 100 Hz,driven by Threshold 100 class A
Subwoofer: Hartley 24 in. custom made cabinets, driven by Kenwood 09,below 100 Hz with a Dalhquist low-pass filter
Cross over : Audio Research EC 3 ( 6dB per octave )
The volume of the drivers could be adjusted by the EC 3.
The sound was nearly as good as the HQD system.
The sound of the organ in Saint-Sean's Organ symphony was shaking the windows ! Subsonic !
He has now changed his system because it was so space occupying.

AMT 1 cross over 5k, kinda waste..but 5k is a good cross-over freq.
Roger LS3/5A is no Duo Quad panels, (not even close to req pair of quads) such mid-range wouldn't even be better than Kef or my old little gale's mid driver, hehe.  very nice small speakers though, only personal opinion.  
Harley 24 in woofer, that nice
cross-over at 100hz and 5k? 4.5in Rogers Mid from 100hz to 5khz? Are you missing something? (Electrostatic panel plus ribbon tweeter is better option)
I know Kendwood mono blocks and Threshold Amps inside out after years of listening to them, they NO Mark Levenson ML2 Amps, but they are nice amps, too. Prefer L07mII better (still have a pair in storage room), Thershold 400A 100watt amp is not a true class amp, they call it Cascaded Class A, I always made joke on them with my friend using my Audio Research Amp hehe (saying mine is not true class A lol..).  O, Audionics of Oregon, geez have not heard that in years, hehe.
It is a nice system, no doubt, such max and match do take time and they No Mark Levenson's HQD though.
Guess your friend has been messing with Hi Fi for over 30 years, just like me, since 1977.  lol...
