Hello,
Well they should use your services at shows Mr Bastor, if one were to read back at the comments from show goers , I have only repeated what was said, they were not my comments, unfortunate you consider comments from show goers "garbage" and missed my tongue in cheek sarcasm at it's highest level , it was really directed at those defending bad analog sound at shows and I'm glad Mr Koh had the testicular fortitude to step up to the plate and not have another static display ..
You have a history of merely repeating what others have said which I have pointed out before thus my "Polly Parrot" remark I made before in reference to you and your posts. Do you have any original thoughts you would like to share with us on any subject or are you too busy with sarcasm and repeating what other people have already said?
Yes,
My apologies to Gary and others, unfortunately some choose to discuss more than just the subject matter at hand with personal retorts ....

The Genesis 2 Junior (someone said - there's nothing "junior" about THAT speaker) is the smallest of my line source loudspeakers. It is just over 6-feet tall, has 12 Genesis ring-ribbon (actually planar magnetic) tweeters as a line-array, and a true line-source for a midrange that is a single 48-inch ribbon (also actually a planar magnetic). Each speaker has two 12-inch woofers handling the bass frequencies - each woofer has an individually servo-controlled bass amplifier. As the woofer is only 2 ohms, each woofer has 1000W on tap.
In a room the size of the Venetian suite, the speakers are virtually "unlimited". One of the most requested albums today was Touch Yello. We played it at Ibiza night club levels, and people who had heard it told their friends who then came in and requested it. Unfortunately, we played it a couple of times too often and too loud and as a result we've already got a warning to keep it down. We don't want CES to shut our power off, and so we won't be demonstrating the "unlimited" quality of Junior any more. Tomorrow, we'll be meek as a mouse

The most frequent complaint about dhow demos-too loud.
Funny I would have guessed 48 inch ribbon line source as tweeter.
The G2jr has a single 48-inch long ribbon
midrange and twelve1-inch ring-radiator ribbon
tweeters on a 1 ½-inch thick solid cast acrylic
non-resonant baffle. In addition, two 12-inch
aluminum woofers plus a 1,000W servocontrolled bass amplifier are built into an
attached bass enclosure.
In the mid-high frequencies, it is a true dipole
line-source. That means that there is minimal
vertical dispersion, and horizontal cancellation in
the plane of the drivers. The result is minimum
floor and ceiling bounce and very much reduced
side-wall reflections, resulting in solidly pin-point
imaging and a wide and spacious soundstage.
Another advantage of a line source over a point
source is that less power is needed to maintain
the same loudness level with greater distance
from the loudspeaker. Conversely, the same
amplifier will sound far more dynamic at any
given seating distance.

Thanks Gary, interesting stuff. I have read (though could not cite a source after all this time) that one reason for breaking up the HF ribbons (or planer magnetic) drivers into smaller sections was to reduce modes in the longer strips as well as make them a little easier to drive. Whatever the reason, I am sure it sounds great!
As a long time owner of a G201/200 (201 for the panels and amp; 200 for the woofer columns) that has, I assume, essentially the same tweeter/midrange combination, and still sounds great - I can only imagine how much better this newer model sounds with better electronics and cabinet construction. I'm curious, Gary, why you guys chose to build the amps into the back of the speaker rather than using external units like in the 2.2?
We only played loud when called for - like when the audience wanted techno chic at night club volumes. Most of the time we are enjoying quietly played music quietly. Even after the techno, I would demo what the owner would play after the lights are off - 20dB lower on the volume control of the Crescendo, and you would hear all details.
I've got to remember to update the website description of the G2jr. We've gone from a single amplifier inside the speaker to two amplifiers and separately controlled servo woofers. In a small room like this, it's very important as I don't want the room modes to control the woofer. The additional servo control on the second woofer makes the G2jr work far, far better in small rooms - which is why I dared to bring it to The Venetian this year.

I had both high-rez music server available for anyone bringing in USB sticks and a Burmester 089 CD player. No one requested digital.
First, for the Junior was a cost issue. I was originally trying to get to a price point (but ultimately failed because I had to add more and more to make it worthy).
Secondly, it makes it extremely difficult for the owner to "break" my coherence between the woofer and the midrange. With the external amp, you can drive it from the preamp, and the difference in group delay between your power amp and the power amp of the woofer is an unknown quantity/quality. By putting the amp inside the speaker, it becomes part of the crossover and I can guarantee coherence between the bass and midrange.
As usual, with technical things, you're right. I've been told that, but you trade off one problem for a different problem. I re-worked the ribbon with the manufacturer to fix the problem of the string mode of the long ribbon as I thought I preferred that to solving the problem of a midrange line-array.

Big Yello's fan here; I have all their CDs (made in Germany), and few on LPs.

Gary, your picture attachment is not showing up.
That's strange, it's been uploaded to WBF. I can see it on Chrome, Explorer and Firefox and also iPad and Android......
---- I use one (and two) of those.
But I can assure you; I see no picture at all!
* This is the only picture attachment from the entire WBF site that I cannot see.
...Or perhaps there is one or two more, but that would be from a very long time ago.
Thanks Gary!
And yeah, I have learned to not comment on the non-technical as I'm usually wrong, at least here, but it doesn't stop me from opening my big mouth (keyboard) anyway...
Would you care to comment on the aluminum woofer cones vs. other materials? Or link to where you have discussed before?
p.s. Tonight I cannot see the picture; I am on Comcast if that matters. Seems odd only some of us can see...
