HI Mark, all
Yeah, the pattern control is pretty amazing when the horn mouth gets to be four or five feet tall and it acts like it has one driver over a the entire band.
I guess the breakthrough in these compared to the other smaller Synergy horns is finding a way to combine more than one compression driver into the horn system, the mids and lows are easy but when the wavelength gets to be smaller than the driver, well, another strategy is needed.
The solution for that, sort of a lens / combiner on the JH-90 / J1 took about four months to figure out, the rest of that was easy except for the low end, that was another issue as the goal was to not need a sub.
With an lf output of about 3kw acoustic, the first version could literally shake itself apart.
The switch to one inch Birch and a boat load of bracing raised the weight to a level I wasn't happy with but it is those first J1 stadium installations last year that lead to a bunch more this year.
It has been cool seeing these big installations but a number of times I had wished you and Jeff were along to hear them as in Mark should hear this. I was sitting at the farthest seats at BYU listening to the system playing CD's and the only thing going through my head was that they could play action movies here for a large crowd. That system sounded great at 102dBA slow at 750 feet (they had 4 J1's and 6 TH812's under restraint due to the seats directly under them..
Anyway, the J2 which I am still fiddling with has 42 drivers and is the same size but much more powerful than the J1 except for the low end and the J3, the box in the demo is a little stronger than the J1 except for the extended low cutoff, has 22 drivers, is smaller and is array able.
The neat part is you can sit a few feet away in front of any of these as a stereo and they sound and image great too, no minimum distance etc because there is in effect only one acoustic source.
The fun part is that these sound so much different and work so much better than the normal stuff that when you get a stadium owner or athletic director that is unhappy enough with the sound to get involved, they couldn't care less how new the system is, what speaker company the installer is in bed with or what company the solution comes from as long as it really works.
Check out the facebook page at some of the install's this summer (our web page is way behind, the new one isn't done yet).http://www.facebook.com/DanleySoundLabs?ref=ts
In the demo at Penn state below, the large California line arrays (two years old) sound so bad that a demo of three arrayed sources won the job to design a new system (a J2 forward, J1 right and left). In the video, they are the little black glob under the scoreboard.http://www.facebook.com/photo.php?v=...type=2&theaterhttp://www.fohonline.com/index.php?o...=5658&Itemid=1
Anyway, this is getting fun now, eventually someone will figure out you can show movies to a huge group of people now haha.
Hey, say Hi to Jeff too.
Merry Christmas all
Yeah, a Jericho alarm clock, I could imagine a whole range of practical jokes, such as using it to wake your neighbors with sounds of a helicopter or plane crash, maybe the attack of the totally enormous frogs? It would be easy to hide one or several of something with this much throw for humor purposes.
