Here are some real world measurements made at the 2007 NYC sub shoot out. The distortion numbers and characteristics should help us understand the difference between tapped horn distortion and conventional front loaded horn distortion.
The fir...

[quote user="jessie.dazzle"]Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
Interesting, the phase plug-lik...

RobertAren't those meant to be driven by 250W SS amps ? Did you chose driver for your midbass already ? I thought that for this range 8" Lowther DX series with its 50Hz Fs and its "lean" sound could compliment your GOTO drivers (16 Ohm version has 3m...

Your experiments bring to mind the excellent results Jeffrey had with his half horns:http://www.goodsoundclub.com/GetPost.aspx?PostID=7467&Phrase=VSACIt is also good to hear that you have an "assistant" Jessie.Very good indeed....

The current suggestion from GOTO is to crossover at 200Hz with S150 horn. Of course, you can crossover higher but what are you going to use to cover 220Hz down? If you choose to use the bass horn, you do want to keep it crossover low.&nbs...
|
|
So, you use DCX 2496 for deals but not for crossovering and your crossovers are still on analog domain, right? Romy, I do everything in the digital domain so I use DCX 2496 as my crossover as well (but analog SS pro amps). I know you're no big fan of...

I've been doing a lot of research on how a properly designed horn works
(from initial Western Electric designs to present day efforts) in order
to get a real grasp of what will and will not work. I've read and
saved hundreds of papers and de...

Hi, any photos or progress reports on your 60hz horn. If you wouldn't mind exchanging an e-mail or two I could use some help with design of rectangular horn for my Altec 515s??Thanks,R Weissmanronyweissman@hotmail.comLyon, France...

We in New England generally and in Boston in particularly are not spoiled with ingesting insulations that use horn-loading. I do not thing we in Boston have any industry dealers that have electronics that might work with high sensitivit...

hi rony!sorry for the late reply, my job....i did not start to build the horn, working on a phono stage for a friend. will start to build the 60hz horn in about 2 months. all calculations are done, should be no problem. will be made of layers of plyw...

[quote user="Vasyachkin"]the horn looks suspicious.[/quote]
my issue with it, though, is not the discontinuity in the curvature but rather overall dimensions.
it looks too wide to be a slot. this is a product that is supposed to work at 20+ kh...

its easy to calculate with hornresponse, it can calculate the horn with exponential flare on all sides or with 2 flat sides or with "uniform flare on all sides. you can choose width-height of throat and mouth. if you wish, i can mail you the modified...

Romy's quotes in blue :"...Discussing the Jessie project we multiple times mention the idea of the large midbass horn hanging above MF section... The rational was to have it positionally contra-react the output of the upperbass horn... But do we au...

Someone stopped me at the Alexis Park and told me: “Romy, there is a new Israeli guy in town with his amassing horn. He has a room at the St. Tropes and you should go”. I was almost offended! There was a new horn guy and I never insulted him?!!...

Hello all (from Thailand)!I found this very intersting horn society here by accident and would like to show and share my first experience with horn speakers system.It's consist of 4 way system .[IMG]http://i245.photobucket.com/albums/gg69/krairerk/hi...

Yes, when I move the drivers or for that matter if I move my listening position, I realign.What I hear and measure about the drivers relative distances to each other is this. When I first set up the drivers, one horn ended and the next one started, t...

Sorry to steer away from Harley, but have you Horn guys ever tried different flare terminations? That is, the boundary condition where the mouth and room meet. I once saw some interesting stuff done on large radio antennas that improved g...

You have identified the tricky parts -the transistion between the front and back horn as well as the throat of the front tractrix horn. A one to one throat with the front horn works best with my coaxials and a short 1.25" straight 'ring' ...

“All speakers are equal but some of the speakers are more equal then others”
The more I exposed to the different loudspeakers, the more I’m learning that the horn-loaded loudspeakers are the most interesting creatures. Nope, not because they might o...

[quote user="Romy the Cat"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...

Looking at the variety of exponential, parabolic, conical, tractrix, hyperbolic and whatever ales horn profiles out there I was thinking that we probably incorrectly approach the entire subject of horn profile analyses.
We listen the horns and we fe...

Hi
[quote user="Romy the Cat"]
Dose it means that the “ultimate horn profile” would be a profile that would be a DIRECT AND FLAWLESS CONTINUATION of the GIVEN SPECIFIC DRIVER?

Actually you can make a new driver throat to m...

Yes, the similarity between the horn system and the Baba-Jaga hut on fowl's legs is uncanny. The system might be only loosely based on text book principles, but did you notice the use of cotton isolated wire connecting the speaker syst...

Even though you asked Romy, let me add my informaton. B&C makes very good drivers, but they will run you more than $1000.
Good luck with the frequency response in your new experiment, though I have no doubt you will get great dynamics.

Hi
With the Le Cléac'h horn spreadsheet you can design allmost any kind of horn you want. Short and wide, or long and narrow, or anything in between.
cheers ;)...

Hi
I am not using Le Cléac'h flares myself.
But his aproach to designing horns is interesting, I think.
I did make a Le Cléac'h horn a couple of years ago,
just for testing. It sounded very good.
cheers ;)...

Hi
Some loose thoughts.....
A system where each amp-driver-horn-room interface are designed to work together as a unit in their respective frequency bandpass...
They each have to be optimized to work in their respective bandpass,
