[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...

This is the text that John posted a few years back at Triode Mafia. John allowed me to post it here warning that he have learned more about tapped horn since then and hat his opinion might have changed since then. -- *****************************...

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.

Above I was discussing the new integration process I used to mate the tapped horns with the rest of the system. Below is a graphic to help explain the listening arc. I just moved the tapped horns along an equal-distant arc until the phasing of th...

Jessie’s comments about my idea to position midbass straight horns from basement, upper- firing and his warning that the horn will get converted into a giant garbage can made me to think. I did not think about it but it is a reasonable concern. Hypo...

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...

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...

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...

Battling horn criticism is the very same thing that battling audio superficiality, lack of serious criteria about audio and ignorance aboutthe phisics and geometry involved. The really annoying thing is that audioworld was ,in his early developement...

This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensi...

As we are looking for our new home I am slowly simmering in
my mind the ideas about new midbass horns. It is not that I am short for ideas
but I am not sure that I will take my family on a bumpy and costly ride to build
new horns. One way or anoth...

It is so funny. As Kitty and I are looking for different
houses we look at different listening rooms and we have different ways to think
about room sizes. She think about space for her piano and size of oriental ran
she would drop on the floor. Wh...

Wow, Josh, that's a whole lot of writing! Truth be told, I did not read it all, but I see (and hear) the back-horn. Hard to believe after all your experience that there is still "more" out there, but maybe you will also find time to read extensively...

This new speakers from DeVore look interesting, though subwoofer could be better. I wish they were sealed box, but this is what it is. Unfortunately there is no chance for me to listen to them, but I'm willing to hear your idea or anyone who had chan...
