I visitor of my site shat me an email informing that that above depicted horn installation by Marc Henri and Andre Klein was made French Musique-Concrete company. I do not know a lot about those people, beside that they hand around Jean Michel Le Clé...

The La Horns of cause out of picture in my case as there are very narrow requirements in my channels that do not fit what La Horns offer, even though I do plan to use the negative opening from 1-3 sides and to have a transition to flat terminatio...

I ran today some numbers for the triangle horns. In the best case scenario I hope my attic would allow me to make two triangular horns 4 by 6 feet. I did some very preliminary math and concluded that 4X6 triangle will allow me to do what I want. Take...

Painting the horn in my way the old joke come me. Question: how a woman can detect that she is fat? Answer: when she laying in a beach in her swimming suite the people from Greenpeace are trying to push her back to the water. That was pretty much ho...

[quote user="jessie.dazzle"]It is interesting to note that the evaluation tool shows lines radiating perpendicular to the curve at any given point, just as the sound wave is supposed to be oriented as it progresses along the horns length. [/quot...

Hm, Yes, I kind of forgot the idea of multiple compression drivers blowing into the same throat. I never was too warm to it but I do admit that it would minimize the length of the horn. For sure the right solution would be to make compression driver ...

Hi Mats,I am not using 4 on each side. I will be using two on each side. Until now I always liked sealed enclosures. However Tad drivers are more suited to ported configurations. If you do not push them to go too low and have a reasonable fs point, t...

[quote user="decoud"]Regarding centering: how about making the bolt holes on the ring oversize relative the bolt diameter so that there is some play in the position until the nuts are tightened? Obviously, one would have to have oversize spacers too....

Hi Romy,Got my new Le Cleach tractrix horns (320hz) for the Vitavox S2's. I'm x-ing over at 600hz with 2nd order 12db/Octave which I know is barbaric for you but it is all I have for the moment. With the new horns the S2s are puttin...

Personal, I do not use WE555 and I do not (would not) use the WE555-type horns. Hypothetically if one would go for 4-way system with WE555-like driver in upperbass then it is valid solution, not something that I appreciate but valid. The WE555 is ve...

"I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver." Is this also why you use tractrix curve for expansion? To shorte...

Hi RomyWe build horns anyway some one would like , i have been making the horns that are in the pic for me + the drivers that it use the drivers are a mid bass driver are a6" alum field coil driver i like the sound of field coil magnets +...

Hi Romy. Interesting point as i had similar perception along my recent I ran an 8inch driver with fronthorn. Then just got my hands on a pair of RFT L-3701 (or 3702). http://tempuri.org/tempuri.htmlA fabulous driver with exactly those parameters. T...

Very good point - I will direct Martin's attention to this. Visually, it looks like he did an excellent job on the 340 Hz horns, and the 160Hz horns will be rolled off at 1k anyway but nonetheless, will see what he reckons. Actually, no need - I just...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

[quote user="be"]I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, ...

The first two prototypes is actually one build, the only difference being the volume/area of the chamber. (Perhaps I could have chosen more proper words in describing this part of the horn. By 'volume/area chamber', I'm specifically refer...

I have received some questions and criticism about tapped horns. In order to spread a better understand of tapped horns, I’ll restate the questions and try to answer them.
1.) The mouth of the tapped horn is too small to be useful.
Answer: ...

John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...

i dont think its necessary to use that much expensive fabric. i will use only 1 layer of a nice looking fabric on the inside of the horn, then a cheap heavier layer, then foam.maybe i´m wrong, but as far as i see it, the whole thing has to be stiff o...

"Meant to be?"
With 100.5 dB efficiency in quarter space I plan to use a dedicated tube amp. Yes, some people use high powered amps to see how loud they can get Def Leppard, but I don't see any reason to. And some tapped horns...

[quote user="Kcct82"] Hey guys, I bought the Goto 505TT with S150 horn brand new over 2 years ago. Guess what? I'd still be in sonic shit if I followed the 200-1000hz "recommendation". The 505TT does not perform well below 400hz and when I final...

[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”...

[quote user="Ronnie"] I was under the impression that you did not at all electrically roll off the upper bass, and that the small throat would do all the (kinky) low passing. [/quote]
Nope I did roll of the upper bass channel as my driver goes all t...

From the perspective of pumping of atmospheric pressure the ALE bass drivers might be more capable transducers. It or might not be so as well. To get 40Hz at 110dB in 5” it would take some excursion. I am sorry but you can’t bend the law o...
