Again, none of the pneumatic methods would work as any pneumatic leak air with time and it will be no access to it after the horns are installed and the walls are finished. Not mention that we have no high to play wit. We will be doing the follo...

[quote user="RF at Ona"] Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I su...

We have two models with different upper bass horns, one is indeed a 140hz horn (77 cm diameter) and the original, bigger horn at 110 hz (92 cm diameter) Both tactrix both made from the same materials (MDF) and finished in the same automotive finish.T...

[quote user="Romy the Cat"]The brickish finish does not make me cringe, in fact I do like the idea. I do not feel that it would be some kind of non-truths. There is no truths or non-truths in it. The only a few first feet of the horn will be visi...

You need to decide what length of the horn you can afford. When I mean “afford” I ment the position of the horn in context of the rest of your system. You know the lowest cut off - 40Hz. So, the most suitable for you length and the mouth size will gi...

[quote user="jessie.dazzle"] I have not heard any other systems using Vitavox S2 drivers, but I know it is possible to get the S2 to generate on-axis unpleasentries. In the case of the system I am building, one can happily sit straight in the firing ...

And now, going back to page 2 of this thread; here we pick up with some shots of the upper bass horn and the associated primitive "tooling"Mold without coreMold with core. Before core is put in place, mold is loaded with a thick coat o...

Enduring a quite aggressive schedule to the end of the month to finish the horns, I realize how much work is still ahead. As now both of the horns are built. They are no prepared to be painted yet and second skin is not built. This notion that ¾ laye...

[quote user="guy sergeant"]Is there no way to smooth out the visible steps in the latter part of the horn's expansion or would you prefer not to?[/quote] This is very interesting one. Yes, there is a way to smooth out the visible horizontal steps. Th...

op.9,
to put your comment I perspective it is necessary to know what surface you had on your Lecleach horns before. If you search the site (use world textured or structured) then you would know that I am a vocal opponent of smooth surfaces on horns....

If they paint/anodize the driver in black (instead of this screamy and shiny finish) and to crap the horn with zillion random texture dots then they would be almost my type of people. ...

first post... but I recognize quite a few friends here.. so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet&nb...

As I said I do not truly have any audio Christmas List. If I move I will build my midbass horn but with all honesty if I move and will not go for midbass horn then it will be little difference. With my current understanding of sounds I am very co...

de Charlus, I still do not think that there is such a thing as “ the only a theoretical starting point”. Perhaps you were inspired by Jeffrey’s recommendation that has more experience in it then you. Still, the compression drivers loaded into giv...

Kodomo, what is your ear height when you are sitting in your listening chair? I guess it is less than 120cm. Perhaps when you finish setting up the horns and remove the wheels effectively lowering them you may be in the position of lowering the twee...

Hi,Finally, I have time to build some horn speakers and learn what is it, bought JBL 2440 drivers and before my frame will by finish (next week) and horns will arrive I want to renovate those drivers. My question is:Can I take off that "grainy" topc...

How Wilson sounds:Pressure caused by non-linear bass squeezed through narrow port holes.Shining caused by the papery upper mids of a too high crossed 6.5" midwoofer.Sparkle caused by the metal ringing of a titanium tweeter.What Wilson does:Use st...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

[quote user="jessie.dazzle"]I've been listening for about one week now with the filters set so the hand off from lower-mid to upper-mid happens higher up (upper-mid S2 is high-passed at 4800Hz instead of 3200Hz), meaning the small 400Hz horn is doing...

Speaking about the interesting surface finish. I have seen a
new stimulating idea that I call the Scratched Horn. I do not know how much
practical effect if has but it shall not be bad. Let pretend that it is not a conical
horn with even sides but...

[quote user="JLH"] The appearance of the Macondo horns is out necessity for purity. As you very well know, the pure analytical form of a horn is a circular cross section. The Macondo horns have virtually no areas of compromise. Size, shape, fla...
