Hi everybody, after reading RomytheCat's Macondo Setup I am very impressed ( phantastic music room ...) . Presently I have no working horns ( they are boxed), just questions.

Give yourself time and let your unconscious work on it; you might have overlooked a cause originating in the electronics.

Ronnie,
Very nice, though I do not know where you would like me to move the thread. (It looks like it’s OK where it is). There are some comments that I might to pass.
You decided to go for a large MF driver. This is fine if you like it but I ...

I got today from my machinist the complete MiniMe enclosure, he did a good job. It looks so simple but it was reportedly pain in ass to do it, not to mention that it turned out to be much more expensive then I originally expected. The good part...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...

Paul,
I have been working with trumpets since 1966 and horn speakers since 1975. I have built both and am pretty familiar with what they are, the similarities and the differences.If I had to pick THE major sin when thinking about all of the horns th...

Well, it happened with me, one of my HH of my DAW, or as they call it “music server”, went down. It does not recognize by BIOS anymore, suck, it would be costly to recover data from there. Partially the most important f...

Last couple month when I rebooted my DAW it has difficult time to start up; it looks like motherboard is going and bias sometime during boot does not see hardware. Usually with 30 min and 10-60 automatic recursive attempts the machine boots and t...

Do proper horns "suffer" from K2? Do you not think that the back chamber loading is part of the engineered concept? Are you sure that reflections from the room that travel through the horn to the diaphragm would not cause more trouble? How can yo...

Here is an article by Leonard Norwitz that I think some of you might find motivating. I do not know Mr. Norwitz but it sounds like dinked too mach Qvortrup’s coca-cola. Anyhow, although I do not agree with some (sometimes many) of the Mr. Norwitz’s c...

I have been observing these phenomena for years and I have no explanation for it. Not that I requires any explaining, BTW…
Pretend that you have a stereo installation where right and left channels produce absolutely symmetrical acoustic output. A sl...

[quote user="jp"] I assume a simple hole sealed with silicone would not suffice given the amount of pressure build up in the rear chamber? [/quote]
The pressure that builds up in right rear chamber is truly enormous.

Pierre, yes, I understand it. It kind or irrelevant what they destined for and yes, in domestic applications in context of low power we can use it lower. What I am saying is that as we do use it at extreme low range we deal with slightly overdamped d...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

[quote user="tuga"]I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter... [/quote]

Yes, I was not able to decipher right the way why they did it. My initial feeling was that they made PROPER horn and use a PROPER driver and then, because the approximation of cut off to horn rate they had audacity to cut off the response on the horn...

With Ming permission I post a fragment of his emails where he describes his midbass horn. It appears that he uses cone-drivers with ltooooooo ow Fz in non-compression application with no back chamber. Now it is obvious where he is losing his midbass ...

[quote user="MINGSU"] The SG146LD4 driver can play down to 20Hz but we choose to crossover the horn at 70Hz only due to the space limitation of my listening room. [/quote]

Angelo,
I care less about the “commercially available” objectives, honestly it is too boring.
