[quote user="be"] "another big selling point to me was the 505 being a low resonance compression driver.. there just aren't many drivers with a resonance in the 80 to 100 Hz range like this driver... I have just begun my playing, but am already quite...

[quote user="ulf"] If you have no experience of HornResp I suggest that you download a copy and try it out. It is a very neat software that is useful when designing horn speakers. You can easily make simulations and get a decent result concerning fre...

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="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

[quote user="haralanov"] Take a look at the video: [/quote]I am not sure why you keep bringing the Vengerov’s video again and again. It is quite banal things and those infomercials of Vengerov educating in front of camera the sentimental girls ho...

[quote user="haralanov"] Your response is a very good illustration of how you redirect attention away from the actual discussing subject and point it to a completely different direction that has absolutely no relation to that subject. You asked me wh...

[quote user="Joe Roberts"] Interesting concept but let me point out a few considerations.
The diffusor does performs a mild "equalization" function if you want to call it that but it is also an aid to dispersion. It is light "EQ"...3dB might be abou...

[quote user="tuga"]If you have a midrange driver you can try that for yourself.[/quote]In this case the lack of "full-range" audio is so glaring it overwhelms any advantage of the point source, I think.
[quote user="tuga"]BTW, do you consider elec...

Ok, I found my RTA cable and did some very basic measurements of what Macondo does in the room. The results were in the direction that I anticipated but worth in amplitude. My right bass channel that that sited right next to the equipment bay has no ...
|
|
Since my new tweeter will be arriving in a month or so I am slowing completing the ideas of finalizing the frame of my Macondo. Whoever dealt with 4-ways horn-lodes know that framing of this thing is quite tough. It should be functional and none-abus...

Part 2 – Description and explanation
Anyone who have ears and a rudimental mind to understand what ears register, and anyone among them who played with MF channels driven by SET, know that subject of SET loading is imperative.
Let take for...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

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...

[quote user="jessie.dazzle"]I really appreciate the result of the 180Hz horn with the S2... Particularly in terms of "texture". It is responsible for such an important range... [/quote]
Well, if you appreciate the lower knee of the S2 driver then wa...

Cessaro ALPHA:
TAD TD-4001 2" driver on tractrix horn with 56cm bell (approximately 250Hz). TAD claims response from 600-20KHz. Given that the midbass is essentially a direct radiator (theref...

[quote user="op.9"] I agree, there is probably very little to learn luthiers that is directly applicable. However, I've always been interested in the similarities between good speaker cones and thin lacquerd spruce. Sort of a crispy pingy sound even ...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...

+++ Tannoy-style ("Laid Back"): dampen the distortion relative to the music; these listeners can tolerate less distortion, but also need less of the musical signal to be satisfied.I wish I would agree was that what I'm hearing from Dunnoy I might ful...

This is a very important question as since very beginning of the projects it was questionable if I would be able to get away with the back/top firing position of my midbass horn. So, as now, when the midbass horn project is over and horns fully i...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

[quote user="Romy the Cat"]
...this interesting point has no practical answer. First of all in the case of Rakesh horn what N-Set proposed is not necessary. Those 115Hz Hasqiun-style horns that Rakesh emulates are well dumped with own mass and own ...

[quote user="jessie.dazzle"]Rakesh,Two things I see that may or may not turn out to be an issue:1) The relatively narrow stance of the front wheels; depending on how heavily you load the top of the frame, stability could be a bit on the limit when mo...

[quote user="Joe Roberts"]The Manger is very different from Lowthers and other paper fullranges. It is very balanced and not peaky at all. Lowthers are lots of fun to experiment with but it seems the Manger is less idiosyncratic sonically, although i...

I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...

I am NOT talking about single wideband drivers or any back loaded type horns. I am talking about properly made front loaded horns.
For example, the Danley Synergy horns, that use single horn with multiple drivers to cover a wide band...

of dB not octaves! Look for a threated:

Oh, rowuk, you have no idea how much I agree. To me passive theaters very much like ports and I hated anything which stay even remotely close to it. However, this time the entire Remedios project is is very different s s is built not based upon knowl...

Last week I spent a few hours at the scene of NY’s Stereophile Show – HE 2004: a half-day on Thursday and 2 hours on Friday. As many other audio-shows it had many semi-ugly colorations, however as any audio shows this zoo trip brought it’s own “inter...

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]
I do not think I called you with names...
