Hello Macman,Nice horns, I like that you finished everything properly! I am getting tired of seeing piles of horns.I think the ringing you are getting from your midbass horn is that the throat reactance is not balanced. How did you calculate the ba...

I would like to thank you for taking the time to give me a very satisfying answer and explain in detail your views on the whole subject and give a little more insight in to how you do things. Yes I suppose I really knew all along it was coming and w...

[quote user="haralanov"] Yes, you are right. Power – you have almost unlimited power. Dynamics – you have as much dynamics as you want. But there are a lot of associated problems with that kind of dynamics. The following illustration is taken by ...

After the painstaking setting up of the new Macondo, measuring all distance, paralleling the horns and time-aligning everything, after the setting up a correct level of the new channel’s attenuation (it turned out -2dB was necessary) I spent some tim...

Well that really is damn frustrating and admittedly very aggravating. After typing a rather lengthy and enthusiastic response, I somehow lost everything before posting and it couldn't be recovered. So we'll attempt to try this again, though adm...

A few months ago a reader of my site contacted me and informed about that he found a very interesting driver, that his is using and he is very excited about it. The driver is JBL 2490.

Sean, this subject is tricky. You might like your original Altec 802 better than your new 802G. (I did not
even know that they do new version). I have no doubts about your preferences
but how sure are you prefer the sound of the old driver juts bec...
|

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

This article was written by Johan Dreyer in 2006 posted at AA and the reposted recently at a Johan's local South African forum:

Somebody from AA was asking about electromagnet. The subject pup up here from time to time but this time Bruce Edgar uploaded an interesting comment. Bruce is not a typical AA Moron and if he says “inaccurate things” then it is not due to ignoran...

user="Newtohorn"]Thanks for all your inputs. I take Romy's
words that the Olympian sound is not what customized horn systems in horn
enthusiasts' room sound like. Of course, I wanted to hear the opposite,

I did a lot of listening lately and observed that there is
something in my sounds that I do not like. Over the years, one of my primary indications
of a properly built playback was the sentiments I'm getting from my recordings.
One of them is ...

the bad result during audio show does not mean anything, only good results
count. You see, there are zillion reason why during the show the sound might be
horrible. The inadequacy of the people ...

The kids are growing up and twins sleep fine and walk already.
So, the Bessnow’s household is calming down, a live-in nanny for sure helps…
With more time at my heads I am trying to finalize my playback in our new home.
I spent a few hours today t...

Rich,
I think it’s too early to seriously to talk about sound of your driver. As I understand you have no horn for this thing. Your comment that the driver goes all the way unto 8kHz clearly indicates that you used wrong horn before. If you stick a...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

One of the challenges I see for my midbass horns is to minimize hf output. The goal is to operate the horn in a bandwidth where it can cross to the higher horns, and have each horn function in their best sounding manner. My drivers are Altec 515-16...

Lately I have been thinking a lot, trying figure out what I
am and where I would like to go with Macondo. The Macondo base, the horns isle
is still there and I have no motivation to change anything. The conceptualizing
and assembling of what I hav...

My amp is a stereo 2a3 / 45 .
Lately I find my self listening in mono because of the area of my apartment and because I can focus better on the reproduction .
So this is not a stereo / mono discussion , just better for my needs .

[quote user="RonyWeissman"]A mid-bass horn for my Altec 515-8G drivers operating from 100-600hz [/quote]
Rony, I think your wish to have mid-bass horn with 515G is a bit faulty. A mid-bass horn for 515G shall be 50-600 Hz. Let me to explain. T...

Hello, Pawel.
I never heard nether about Onkyo HM-300MK2 or about
anybody who use it. It looks like it is one of many obscured Japanize drivers,
and they made plenty of those. A simple googling said that it has 2 inches
voice coil, duralumin di...

Romy, I have been trying to explain to myself what happened and how I got to it and trying to recreate this wonderful boiling point.
I tried to make a write up of all the steps needed in order to make it happen, but it is ever so elusive. I ...

Thanks for your comments, Romy.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 ...

Hm, very different and very opposite result, interesting. Are you using the same S2 diaphragm as I do – the metal suspension? If yes then it would be the only one explanation that I might come up with.
Sometime the compression drivers with horn form...

There is a guy named Ad in Netherland who makes looks like aluminums (but I am not sure) horns for 1.5 inch compression drivers. The first picture it looks like an exponential: W=39cm/15.4Inch. L=45cm/17.7Inch.
I do not know if Tractrix and the Fren...

This is of course a precondition. Of course we can’t list a „kit“ here. If we

I was pointed out to Steve Guttenberg’s video “Meet Joe, and
