hi Romymy name is Angelo. I am swiss/italian, live in brazil the last 10 years . I grew up assisting my father buiding speakers and comercialize them in small numbers. I where listening for many years on Klipschorn replica with altec 416-8b...

Hi Romy,Its an Altec 416-8A driver in a ~100 Hz exponential horn, Jbl 2441 in 350Hz tractix, Aurum Cantus G1 tweeter and Eminence Definimax 4012 HO in ~30Hz Tapped horn.I just hooked it up and the highs are promising but I thought the lower end (200 ...

Jorge,With the risk of being called a moron, I actually didn´t do any calculations more than using hornresp to get a decent spl-curve.The driver properties a got from a guy in Denmark who renovates old altec drivers. The numbers probably weren´t accu...

[quote user="noviygera"]p.s from my experience of having a 500 sq. ft. listening room with 7 ft. ceiling and having two 18" woofers in a infinite baffle configuration, it is not enough to pressurize the room. I am talking about low and medium listeni...

Charlus,As you expressed here this would be an End of life speaker project, and I am sure you will not fancy any other speaker once you start with this, even Vox Olympian etc. Yes it will take a lot of money and a lot of time, but you will have fun...

I always thought that I have to have a dedicated thread where I would upload all those unhappy emails that audio-morons from around the world send me. This is so entertaining and surprisingly demonstrable! Here is I got just now. It comes from Kerry ...

I remember this guy from time spent at AA. He has probably tested about a hundred drivers by now, maybe more. It sounds like he has no expectations of using these "full range", rather wide range. Unlike the Lowthers that I still use OB, the Rullit ...

I was slowly looking for a compression driver that would go in my Fundamental Chanel down to 200Hz. The YL Acoustic 550N attracted my attention. Then I realized that it is the narrow throat type of the drivers, aka WE555, not exactly that I would...

I agree Steverino, IMHO Bass in the most tricky part of audio!
A couple of things I found out that help. Most importantly, Time Alignment! Not just between the channels crossing right to the next frequencies, but the whole system should be time alig...

[quote user="Macman"]Just realised that I had dual highpass filters on the TH, which more or less cut off frequencies below 50Hz entirely. A lot better now, still much to be made of course.[/quote]
This is very normal. People get the “building...

More technical data :Designed around the Altec 288 driver
and Altec 515B woofer, the new Latour, standing for "London western
type", has a custom designed and optimized crossover network. Overall
frequency response is rated from 30Hz to 20kHz with...

[quote user="be"] Instead of defining the ULF range from the reproduced instruments, it is much smarter to do it based on the first resonance frequency of the listening room, because the frequency response of a closed room has a 12dB/oct rise in ...

Hello
Everybody !
I am looking
for information regarding the Altec cabinet: 815a, particularly with 416
woofers.
Anyone is using it?
Now I a...

The example of the APS’ regeneration and the quality of sound attainable has clearly proved that class D is the way to do the things in audio electricity. I have been asking myself what is next? Well, this is not a question that I ask myself in a...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

[quote user="Jeffrey Jackson"] It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE bu...

I think we have to subdivide bass into upper bass from 100hz to whatever your midrange does and bass under 100hz and then maybe infrabass.
Front loaded upper bass horns are fantastic and I would say if you never heard one, you really nev...

Romy,
I'm also very interested in how you deal with a replacement for the 811b horn. I have not seen another hobbyist who has posted a suitable alternative with measurements. Its possible that the Azura horn recommended in the th...

The KOSS Electrostatic unit was still installed , so I removed and checked resonance .The resonance was 136 HZ. I then tested it in horn assembly and the result was the same : 136...

[quote user="Romy the Cat"]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...

[quote user="Romy the Cat"] In fact I do feel that
my MF and upperbass are very good integrated. But again, I might not know how
different it might be if it was otherwise. [/quote]
Exactly!
Some time ago I also thought my upper bass channel is ...

Another particle of a good Horn Propaganda. It was published in Sound Practices in 1994 and written by Joe Roberts. I disagree with quite many of the author’s statements but his strategic view that the majority of the horns and the horn installations...

How difficult is it to find 437As good enough for a phonostage? For commercial applications is it a dead tube. WE might produce it again when they stated to redo the tubes but the existence of the Russian 6C45P pretty mu...
