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...

[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

Looking at the variety of exponential, parabolic, conical, tractrix, hyperbolic and whatever ales horn profiles out there I was thinking that we probably incorrectly approach the entire subject of horn profile analyses.
We listen the horns and we fe...

John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

[quote user="Merlin"]Romy,
if you see my post you will notice that I mentioned I did not know of any drive units that could successfully be employed. Can you list some?
Here is a typical high quality 15" cone - indeed one of the finest on the mar...

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

A week it trashing audio.
I finished with my client with wish I worked for a while, the contract with a new client kicks in 2 weeks and this week I do not work. Well sort of. This week is a big project on my aim – to reconcile the value of my...

[quote user="msaudio"]Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far...

[quote user="Serge"] The SIlbatone room was very large. They played an Edith Piaf record on a mono WE16B (or A, not sure). They played it very loud which I don't like, ever. I felt the system was made to show dynamics and it did it. The dynamic r...

de Charlus, this “are not afraid of cabinet resonance per se” is complicated subject. I have raised the topic in the “How to USE “Resonating Oops” in loudspeakers” thread:

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...

The closest to date I overlapped cones and horns myself was waaaay back in my time with Altec A7s. But I have since then and up to now heard many fine "hand-offs" from cone to horn, and my current project speakers hand-off cone to (very fast/short) h...

Hello,I just logged myself in so first of all: Hi Everybody ;)Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas ...

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 ...

No, the speakers like Altec 19 have time miss-aligned drivers. The majority of 3-4 way horn speakers with oken/jensn as a bass that you might see in internet also very seldom time-aligned but it is excusable as the DIY-audio people are mostly Morons ...

[quote user="haralanov"] For some unknown reasons, he later decided to change it with the sharp and artificial sounding fostex supertweeter. What might be his motivation? Logically appears the following question – is that Goto supertweeter so hor...

[quote user="ArmAlex"]The price is 167,000 Euro I was told. The material they used for bass cabinet at least looked like MDF. Sound was much better than any speaker I've heard in show, expect Cessaro which was wonderful. BTW Marten, Kharma, Focal, Ma...

[quote user="msaudio"]49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low ...

In our experiments, the more power we threw at the A7s, the better they worked. I heard some of the original "theater" version Altecs playing with their original "dedicated" Altec amps, and these sounded considerably better; but I never got ahol...

[quote user="manisandher"] For the past few months, I’ve been looking for a solution to a problem – how to recreate through speakers the same sound that I get through headphones. [/quote]I very much applaud to the desire to have speakers that do ...

Thanks for the wise, simple instructions, Roman, also useful to others, I believe... that's what I actually do since I - 'twas ONLY 15 months ago... - became conscious of the limits of my tuning-by-ear and got my IVIE IE-30 with Class A measurement m...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

I have order 4cu feet sealed enclosure for two 15 drivers. It
is relatively small box but I need to hit minus 6-8 dB at 50Hz. The collection
of the drivers I have would be following: Vitavox AK51 and 15/40, Altec 416B
and 515B. I like Vitavox tone...

Mats, I do not know who is Jeffrey is, anyhow, your horns look nicer this time. You need to figure out now what would sound more interesting: the 8PS21 at its higher knee or the Altec at it’s lower knee. The important would be that beside thier absol...

Let me list for you what I think drives sound quality to me:1. In room flat response at the listening positions2. equal decay at al lfrequencies off axis3. Adequate delay between direct & first order reflections. 4. Lack of distortion, or suitabl...
