[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...

Not, really. I personally afraid all those “all the horn lovers” and do my best to keep them uncomfortable at my site. I d...

The only reason I don't have a giant WE system is that I can't afford it and I don't have room. I sold all of my WE and Lansing field coil gear to my Silbatone friend back in 1989, because I know he would never sell it, he was putting together a ser...

We had this exchange with Christopher Witmer, who lives in Japan, via the AA about the new driver form some small Japanese manufacturer. The dirt who runs that form has deleted the whole development. Hm, people wonder why for years I have a vocal and...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

[quote user="Joe Roberts"] At least I have significant WE experience! Romy, you have none to speak of, yet you are super-opinionated on the subject. Someday you might learn the truth. The big WE horn systems are a different league entirely from m...

The units that i put in my pictures JBL AND ALTEC A7 both designs have a resonance just like all wood that you would rap your nuckels on even 2 inch thick plywood will resonate at a given frequency, that goes for glass, cement, metal, they all do...

[quote user="jeff1225"]Roomy,I have read the posts from two years ago on your multi-cell horns. What was the final verdict? I don't see them for sale so I assume you've kept them. I'm curious where you stand on using 18 cell horns as the main midrang...

Gentlemen:I've thought about this mid-bass challenge for quite some time. I have tried many approaches.For the sake of my example, let's assume mid-bass to cover from 60-600Hz. That just happens to be the classic "decade". I have to fully agree with ...

Yesterday a local audio guy came over and I played to him my Altec 19 in the finally cleared fireplace room. While he enjoyed his frumpy music I paid attention to how unintelligent sound was. I do not know if it was Altec 19 or the electronics that d...

Looking at Vox as a glorified 2-way Altec speaker with tweeter and supertwiter with all " not optimal" choices ,folded 70's PA thunderbolt mid bass cab time misaligned crap ( Romy's opinion ) bi-radial Vitavox midrange suitable for derby races and d...

Ronnie,
The stuffing the back chamber in upper bass horn and stuffing a sealed enclosure have totally different purposes. In the firs case we need to decrease volume of the chamber in the second to increase it. The polyurethane foam spray is not foa...

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 ...

agh..well.. i can see that you'd never be over for a beer and listen session, romy! not that i wouldn't invite a curmudgeon such as yourself.. but my own system might not make the cut!i just finished off a little 2 way bms/altec system (and i d...

[quote user="vuki"]Anyway, my plan was to make powerful triode NFBless amplifier for relatively small money. I'm really satisfied with what I did. Maybe I should have done GM70 SE, but what would be my next project then?[/quote] The GM70 is a bitch a...

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...

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...

BTW, to illustrate my point. Here is typical Goto inhalation. In fact this is the better among others as to be typical the MF divers need to be lined up horizontally. I can hardly believe a person needed to be more Moron to voluntary arrange drivers ...

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 ...

Mats,
Actually I do not exactly understand what you are trying to accomplish. The Altec midrange after 4uF will roll at 3.5kHz-5.0kHz, depending of the type of coil you use. If you cut the MF channel so high then I would ask why you do so and why yo...

I have to admit that I hate the Altec 604 in the same way I hate a few similar drivers other companies made in the same topology. Jean Hiraga made a loudspeaker around Altec 604, I have no idea how it sounds. People who read my site know that I d...

It certainly has nothing to do with my ear or with being
acceptable. We attribute too much attention frequently to a topology/hardware and
too little to specific efforts over given implementations. So, what is the
subject? The Multicellular horns?...

Hi Romy,
I think my post is a little confusing.
The picture shows all the different drivers
used in these experiments. The Altec in

horn is the constant with the
