Actually I just went to the site and I can conform that the cretin removed form my posts some of my explanations of the Model 19’s shortcomings but explicitly kept my replies (edited!!!) to the idiots who suggested that I am not familiar with Altec b...

Thanks for posting the Vandersteen interview.It inspired me to try once more to tame my TAD 1601sthat reside in sealed 3cuft boxes. It worked, but the numbersare slightly shocking. 12mH translates to 100Hz, and 25 uFon 4 Ohm Altec 290’s in 260 Hz hor...

I had quite a number emails from different people who picked 515G or AK15X drivers and would like to build a midbass horn from 60-80Hz to ~500Hz. I played a lot with different 515 (B, E, D, A) and with different AK15X but I never went for the right h...

FWIW, I've done the cone doping myself, and my first reaction to doping paper cones is suspicion. Why does it "need" this, and how/why will it really "help"? But I injected this example only to set it apart from the [Altec] horn doping, r...

Hey Romy,
Goto makes 12" and 15" woofers at 100db. I recently found out they make a small two way system using an 8" woofer. The 8 incher's range is 55hz-8000hz so I'm thinking it might be a good candidate for use with 60Hz h...

[quote user="Romy the Cat"] Try to drop the Altec in 400Hz horn down to 1000 Hz -700Hz and arm your Oris with a MD driver with a good lover midrange driver (B&C of whatever you use) You will be able to go away with 4 channels… You have a lot of n...

I was thinking, Bill, that you now have S3s running down to 400 Hz. If you ever said what you are using below the S3s now, I don't remember. I have only heard the 15" Vitavox a couple of times, many years ago, but I did once own Altec Lansing 515Bs, ...

I went to eBay and searched for his diaphragms. If you look for the rest of the items he sells then you see that he sell vintage labels of Altec, Western Eclectic, JBL, Rogers, Studer… Well, in my books the people who sell it and those who buy it hav...

[quote user="caT"]Adding 1uf more and the horn being to sound like Altec horns…[/quote]Interesting. I'm wondering here if this is the key to eliminating the honkiness I hear in most horn installations. From your experiments, it seems that...

Trying to explore the upper bass channel reaching up to a Victor Sierra 360 Hz horn with an Altec 804 with a 4 uF oilcap, I first used my OB Supravox 215, then a B&C 8" woofer in a large BR originally used with EV 15" (the latter not good) ...

From that location the only frequencies that would be useable would be 80hz down, basicly a subwoofer. You Don't even have 10 feet from the face of the wall to work with. I still say you will not be able to use above 80hz from this location behind yo...

symbiotic diaphragms were never used in the 19's. this may be part of the "bad sound" that this guy was experiencing.they used the 802-8g driver with ultra light epoxy and aluminum diaphragm that allowed hf response up to 22,000 cycles when pairedwi...

audiofilofine, you need to examine your room and your entire domestic environment in order to see where and how you might make your pair of bass horns. Also, if they will be 20Hz horn then are you planning to use next chelas up as Altec MF driver? Th...

Is speakers like altec 19 have time aligned drivers? I think I have never seen in internet time aligned 3-4 way horn speakers with oken/jensn as a bass.Slowly I am closer to finish my first speakers with horns, the frame is adjustable (35-45cm drive...

I would like to build great horns for the bass as deep as possible and I use 4 woofer altec 416th.

Saturntube, thanks for the explanation. I thought that HR2 was just inspired by RCA but it look like it direct copy of it.

Hi Keith,Interesting experience you have as I have found running my 505TT with the 160hz le'clech horns between 320hz-1200hz (with first order slope) works best for my setup and using my 15" goto sg-38wn woofer to play under 320hz (which sounds very ...

[quote user="decoud"]Why not enclose it in a horn shape? After all, it makes sense for the facing surface to be circular rather than square, and a cone will have the best structural properties, as well as having the closest kinship with the rest of t...

Romy, you specifically mentioned Shindo, and this is a well-known example of the "Old Parts School" that seems to be able to channel It. Examples I have heard have all been simpler Music via simpler speakers, so I don't know how it works with big sym...

I look at it this way, it is all about your original source of prerecorded crap. Most of the problems with speakers are not the speakers it is the source of music the record album and the cd. Everyone is out of touch with the source, if you want good...

A few local audio guys temporarily donated to me some gear that completely out of blue made me to have my Opera Room operational. I have a big screen, some kind of a good projector, in few days I will have a good player. The sound is the Altec 19 and...

I would like to pass some observations on my about sound quality in my video room. The sound in my video room is what I would call very very good, I am not kidding – really good. It is delivered by Altec 21S speaker driven by Yamaha B2 amp and ...

[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 ...

This week is the High End Show in Munich / Germany. It is a typical Show, maybe something more interesting, there is a Demo announced with a Horn Speaker System I never heard before, Silbatone with a Pair of WE 15a, Bass with Electro Voice 30W + 2x A...

"Like live" is a statement I really like to stay away from but seeing that someone else also misunderstood me there makes me feel I did a bad job describing my views on that. Last statement in that direction: live music and recorded music are two com...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

Well, the Vitavox is also a "paper driver" that has needs like the Tannoy (unless it is the "horn version"...), meaning the size and nature of the enclosure will affect the Vitavox sound, as well. I always thought the Altec 515 Bs were OK up to 500 H...
