[quote user="Bud"]You need to find an individual who can design series crossovers. Both JBL and Altec used these, because they sounded best. You will need to look for an individual near where you live because they will have to test the drivers as...

my vitavox S2's finally arrived today.i was not expecting great results with all the warnings i read on this site,especially with the klangy stock 4 cell 330hz vitavox horn.i know refinement when i hear it.i have heard avantgarde's duo, trio,i even 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...

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...

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...

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...

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

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

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...

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) ...

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 ...

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...

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...

[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...

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...

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 ...

It is entirely possible to find and develop something of relative value working with a challenged toplolgy, even if the limitations of the topology dictate that "ultimate" results will fail to reach the Aural Summit.If you hear something that wo...

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...

Just to share with you with my ideas about the Scepter 500 clones. I´m not sure if I will use the w3801 bass drivers. I felt in love with Altec 416 and quite frankly I very much doubt that Onkyo would sound better or equally good. It surely doesn´t s...

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 ...

"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...

[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...

[quote user="Romy the Cat"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...
