I wonder whether an Altec 416 in a sealed enclosure plus transconductance amplifier would be the better solution for most people/circumstances....

The 811b horn is an unfortunate junk; it has to be unconditionally trashed. I wrote years back at the Altec forum, at that time I did not know that all of them are idiots in there, that Altec use of this horn in Model 19 is disasters. The horn is hor...

Yesterday a local hi-fi guy invited me to listen his new speaker. He picked up Altec Model 19 - I am known not to be a big fun of those speakers but they have own sound in the scale of non-demanding, off-the-shelf monitors. Upon expecting the speaker...

I was trying to strategize what would I do it tomorrow someone get in touch with me and offer my $50K. In another words what would I do to convert the Altec 19 to Cetla Ledom?This is an interesting discussion itself as it gives a blueprint for me...

So, two almost two years later and this contraption is still in my room and "ain´t goin nowhere" :-)Guys, I became obsessed with horn speakers and specially with Onkyo product so I would like to share with you my latest experiences.The speakers I tal...

[quote user="rowuk"]Oleg has a lot of bad press in Germany for unkept promises and defaulting on delivery of product. Just keep an open mind next to the open ear. The best product only serves a purpose if it a) arrives and b) performs.I really like t...

[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 ...

[quote user="DonM"] Romy, I have also noticed a difference in the response of my Altec 416A's with various amplifiers. My best rated amplifier the Bryston B60 was the worst and I could not listen to the speakers. I have been using a cheap Panasonic c...

[quote user="Romy the Cat"]As wonderful my Altec 21S plays video and pop crap as much it absolutely impotent to play any classical repertoire. In fat when I estimated it as 3 on the scale of Macondo 10 I meant the video concert and operas that I play...

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 ...

Stefano Bertoncello's posted at his blog a comment about Tony’s playback. I do not know him; I guess he is an Italian fellow or somewhere near Italy.

[quote user="Romy the Cat"]. What was your resonant frequency after loading? The 416 are 25Hz drivers, after loading and with two drivers it might be deep in teens. From the picture it looks like you keep the back chamber of extra large space, or eve...

[quote user="Horn Savant"] I think it's about the same as free-air resonance - backwave to entire basement. Precedent: pre-war theatre horns(open rear like Shearer/ERPI)(unlike post-war reflex tuned designs like Altec A4)(I don't like reflex boxes - ...

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 ...

As I have finished remodeling my new Opera room:

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...

Unfortunately I cannot reply to your question, Roman, as I purchased from herr Von Langa a N.O.S. pair of Altec 416-8B 15" woofers.BTW: while in Berlin, last May, Frank Schroeder performed an interesting, provoking "blind-test" using '50s and '60 Tel...

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...

[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 ...

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, if you do not mind then can you name you posts more identifiably and not with the same name? On the subject: I do not think that drawing shall be important to you. If you build as you say 20Hz horn then the design of the horn will be ...

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...

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 ...

Hi i am a new forum member and recently i built some speakers using Altec model 19 components 416-8b & 802 G. I built some 7.5 cu ft cabinets with two 4" diameter 5" deep ports this is the optimum cabinet size for the 416 i ditched the 811 horns ...

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...

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...
