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...

I have long followed posts in this forum and wondered what the ultimate horn system sounds like. I have always liked certain attributes about the horn systems I have heard (Trios, Cessaro, Acapella, Altec, the usual suspects) but never to the point ...

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”...

Hi i want to replace my 802 G drivers with something that plays flat and has extended highs. I have several horns was thinking of using Radian drivers like the 1.4" 745pb i have some 800hz 1.4" tractrix horns to mount them on. Anyone have experienc...

Interning that the strings and are the primary beneficiaries of the “Injection channel” effect. It would be hard to explain to people who never were not in my room what the effect is but I would try. (Yoshi you have to visit me again and what I tried...

[quote user="Ronnie"] The room modes I thought I had to battle suddenly disappeared the other day when I decided to try stuffing the boxes a bit. Suddenly everything fell into place :-)I guess I can do better than using little cushions though... Do y...

I need to say that I did not do any experiments with any commercial audio equipment for a looooong time. Partially I have no needs as I do not buy anything and partially I have no interest. It is not that I have anything against commercial audio ...

Stefano, welcome to the club, not the GoodSoundClub but the club of understanding of what is going on.
The subject of drivers in Tailored Audio™ is complicated and one of the biggest problems in this complicity is to defeat the attitude of judgment ...

[quote user="MusicLover"] Romy, SS amps have a FLAT freq curve and essentially inaudible distortion. THey don't cause ANY sound. No one has been able to scientifically demonstrate that SS amps add any HUMAN AUDIBLE signature to the signal. While I un...

| agree with your feline wariness with regard to torch bearing disciples of any given faith, be they believers in Altec, Audio Note or even Vitavox. In the case of Audio Note the fervour has often been exacerbated by the activities, pricing and ...

the sad truth was the space, the finite funds, and the available bms pucks! the sad truth also, i suppose,the lack of available, and sensitive horn users to bounce off of!i could probably see what your dislike of the bms stems from-- i tried to...

Hi!Sorry for not spotting this thread before. I'm the member of this forum and I read it from time to time. I don't know what do you mean with "he is from diyaudio.com site"? I'm member of a few formums and newsgroups but I wouldn't say that I'm from...

Again, I am not insisting that the material of that horn will behave like a bell so much as I am suggesting that bell-like sounds will eminate from this horn. Is the difference clear? Some of those Altec horns were textbook exam...

Hello Roman,Hola from Hong Kong! How are you? Haven't been here for long time. I have a question at the back of my mine for long time, and it may have been covered elsewhete in your blog before. I am asking it here but do point me to the thread if it...

Hi all... yes, a clean power is paramount for a clean sound... I run my turntable and pre-amp on batteries and the difference in sound is amazing, while I never used outboard filtering on amps, BUT I have a public mains transformer at 10 meters from ...

Romy, what exactly was bad, and how?Honestly, my knowlwedge and objectives were in infancy back then. Also, it's been so long that my "memory" is probably crowded with parasitic ideas passing themselves off as memories. But I remember the 808 drive...

Romy I see were you are going With this horn worship for midbass. It is the correct thing to do "But you still will not be happy with the outcome because it does no go low enough. You will not be happy with 60hz. Then you will need something that ...

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...

Josh, thanks for sharing. Of course I have not listened to these speakers, but I can say their marketing looks and reads pretty much the same as other manufacturers who aim at wealthy nerds who want to own "the best". Altec-Lansing was very much li...

No mater how ridicules the title of this article sounds on my site but I was quite glad to see the in the May’s issues of Stereophile the Robert J. Reina review of Advent loudspeakers. I do not think that Advent’s review is a sign of some kind of sin...

The direction of lansing was the main factor of speakers not W.E. Just look at the phase plug on the W.E HF drivers and look at the phase plug on the lansing Hf drivers this is were it all went down hill. Your mid and Hf drivers from lansing took the...

[quote user="ayebee"]An observation that might only be of superficial interest to the thread: I don't think the speakers use Klangfilm woofers. The pictures are a bit grainy, but the dustcaps look far too big for the original Bionor woofers. I would ...

[quote user="Markus"]Interesting take on the Altec 820. No way can this be done for 20k. Looks like dipole bass with some attenuation for mid frequencies.[/quote] Markus, the price of this thing might be anything they want. They can set if $100K and ...

[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...
