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...

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...

say how much the old man is involved in all this cult and noise around him? I've also read all the poetic stuff on the site and can't say that this mystical aproach is not appealing. I had the impression that Sakuma just entertains himself makin...

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 ...
|
I do not think that you really can trust an answer from someone willing to tell you what to do. Sure, the Klughorn is a great thing, but I have never heard it suitable integrated - which says NOTHING about the horn and driver but a lot about those us...

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, ...

[quote user="RacerXtreme"] Hi. First time here. So this is where all the horn lovers go...... [/quote]
Not, really. I personally afraid all those “all the horn lovers” and do my best to keep them uncomfortable at my site. I d...

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 ...

Romy I have not herd so much doulble talk in a long time. Some of the best sounding drivers on the market in the last 60 years, were for sound reinforcement. I do believe, in a 2 way speaker system crossed over at 800hz with a good wood horn i wil...

Hello Romy,
I understand the difference between the kind of "basshorn" pictured here and the proper compression-horn that you use. It is true that many DIY-types like to make basshorns in their garage without much thought to technical consideratio...

[quote user="RonyWeissman"] It will drive either my Tannoy Gold's full-range, or my 3-way system (Altec 515/Vitavox S2/EV T-350 or JBL 2450). I could also use it just to drive the Altec 515 and use my current 300B to drive the MF/HF of my...

HI "Hifiordie" I want to tell the readers here that this guy is seriuos and has some serious talent.Unluckily for him he has been bitten by the same insect that got us and is obsessed by horns, please do listen to Romy and try to balance your life b...

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...

Another very quick post - I have guests arriving from Japan in a couple of hours. Will respond more thoughtfully when I have some free time.University Dean plans: Mouth - 1080 in^2Throat - 78 in ^2S(d) - 132.7 in^2Compression ratio - 1.70Path lengt...

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 ...

I was sitting in my fireplace room; eating my freshly cooked oyster mushrooms and listening a master dub of Munch and BSO take on Damnation De Faust. No matter how primitive the setup was in this room the experience was enjoyable even sound was annoy...

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 ...
|
John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...
|
[quote user="jessie.dazzle"]For your rear chambers, as they will be adjustable, it would be smart to go with a max volume that is larger than the max you estimate to be necessary. [/quote] The size of rear chamber is something that dials in the compo...
|
Thanks for all your inputs. I take Romy's words that the Olympian sound is not what customized horn systems in horn enthusiasts' room sound like. Of course, I wanted to hear the opposite, that enthusiasts here get the sound in that ballpark, but it...
|
well i never thought i would be opening such a pandora's box with this combination.firstly,the drivers have the plastic surrounds(whew,lucky!i know the diaphragms are potentially harder to source than the drivers)what indicators or criteria would mak...
|
Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...
|
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...

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 ...

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...
|
Jorge, not to stoop to a shopping list, but I thought I also mentioned the 375 in the post where I introduced Rullit. Anyway, I meant to. Since there is no mention of the 375 there now, I will drop it again. This was the driver I lusted after in my...

I have seen that people online react surprisingly to my post above. Hey are accustom that I am hyper-demanding and tough for production of DIY speaker attempts but above I suddenly proposed to relatively mediocre speaker to become the become th...

[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...
