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 the design progresses...

The exceptional 15-inchers would be two fitted in two categories: the bass 15-inchers and wide-range 15-inchers. It is imposable to think about the exceptional and wide -range 15-inchers and do not mention the 1946 -1973 production of the Tannoy Dual...

[quote user="MusicLover"] Higher even order distortion sounds richer and makes the sound "more live" to most people. YOu can get that anywhere in the signal chain. [/quote]
I know about it but it is NOT a reverse statement. It is very frequently tha...

What's there to speculate about ?? Speakers are rare and expensive and the principle is old JBL altec 19 solution. It is 100dB efficient probably from 80hz up .Whats the purpose of your post ??Did you hear them or looking for encouragement to b...

Hi!You are probably familiar with this one... It's the closest to a multi-cell tweeter (well, maybe because it actually IS a multi-cell tweeter, but only 6 cells) I've ever seen...picture of Altec 3000hRegards,Anders Boman...

I understand your position on compression and not wanting to screw up the tone. The Community M4 driver is the perfect example of how NOT to build a 4” exit compression driver. First, the cone/dome material is garbage. Neither the sandwiched aluminum...

I agree the "period" closing needs more words, Roman.The P.A. horns/drivers were mounted in stadiums, convention centers, maxonic halls, cinemas, theaters, everywhere was needed a broad music or speech dispersion, trouble free operation and high S.P....

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...

[quote user="Romy the Cat"I have a very clear idea what kind elements I might be using in there and the whole Cetla Ledom ides is very much cleared to me. There are just two subjects that I do not know at this point: time delay for bass channel Can Y...

I have been intrigued by the Altec or similar Multicellular horns for a while. At least, in the midrange application of 500hz - 5K they look very interesting. I doubt of their high frequency capabilities but for midrange duty with a suitable 2" drive...

Have you read the thread on Altec 19 becoming 21S?http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=13135#13135The Opera room thread is also relevant. To answer your immediate question, an EV T350 with a small enough cap can s...

I always advocate that a civilized audio-practicing person must have one playback. I very much did not like the Morons who have multiple duplicating amplifier, speakers and multiple listening rooms. For sure they all produce slightly different fl...

HI, Dietmar from Germany uses a diy multicellular horn for his JBL 077-tweeter http://chaudioroom.com/Photos/CH1505%20Dietmar-6m.jpg By the way, i´m searching construction plans of Altec 1505, 805 or 1005 for a complete DIY project. Any suggestions? ...

[quote user="Wojtek"]I use regular Lowther DX4 (ENABLED) . I don't think the 250-400 is stellar and I'm still waiting for the extension to try small throat for lower midrange (2,75") (B&C 8P21E driver) for 200-1000Hz .[/quote]Look...

Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

A somehow-related thing is "texture", and - of course - what we want is the "availability" of a range of musically relevant textures rather than textural "overlay". The S2 and the Altec 808 had this potential, but I never heard it from the JBL 375, ...

hi Pauli had already Altec horns, and comparing them to wood horns, they really sound poor. What i really doubtis if someone is able to hear the difference between high gloss finish/ high porosity surface of horns.I really doubt abought that. I...

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...

This is not a klangfilm MF Driver, it is a RCA MF Alnico driver with phenolic diaghragm and bakelite rear cover. I have seen a few of these and they sound pretty good for a driver that is good from 300hz to 8000Hz. Sounds alot like a altec 290 driver...

Marc Henry-In the 6moons write-up, you mentioned the Altec 515 re-issue not being satisfactory for your purposes on the Grande Castine horn. I presume the specific 515 variant you used was the 'g' type (designed for horn loading) rather than 515'b' ...

Hi Romy,If you have a moment between setting up your gear in new room, can you point me to the thread where you discuss suggested wood horn finishing techniques? I can't find it.I am hopefully on verge of placing order for my first mid-bass horn for ...

Paul,Well it would be silly for me to insist that I'm absolutely correct here, as I too am only basing my analysis only on what I see, and what experience I have been able to amass (some profession-related, a little in...
