[quote user="Jeffrey Jackson"] It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE bu...

Mats,
Actually I do not exactly understand what you are trying to accomplish. The Altec midrange after 4uF will roll at 3.5kHz-5.0kHz, depending of the type of coil you use. If you cut the MF channel so high then I would ask why you do so and why yo...

Mats, I do not know who is Jeffrey is, anyhow, your horns look nicer this time. You need to figure out now what would sound more interesting: the 8PS21 at its higher knee or the Altec at it’s lower knee. The important would be that beside thier absol...

Let me list for you what I think drives sound quality to me:1. In room flat response at the listening positions2. equal decay at al lfrequencies off axis3. Adequate delay between direct & first order reflections. 4. Lack of distortion, or suitabl...

Unfortunately its $1000,- total... Its not fixed, i can still do alot with that though.Alnico is better but only available in vintage drivers right? How does neodymium compare?The Jbl's seem to fall off fairly quickly. I dont need flat to 20K b...

Romy,I have seen this a few times with JBL and Altec drivers. This phenomena occurs more often in Alnico magnets than any other type of magnet. When a magnet is recharged, it is blasted with a very strong magnetic field. There is really no way to “ha...

Nice post Romy, you're probably right, I can't say since I've never listened to a pair of speakers that really told me "what can be done". I've always owned and listened to speakers that are commercially made, and I've had to choose among the ones th...

hello kids, a few weeks ago i started my hunt for a pair of speakers....i've been attached to my big system with a pair of headphones for the past year and feel its time to get some speakers to listen to music with (plus, i think my ears are now...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

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...

Hi Romy and all,
first of all, my name is Henry, with a "Y". due to an Irish grand-grand-grand father called "O'Henry". the O' was deleted when my grand-grand father was born, due to a silly servant of registry office. :-) all my horns uses the calc...

of MTM arrangement of two TAD 1201 in <100 Hz Horn ? I assume they would both work in the same frequency range . Also JBL LE8 is only 89 db driver and it doesn't look like it can take any power . Difference in efficiency within the channels would ...

There are a couple ways to look at it.The project could be taken from the same sort of perspective as Great Plains, id est, simply new manufacture as a replacement for a 'historic' piece of a equipment. If it can sound close enough to the original th...

[quote user="RonyWeissman"] The HF sound is very quick and weighty , which can be quite nice on classical guitar for examlpe, but the tone is not clear enough, meaning for example cymbal attacks don't have enough metallic ring to them, nor enough blo...

Hi Romy,
FYI: The previous photo of some unknown persons "pile o' horns" appears to be:
Upper midrange: 1" TAD TD-2002 mounted to 650Hz Edgarhorn
Supertweeter: Fostex T90A or T925A.
Lower midrange: ...

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

After the painstaking setting up of the new Macondo, measuring all distance, paralleling the horns and time-aligning everything, after the setting up a correct level of the new channel’s attenuation (it turned out -2dB was necessary) I spent some tim...

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...
