Unicon, I would not argue that our ears just don’t care as much about amplitude as they do about phase; I have been pitching it myself. However, I think you do properly interpret the need of the “exact parallel sound from drivers”. The parallelness o...

Don't know the Vitavox, but some of the old 15" drivers sound good up to 4-500 Hz. For my own current project I will be crossing a modern 10" driver at about 200 Hz, for reasons of efficiency, and not planning to use the walls for baffle extensions. ...

Well, Tannoy tuned all their 10" monitors to play reasonably well down to about 50 Hz. Their monitors I heard were all variations of ported, with some of their "newer" monitors (70's?) using the ports to create more apparent bass, and those monitors ...

wow.thanks for comments.La Grande Castine will not be as expensive as Cessaro Gamma.i am sorry but i cannot answer to all questions, for several reasons you can understand.we have tested many drivers since the early prototype of La Grande Castine. BM...

Here is a link describing Meyer Sound's design philosophy, production and implementation:http://www.meyersound.com/support/forums/talkshop/drivers.htmThey began production of their own drivers to improve longevity and reliability in the field. These...

[quote user="el`Ol"]Titanium diaphragm drivers that are completely free of the titanium nastiness (you can believe me, I usually show strong allergic reactions to it) are the Eighteensound drivers with titanium nitride coating. I heard one in the...

Try thinking about it like this: Moving your ears 1/2" closer to all drivers in the system is not the same as moving a single driver 1/2" closer to your ears.jd*...

I think clearing this up this may be of benefit to other users who are building multi-way horns.
Let's say I've got two horns mounted on a frame. There's a high horn
above and a mid horn below and they are physically time aligned, meaning
th...

Romy:I think you may find the link and the shoot-out, of limited value as they are, of interest. The S2 did not fare well at all, not surprising really, given its idiosyncrasies and how difficult it is to get anything remotely acceptable out of it. h...

Gday was thinking about buying these for a mid bass horn or may be a bass horn one day. There in terrible condition other then I think they have two real vitavox cones in them even though one has been replaced. Note the crack also. But t...

Hello everyone,I have excellent news from Fane. After checking their old stock, they have now found and have confirmed that they have sufficient old stock of the 8 ohms or 16 ohms voice coils to offer everyone ordering a choice of 8 or 16 ohms.Qu...

I also am selling my JBL 2490 mid-range drivers and perhaps a collection of my original Aura 1808 drivers. The 2490 drivers are new and Auras are some old and some new. I just do not see myself to develop any inspiration to use them......

Romy,I half expected some kind of whipping from you which I fully welcome. I am guessing some of it is to see if I buckle and get all weepy under a critical look at my statements but hopefully you are just trying to possibly get me to clarify my obje...

[quote user="Jorge"]I tend to like drivers with plastic suspension. Radian makes retrofit diaphragms for JBL with plastic suspension, maybe they will help you achieve the tone you are looking for.
Extensions are easy to machine out of aluminum, eve...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

I have written in past about my lack of love to the BMS drivers. The crazy, as far as I concerned “annoyingly wiling” angeloitacare brought this subject to this forum while he was galloping across Web, “picking from graves” about his new dB-Design’s ...

Yes, it’s the drivers that inspired me to write up this thread. The response looks like it rises slightly atop but it is almost OK for this type of the drivers. Running the driver off the axis it is possible to roll off the HF rise. It is pretty much...

If you are correct there should me a large gap in the market for any company that really cares about sound. Returning to the topic of the thread, have you noticed wide discrepancies in the 'sound' of S2 drivers even between drivers manufactured withi...

[quote user="RonyWeissman"]The electricity comment is interesting as today I put on some jazz music and the HF is very snappy, excellent! I feel like posting on AA to ask people's opinons if it's the electricity or if my concrete horns are going thro...

We, the horn people, know what the compression drivers could do. The controlled dispersion, low distortions, low mechanical dependency, low magnetic anomalies, high efficiency, higher maximum dynamics and many-many more advance are well known. The te...

[quote user="be"]The best driver I have heard is the TAD 4003.
It does not use the secondary resonance of the suspension, as described by Duke LeJeune above for the TAD 4001-4002, to extend the response towards 20 kHz, but has a natural roll off fro...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

Very good point - I will direct Martin's attention to this. Visually, it looks like he did an excellent job on the 340 Hz horns, and the 160Hz horns will be rolled off at 1k anyway but nonetheless, will see what he reckons. Actually, no need - I just...
