[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...

Zako, TAD's newer drivers came about 10 years before the newer JBL's and the 4003 has 6 slits, not 5 as the sales material say.Rgds.e...

"TAD TD-2002 seems to have that "interesting" tone"The TAD TD-2002 has an interesting frequency responce, it goes as a technically perfect driver should up to app, 15Khz then there is an unusually softly rounded peak around 20kHz with an amplit...

Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that. I would love to use horns below 1 kHz but wil...

[quote user="Merlin"] Indeed the linearity of the Berning in comparison with the Lamm is quite remarkable, and indeed could be disconcerting to an inexperienced listener brought up on large increases on 2nd harmonic at the bottom end. [/quote]

[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...

[quote user="NBC"]Hi Romy, Since you have certain opinions on TAD/Beryllium sound, Im curious: 1) Which TAD drivers you evaluated (2001, 2002, 4001, 4002, 4003) ? 2) With what Fc horns? 3) With what horn materials? 4) With what Xovers? [/quote]Neil,&...

Hi Romy,
thanks for the links. Did you try any other TAD's than the 4001? Like the 2002 1" device or the 4003? The ET-703? Did you utilise the 703 to cover the top octave and a half and suppress the resonance? It's certainly my experience that the...

[quote user="Paul S"]Merlin, won't you at least put your amp in some sort of meaningful context, because it is a waste to continue this thread if you just treat it like a pissing contest.What speakers do you use? What sources, etc?&nb...

Coops, I think in some ways Romy is right in that modern commercial horn designs based on reference drive units do rather price themselves out of the market.
It's long been the preserve of the dedicated enthusiast and avid tweaker who is prepared ...

Hi Markus,
The realisation that in my implementation, going first order on the bass unit is an unacceptable compromise. I have never tried a third order PLL crossover but imagine the losses are noticable.
But I've heard the losses of putting a...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...

right from the entrance of phase plugs. In this sense, not even Bruce and Sam
did it right, I’m afraid to say. In many cases the driver and the horn are
designed by diffe...
