Looks like TAD TD-4001 and TL-1601 or similar....

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 from app. 15 kHz.

(Note: I've neither seen nor heard these speakers)
Cessaro ALPHA:
TAD TD-4001 2" driver on tractrix horn with 56cm bell (approximately 250Hz). TAD claims response from 600-20KHz. Given that the midbass is essentially a direct radiator (theref...

Keith could you clarify? The TD 4001 has 1st order acoustic slope below 1khz when mounted on most horns. So adding a 1st order electrical slope to that surely does not make a textbook 1st order crossover.
If the 1601a is being run first order abov...

[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,&...

I understand they still use TAD 703 and 4001. The 11" is from Supravox. No idea about the bass drivers. I liked this Cessaro demo much better than in previous years. ...

Romy Hi ,just a couple of things , in the Gamma there is another 1 inch TAD driver between the 4001 and the 703 , regarding the placement of the tweeter ,it is only recessed 3 or 4cm ,at a useable frequency range there will be negligible diffraction ...

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...

The room is beautiful, and I love the tree stump "rack" with the amps, it is clearly a work in progress, but they already put in the "Western Electric" badges on! It talks a lot about their priorities I guess!They have what seems to be a midrange ...

Romy,,I agree with most of what you say....But good audio engineering comes in small tiny increments,,when JBL introdiced the coherent phase plug..I said so what?? then the moved the position of the magnet,,I said so what??But they were getting ready...

thanks for the good infoactually we are developing a full horn-loaded speaker the bass-bin is just inspired by Klipsch La Scala (just like Volti speaker) with curved sides. the mid-range consists of TAD 4001/Beryllium in Edgar wooden Tractrix horn an...

and especially "perfectionists" markets like Germany. Sound is of a secondary importance. I bet the new driver from Cesarro will be field coil driver because that's what peoplewant NOW. They want "the best" and field coil is now the best. Roman , som...

Hi,I have just received a Yamamoto A-02 amplifier from Shigeki. It is a 2A3 / 45 switchable amp, not available in the EU. It is supposed to be Yammies top amplifier. I bought it in JP and sent it to Shigeki for new 230V transformer...

"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...

Keith,
Interesting. Are you sure there are first order slopes on your speakers? Having played with those drivers I cannot see how it can be done. Or are you just talking of the electrical slope on the 4001?...

[quote user="be"]The TAD 4001 and 4002 have a number of sharp narrow resonance peaks in the range 10kHz-20kHz[/quote]
I would think it was lover – somewhere around 8kHz. That was exactly what did not like in the TADs – it was some ...

Thanks Gregm. It is interesting that I completely forgot the TAD PT-R9. I was looking at it 5-6 years back and spoke with AudioKinesis ‘Duke, who reportedly knows them well. My reservations that time were the very same as now: with 97.5 dB/W sensitiv...

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...

Hi Romy and othersI am in the initial stage of planning a new home, which will have a dedicated music room. I noticed Romy in another thread you were impressed with the rough stone walling. This looks like a great way to disperse reflections. What I ...

I never like anything TAD does. They used to have many years ago a very interesting 14-in driver, bass driver but still in this category is there very many good alternatives. Whatever they do has a huge infliction of compression. Back in 2000s I ...

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...
