TAD ET-703 LinkMAGNETIC
CIRCUIT. A high-energy, rare-earth cobalt magnet is used in the
magnetic circuit that, together with powerful soft iron for the pole
yoke and plate, provides a high magnetic flux density of 20,000G. ...

compression drivers are the way to go as far as i am concerned but obviously performance depends on the horn lens.my beef with ET-703 is that i don't understand its horn or whatever it is. if not an explanation i would like to see maybe some po...

You could source used TAD tweeters for ~$1K pair .They sound exceptionally smooth and extended .More so than infamous T-350 and with better "tone" which may be relevant since your 288 are tonaly "dead" according to the Cat. Who knows, he may be right...

Yes, there are a lot of paths.I can see that many DIYers are very much stick on crossovers, changing capacitors, choosing slopes in digital filters - FIR or not FiR and so on.I know very experienced people who now say that with digital crossover he d...

Coops, I less care about the attacks on me, I know that I am a pH-indicator of Moronity among audio freaks. So, if some specific idiots out there are not happy about me then… it is good for me. The higher we climb in mountains the stronger wind and l...

Sorry Romy. Which loudspeaker are we talking about? Do you have a picture at all?
As for the Cessaro mod, it didn't sound very different to me - certainly not worth the effort. I'd be interested to know where they crossover to the ET-703. The Alph...

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...

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...

I find it pointless discussing the "sound" of a drive unit as it will be totally dependent on the implementation within the system.
I will say the ET-703 is best seen as a supertweeter, and used to cover only the top half octave and the ultrasonic...

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...

There's no plasma tweeter on the Cessaro. The tweeter is the TAD ET-703. The HK owner has a gold-coloured horn for the tweeter, but there's no plasma driver. I'm pretty sure the horn on the Lansche plasma tweeter is a good bit larger than the horn on...

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...

I have to admit I have no idea and did not experiment with matching horn loaded tweeter to big ,direct radiating "extended range' MF channel. I'm not sure it's doable. I was speculating on the reasons why the owner of Moscow instalation switched from...

…and I hope you did put your ET-703 tweeter in a time aligned position, did you?
The AD1 tube was one of those original “better sounding” triodes. I have a quite few of them; in Telefunken 1936-139 radios (I have 4 or 5 of those radios them in my st...

Putting together a speaker system that ticks all your boxes is a lot like doing anything else well: it is fine to experiment in order to find your range and learn your options but once you choose a path you must stick to it. Chopping and changing i...

Vasyachkin,
I have different view about “modifying products” as any product is always implying something very generic but I have my own needs. Probably not “modifying” but adopting would be better but it is not the subject in here.
