Don't find much info on the Iwata horns.Do you have any links so I could learn more about them ?

How does the Tad 4003 compare to the 4001 and 4002 ? From what I have read
it seems as though the Jbl 2440 or Altec 288 are the best for tone and nuance,how do find the Tad in this regard and the newer Jbls ?

In absolute terms the newer compression drivers are significantly better than the old.Of the ones I mentioned the TAD is the only truly low colouration reproducer ,easily running with high quality low eff drivers in the tonality race.
My JBL2435 have been modified and sound identical to my 435Be.Exciting to listen to with massive drive but compared to the TAD a little shut in and busy sounding ,but still second best.
I love the 2440 with the aquaplased 2450 SL diaphragms. It is open and relaxed sounding,but lacks the speed and detail retrieval of the 4003.These are currently serving as mid drivers in Khorns in our tv room producing fatigue free sound on BBC to Barney.
The standard 2440 can send shivers down your spine on violin and horn reproduction.However I suspect this is secondary to resonances in the upper treble. It also lacks in detail retrieval compared to the above units.
The Japanese Gotos are on their own planet. At the same time stunning and frustrating,as fragile as an old Jaguar or Maserati and just as exciting.
Detail on Iwata horns can be found in the now defunct French magazine l'Audiophile

  greetings...
  
  couldn't help but read your feelings on Goto.. and I agree 100%... do you think there would be any interest in a Be replacement diaphragm with a proper voice coil former for the 370 series drivers?
  
  I was thinking that before I sent $$$$ to japan again, I would just develop a better and stronger diaphragm for them...
  
  thoughts?
  
  Peace,
  Me

    Many years ago I collected vintage Jaguars. Being inherently poor I could not afford a proper car-so despite a garage full of vehicles my wife and I often had to walk.Then one day I snapped and sold them all (well almost all of them). Now I get slightly nauseous when I see a Jaguar.
    
    I am afraid i feel much the same about Goto now. There are aspects other than the diaphragms.. On some occasions the voice coils would scrape.I got the feeling that the weight of the magnet would cause shift over time and they had to be realigned now and again. Add to that a slightly histrionic Japanese person accusing me of being clumsy and listening too loud and just generally being stupid and the fun starts wearing thin.
    
    Finally there is the sound: Piano reproduction is so riveting and lifelike and suddenly you notice here and there is a note that should be there but is just missing-bizarre.

      I, too, got the same lecture... that any tube amp voids the warranty.. all tube amplifiers oscillate and ring... I listen too loud... etc, etc, etc...
      
      but I still hear something I like.. maybe I am just still young and dumb enough to try to play with fire... (ouch!)
      
      I think the reliability issue with the tweeter and upper midrange drivers is the voice coil former... but I figure if I am replacing that, then a Be diaphragm is an obvious thing to try... I think the diaphragm wrinkles that resulted from the pressing are the cause of the frequency response aberrations...
      
      Peace,
      Me

        If you can cook up replacement dias that are field replaceable and Be to boot ,I'll be first in the queue

        greetings again...
        
        I think you will have to send me an email... I can't announce "products" here.. against the rules...
        
        but I do already have a price quote.. have to buy ten... the issue is really the mounting to the front plate.. such a small gap in these things... I will likely have to have that front plate... but not the whole motor structure.. assuming that they are all the same.. (and you know Goto)...
        
        big laugh...
        
        Peace,
        Jeffrey

  Thanks for your insights on these drivers.
  
  If you were unable to get the Iwata horns,what do you recommend for the closest replacement ? The Tad horn is highly regarded and copies(don't
  know the quality) are available.
  
  I am interested to know about your complete system using the Tad 4003.
  What are you using for other drivers/horns and crossover type,range,
  slopes ? Cut-throat's comments have me thinking about first order slopes.
  It seems as though they would make the compression drivers sound aggressive and maybe overpower them unless crossed very high.
  Any thoughts ?

    Click on the A next to my moniker.This will lead you to my profile.Click on my system for detail.
    For other horns ,I'm afraid you'll have to ask someone else. Sawdust is not my favourite pastime so I stick with what I have and love.

      but what a killer looking system......love the way the bass horns are integrated into everything , house,system,decor....
      
      great job, too bad I wasn't in South Africa to have a listen...
