Yes, you`ve hit the nail on the head. I had read John Hasquin`s comment`s
which really set me to wondering if I was considering something fundamentally wrong by choosing a spherical tractrix or exponential horn
for the 70hz to 800hz range. If you`re right that John was refering to a cone driver in his comments then that would certainly simplify the issue.
Time alignment won`t be problem as I will use an active amp and crossover setup with will permit electrical alignment.

You`re response has been very much appreciated.

    hi ogima
    this driver is a sub basshorn driver, lowpass crossover should not be higher than 100hz. ( ideal is 50 - 60hz ) The best is to use a original ALE basshorn, ore one made on specifications similar as this one. This are the ALE original Horns for this driver :

    here the plans for diy :

    i heard this basshorn with your driver in japan :

    and even with the driver electronically time aligned, i heard clearly that the sound was coming from a long distance in front of me ( 12m )
    i recommend you to high pass it at 20hz, otherwise it will blow easily. Jean Yves Kerbrat wich uses this drivers blow it , at to get replacement diaphrama in japan is not a easy task, and expensive.
    I do not recommend this sub basshorn solution. It looks impressive, but the obtainable result is questionable. Mr. Marcel Roggero uses 12 Altec 515-8GHP ( 6 per side ) in his basshorn, and gets a clean 18hz.

    People in france who heard it say it is much better than the system from Jean Yves Kerbrat

      Hi Angelo,
      
      Thank you for your response. However, my intention is not to use the
      P 1260 in a sub bass application as it is a middle low frequency driver
      which Ale recommends in the frequency range of 70 hz to as high as 800 hz. Are you saying that you did not like the Ale sound from your audition experience in Japan due to the horn length or because of the Ale tone. A 70 hz to 800 hz horn is not really all that long ( much shorter then a sub bass horn by far ) and should be easily time aligned electronically. But if the tone was not pleasing that`s a whole other
      thing. Did you listen to the Goto drivers while you were over in Japan ? If you did,what was your impression ? Thanks...

        hi Dan
        
        for this driver you can see the japanese tachion site :
        
        http://www.tachyon.co.jp/~sichoya2/ale/horns.html
        
        here pictures of horns that may would work, however without specs to diy, but you get a idea :

        ore this Audio Note Mid-Bass Horn specification sheet, witch probably would work fine for your driver too, so you can diy:

        i did not hear goto drivers yet, only ALE drivers and Audio Note drivers ( formet YL ) with silver diaphragmas, at Kondo San's factory. Mid Bass of his system was effortless, transparent, dinamic, and somehow soft sounding and warm. I did like it.

        Ok Angelo,
        
        I will look over all the info you`ve sent. I`m glad to hear you liked the Ale mid bass. Good luck with all your speaker development projects...
        they look very nice. BTW, Romy the Cat shut me out of his site because he somehow got it in his head that I was you. Strange,strange fellow.
