So what became of this project

    Stumbled across this by accident and the propopsed driver seems very nice. Not quite as much excursion as the current tdx models, but more than the M and an even higher effeciency…..

    I will try to ask John about it…

    I guess you won’t see that anytime soon, due to John needing to put TD6 and TD8 in full production.

    Hi just wondering about this still. John said in one post that the td 10-12 cones were heavier than planned by a bit and he had lighter cones coming? Just wondering if he ever got a different material available to him. If I decide to use a td 10 in my car I think I’m going to have to use 1 magnet instead of two and that will cut my effeciency some. If I could get that back via a lighter cone, even if it costs extra that would be great.

    I’ll try to reach John again about it, he’s been hard to reach lately hehe ! 8)

    John told me that lighter TD10 and TD12 cones was something that Nick was really hoping to do. It could add a little bit of efficiency but until we get to a point where we can afford a large quantity of cones like this, it just isn’t practical here, so unfortunately, not possible for now.

    As for the TD15 prototype, he will take a look at that link and I’ll try to update you later.

    As for the TD15 prototype, John never had any interest on that prototype before, no one asked him to build it. What that is was a standard TD motor with the Dipole coil. This makes a very low inductance underhung midrange.

    If you are really interested in it, I guess John could custom build it for you, since it’s standard parts. But it will not be cheap… probably as expensive or more expensive than a standard TD15M. 8)
