    I have waited for a response for 24 hours. I hope he PMed you. Since I heard these at InDIYana I have gatherer all the info you have put out there. I have been playing with it in PCD. I'd share it with you but you would probably say " not quite sure what you're trying to do there,but". Any way I sure hope you do share it someday. Unbelievable sound came out of those.

    Let's be fair to Pete here. You did make a point of this. However, I doubt you want a paper cone tweeter to go with your paper cone midbass, or a woven carbon fiber tweeter, or woven kevlar tweeter (although that's been done, just not very well). And you don't want a soft silk cone midbass either. So, what would a soft dome be a material match to in midbasses? Even in metal drivers it's not really a match since the material thickness and shape for an aluminum woofer and a tweeter are very different in ways to really matter. In the end, to me anyway, this postion of matching materials just doesn't seem to hold up very well. But, as you say, "to each his own."

    I guess you can tell I'm not much into "matching" driver materials for any other reason than aesthetic.

    Hey, you brought up matching driver materials, not me . . . :D

    Then where is the silk cone to match the silk tweeter? :rolleyes:

    To me it looks like a challenger to the SS D2905/9700, the copper-clad soft dome that also has a rising top end. Likely rising due to the lowered inductance profile. They use the same soft dome, 9300/9500/9700 I think. That makes it somewhat of a clone of the 9700, since the Usher was something of a clone of the SS line.

    The droop is gone purely due to the soft dome, another plus in my book. Sure looks like a great driver at a great price to me if the consistency is there. That's the hard part of soft domes (pardon the pun).

    No reason whatsoever. Jeff B did the Dreydel using metal cone mid woofer and fabric dome tweeter.

    And as anyone whose heard the Dreydel will attest, in this case, metal and fabric are a match made in audio heaven.

    Looks very feasible for a *lot* of projects.
    You prolly can't go wrong with either unit.
    Later,

    Thoughts?

    :rolleyes:

    This is just my opinion, but metal drivers get a "metal sound" when their breakup nodes are too prevalent. In the hands of a good XO designer, cone material isn't something you can hear. The only drivers I've ever heard with a totally distinctive sound are planars, but they're a whole different kettle of fish.
    I'm partial to planars. They are, in fact, what I'd pair to such a woofer.

    It's also where my belief in uniformity in driver material starts to become irratonal...:rolleyes:

    My point is, I'd never use the fabric RS with an RS (or any) aluminum-coned mid or woofer, especially when there's a great aluminum RS tweeter.
