    Are these drivers still in development? I finally have a vehicle that can easily support the 3-5inches of mounting depth these things will probably require lol.

    Nothing has been completed on these yet. I expect before the end of the year though.

    Looks like the TD8M would work nicely with the TD18. Will there be a preorder? What is the ballpark on pricing?

    stryke on #11037

    Individual pricing would be $249. Not expecting to do any preorders though. Maybe a short time introductory price but as of now that isn’t planned.

    Sounds good hopefully that works. I’d like to get a set for christmas hehe.

    I ran into a few issues but will hopefully be finishing up the first 16pc samples this week. If all goes well, I will be able to start taking orders on them soon.

    Exciting – keep up the good work!

    Will there be a LO8 available as well…?

    There will be a Dipole 8 using the cloth surround which will already have decent efficiency.

    any updates on when the td8’s will be ready ? would a td8m or td10m work better for a mid used with the td15h ?

    It depends on the tweeter used, but either shouldn’t have a problem crossing to the 15H.

    Will you be going active or passive?

    Bump for updated info on release and specs?

    Face on #11046

    No specs, but John posted on his Facebook page that they are available for order.

    Anyone able to source more info on these or taken the plunge and ordered any?

    Here are the initial parameters

    Fs: 76hz
    Qms: 7.9
    Vas: 11.3L
    Cms: .22mm/N
    Mms: 20g
    Rms: 1.2kg/s
    Xmax: 4mm
    Sd: 190sqcm
    Qes: .27
    Re: 6.7ohm
    Le: .15mH
    Z: 8ohm
    Bl: 15.5Tm
    PE: 300W
    Qts: .26
    1WSPL: 94.7dB
    2.8V: 95.5dB

    A TD8X will also be available but we need to get that finalized yet.

    Any way to get these with d8 coils or even just a single 4ohm? Also is any type of apollo upgrade available? Wouldn’t need it for the inductance so much as the extra powerhandling, particularly if a d8 or d4 coil is available 😆 At 500 for a pair, the price is a bit hard to swallow compared to many other pro audio designs, but I know these are very nice speakers and John has a small operation.. So I’m def considering these.
