I have a good friend in Indy who is moving West soon. He has a pair of Acoustat 1+1's with passive cone woofers and a matching Acoustat TransNova Twin-200 amp, all stock, original owner since new. He said one woofer cone needs to be re-done, other than that I assume they're in good shape.
$1,000 for the package of both speakers and amp. He might separate them, but is mostly interested in selling just the speakers.
They'd be very difficult to ship, so pickup/delivery only near Indy. PM me here and I can put you in touch with him directly as he is not an AC user.
Thanks,
Tom
