Thanks for your thoughts, Mapman.
BTW, interesting story behind the German Physiks: The designer of the Dicks Dipole Driver specifically set out to design a Walsh driver without the cost constraints that Ohm works under. IOW, a no-holds-barred Walsh bending wave design. The results speak for themselves. The entry level German Physiks lists for ~$14,000, so if you can find a demo or used pair, they might be affordable. On the GP web site, there is a DDD driver unit for sale without a bass driver or cabinet, that you pair with a woofer/subwoofer. Someone better at this stuff than I might be able to save a few bucks with that.
All that said, I remain thrilled with my Ohm Walsh 2000s. At least I will be when my amp gets back from the repair shop.
