With Tubes!! Have you tried the elderly speakers?

Have you tried the elderly German raw speakers made for tubes, that generally get high dollar on epay? Generally 5K Ohms. A few are electromagnetic, but most are permanent mags. Made for Tube amp reproduction, 6" and larger, (some for Philips. Nice radio (most) and theater sound systems. These speakers differ from most USA radios, and the better magnets were made by (I think) a long German name with 'magnet' in them. They've got my attention. Any experience with DIY tube amps and that load combination?(Forgive me, but I still think Norelco/Philips tape recorder trannys which are usually 3 or 4 times the size of Tellys, are really nice single-ended iron. Sorry for a repeat of the Norelco/Philips iron rant!! Previous post that you graciously responded to. So please skip that part as an unwarranted addition but I'm a bit OCD about them).
