Amazing sounding baffle speaker, Zeiss Ikon typ: 31-06

Setup:


The Power of Goodbuy - Madonna - Sony CD Walkman line out - Heatkit AA-32 electron tube amplifier - one Zeiss Ikon 7in fullrange speaker on baffle - large room


Speaker magnet says Zeiss Ikon Magnetfabrik DEW DORTMUND


Baffle size is 20in x 20in. Baffle says ZEISS IKON Kabinenlautsprecher Typ:31-06


Amazing sound. So deeeeeep bass (baffles only drop at 6dB per octave, ie gentle slope) and great treble. Smooth midrange.


So boxiness bassmud coloration as there is no $&@&$ box.


Then the linoleum Pleiades Auratone 5C type speaker was connected. It sounded smaller, less loud with some bass, focused but not as clear. This cube speaker sounds better with the Pleiades 2N3055 one transistor single ended class A (electrons flowing all the time) low power amp.
