Beovox M70 4 way speakers in teak cabinets $800.00
The Beovox M70 had the same midrange unit, a German-made ITT Schaub-Lorenz unit (LPKM/130/50 120T), classified by them as a 50mm (presumably the diameter of the voice coil) soft dome in a 130mm housing; the textile dome itself being about 55mm and about 65mm (measured) including its surround. The B&O speaker leaflet of the time lists it as a 2.5″ (6.3cm). The tweeter for the M70 was a SEAS H086 (25mm soft-dome unit)
