Does anyone know anything about Marantz ribbon speakers? ie. sensitivity, nett weight per speaker, build quality, range, impedence etc , etc. Apparently they did a model No. DD16 about twenty something years ago. About a foot tall for bookshelf application.
If anyone has a pair or knows something I will be very grateful!!
Many thanks

That could be Philips speakers. Marantz is part of Philips, and they had (have?) a ribbon tweeter and midrange.
the tweeter was the AD 21600/RT8
dim: 118mm x 134mm x 44mm (hwd if looking to the front)
rated impedance: 8 Ohm
voice coil resistance: 7 Ohm
resonance freq: N/A
magnetic flux density: 0.36T
mass: 770g
sensitivity: 92 dB/W/m
max noise power: 10W
they cross the 90dB line at 5kHz and again at a bit over 20kHz, rise to 92dB at7.5kHz and stay ther until 20kHz. -6dB at about 3.5kHz and 40kHz.
This from the 1990 databook. I have somewhere spec of the midrange, but that would need a rather serious digging...
