Marantz LS-70 (1980s)
Documentation on the Marantz LS-70 is thin. The record shows a floor-standing loudspeaker from the 1980s. It is a three-way design rated at 110 watts nominal power handling (170 watts maximum), with a frequency response of 28 Hz to 35 kHz, 8-ohm impedance, and a sensitivity of 92 dB/W/m. It was a big piece of hardware. The listed weight is 23 kg per speaker, which fits the forum description of it as a "large, heavy speaker."
One forum account, quoting a contemporary French review, called the LS-70 "une excellente enceinte" - an excellent speaker - particularly good in the mids and highs, but lacking deep bass. The same user reported that the LS-70 paired nicely with the Marantz PM-54 integrated amplifier, which suggests it was meant for use with Marantz's mid-to-upper-tier electronics of the period.
Beyond these basics, the record is silent. No exact production years within the decade, no original retail price, no cabinet construction details, no crossover information, and no driver sizes have been documented.
