On-the-side additions to the Music Link series.
Despite the Marantz name, the LS-85 is a Philips product, developed in Eindhoven, which Marantz made a version of, just like the earlier and bigger LS-95 which was the FB1000 at Philips.
The 20cm low/mid driver has a cone made of a mix of polypropylene + carbon fibers and a bigga Ferroxdur magnet ; the mid/high driver is an Isophase push-pull ribbon - it moves air fast and accurately. Bi-cabling or bi-amping are possible, and the stand shown here wasn't an option but an integral part of the design ; it could be filled with sand for even more stability.
Marantz being Marantz and Philips being Philips, there is little else said by either outfits about the LS-85 and LS-95... Philips sold the originals in Japan, Marantz sold its versions in Europe - why make simple when complexifications are readily available ? Being a later item, the Marantz version had the Music Link logo, the original Philips doesn't.
