Marantz DMS-350
(1984 - 1986)

Dynamic Flat Ribbon Radiator (DFRR) super-tweeter made of poly-imide resin film onto which an ultra-thin layer of aluminium is added by thermal process for 60kHz bandwith.

Polypropylene Laminated Copolymer (PPLC) bass driver for high internal damping, high rigidity and higher frequency response, powered by a NOMEX bobbin and heat-resistive OFC wiring in 4-layer form.

MYLAR-film medium/tweeter (HPF) for wide dispersion and high linearity ; edge and dome are processed in one piece with a poly-imide bobbin that is heat-resistant up to 300°C. OFC wiring and Ferro-fluid cooled magnetic gap.

Low internal loss metalized film caps and potted ferrite inductors make up for an efficient and DIGITAL ready crossover.

DMS stands quite naturally for Digital Monitoring System.
