Believe in Quality

Home Cinema from Only Two Channels

HDMI inputs and ARC make connection to smart TVs, game systems, and streaming devices simple. Setup menu is easy to navigate via on-screen display, Extensive subwoofer management are all more commonly found in multi-channel surround sound receivers. STEREO 70s gives you these features but streamlined in a device supporting 2 loudspeakers rather than more complicated multi-channel receivers.

High Resolution Audio

Slim and Elegant

Marantz design is timelessly elegant—an expression of the musical soundscapes the products create. Our philosophy of balance and symmetry is evident in our sound and our designs. Meticulously engineered in a compact chassis, STEREO 70s fits where standard equipment cannot.
