The Marantz HD 770 speakers were introduced in the late 1970s and are part of Marantz's line of high-performance audio equipment. They are floor-standing speakers known for their excellent sound quality and impressive bass response due to their larger cabinet design. The HD 770 model features a three-way speaker system, which typically includes woofers, mid-range drivers, and tweeters, allowing them to cover a broad frequency range effectively.
