Commentary
Marantz floor type speaker system.
A 30 cm cone type woofer is installed in the low range.
Uses 4-layer aluminized voice coil.
The mid-range has three cone-shaped mid-range and the high-range has two cone-shaped tweeters coated with acoustic material.
The middle and high range units are mounted on an air-coupled rotorable board to improve the sound diffusion effect while suppressing distortion. By rotating and fixing the rotorable board, it can be installed horizontally.
The unit layout uses symmetrical mirror imaging to improve stereo separation by making stereo images and sound diffusion effects symmetrical.
The enclosure uses a bass reflex system.
A diamond cut grill is used for the front grill to enhance the design and sound diffusion effect.
It can be placed vertically or horizontally.
