77 series speaker system.

The Woofer employs a 280 mm Woofer unit that expands the playback limit to a lower bandwidth by an optimum balanced aperture design for the enclosure internal volume.
The high-rigidity pure cross carbon diaphragm has been further reduced in weight and made non-resonant, and has acquired flexible follow-up performance capable of responding quickly to minute signals.

The mid-range uses an 80 mm dome unit, and technologies such as the SR structure (staggered rib structure), voice coil integrated molding, and aluminum edge-wise winding have also been introduced.

The tweeter is equipped with a dome type diaphragm of SR structure, and this is equipped with lightweight technology and tuned.
