New 44 series small speaker system developed as the next generation monitor series.

The 17 cm cone type Woofer is carried in low-pass.
A special polypropylene cone is adopted as a diaphragm, and low distortion is aimed at by laminating a high polymer composite material on a pulp base. Moreover, by using the SFG magnetic circuit for the magnetic circuit, smooth energy response and improvement of the input resistance are realized.

Dome type tweeter is carried in the high region.
Pure titanium is used for the diaphragm of this unit, and it is molded into a dome of 25 micron thickness with original technology and it is carried. In addition, by combining a diamond edge pattern and a reinforcing rib that gave a hint to Japan's origami workmanship, we have acquired superior characteristics up to 27 kHz ultra high region without sacrificing efficiency.

Bass-reflex system is adopted for enclosure.
