Commentary
A speaker system that combines the SB-RX50 technology with a more compact enclosure.
The unit uses a 22 cm coaxial 2-way speaker unit with a coaxial structure and a flat vibrating plate to obtain a sound without any peculiarity. In addition, by realizing the 360 circle identical directional characteristic of the point sound source, free layout such as vertical and horizontal placement is possible.
The woofer and tweeter diaphragms are made of mica material with high sound velocity (propagation velocity). The double-magnet structure and magnetic shield cover provide an anti-magnetic design and a strong magnetic circuit.
The enclosure uses a bass reflex design with a B4 front baffle and an A4 depth.
The all-round baffle also reduces the adverse effects of sound wave diffraction at the end of the enclosure.
