Commentary
This compact 3-way speaker system can be used in various spaces such as inside or inside the car.
It has an all-honeycomb planar configuration with 14 cm honeycomb planar woofer for the low range, 5.2 cm honeycomb planar mid-range for the middle range, and 2.8 cm honeycomb planar tweeter for the high range.
The tweeter and mid-range unit arrangement can be rotated by 90 °, and can be either a bass reflex type (vertical) or a sealed type (horizontal).
The rear of the enclosure is cut at a 45 ° angle so that it can be placed horizontally in a corner or at a desk.
Equipped with an A (8 Ω) / B (4 Ω) hissing selection switch depending on the operating condition. Especially at 4 Ω, a filter circuit works to cut the high-frequency range to suppress the high-frequency range of car components, etc.
