A compact active speaker entirely made of aluminum and using an industry-first ultra-thick forging process (impact press process). Small, but the maximum thickness of the aluminum housing is 6 mm. High-quality medium to high sound is reproducible while suppressing resonance. Extra ornamentation is completely omitted. The seamless housing is made by directly carving sound holes. This achieves a highly durable body with less external degradation and a simple design, giving a sense of integrity. The power and volume are integrated to offer a simple operation of “just turning a single knob.” A green LED is installed inside the knob.
