Product introduction Coaxial 2-way speaker 10cm woofer, 2.0cm tweeter rear bass reflex system In response to the high range of up to 40kHz, suitable for hi-res listening, optimal coaxial 2-way speaker in AI-301DA. "LS-301" is taking advantage of the accumulated know-how in the S-300NEO, coaxial 2-way speaker that has been developed to match the AI-301DA. Similarly S-300NEO, in coaxial unit tweeter is mounted on the same frame that plays the woofer and delicate high-frequency that emits intense kinetic energy, but you will need a good frame to a more robust and energy balance, and Air Dump the kinetic energy of the woofer by Center Pole System reliably converted to air vibration as sound, with minimal impact on the tweeter, you will be able to drive each of the unit in an ideal state. Moreover, bass reflex port located on the rear side, so that the air flow in the enclosure produces the optimal bass reflex effect has carefully designed the position and size of the bass reflex duct.
