Design
The woofer is a 12 cm cone type (EAS-12PL50), tuned for good low-frequency response in a small cabinet. It has a UL edge, which cuts mid-range distortion. A large magnet and a sealed, low-loss yoke improve efficiency and damping. The horn-type tweeter uses a lightweight, rigid polyester film diaphragm, which keeps the mass of the vibrating system down. The enclosure is hermetically sealed, with packing between the baffle and the back plate to stop air leaking.
Context
