3-Way Bass-Reflex Tower Speaker System. The EF (Elliptical Form) Series feature Waveguide horns, PMD (Polymer-injected Mica Diaphragm) woofers and highest quality internal Monster Cable wiring for total enjoyment of digital movie sound and music sources, plus elegant Yamaha traditional piano finish cabinets.

Piano Black Design

The EF (Elliptical Form) series was designed with the prestigious Yamaha piano range in mind. The Piano Black finish is a 7-layer thick black lacquer which is the same glossy finish that is used on our grand pianos, which showcases the EF Series speaker design impeccably.

Fast, Quick, Responsive Speakers

Yamaha have been designing speakers for over 40 years. Our A-PMD (Advanced Polymer-injected Mica Diaphragm) cones are light, sturdy and extremely rigid. This ensures excellent mid range clarity and strong bass response from the drivers.

Monster Cable

All internal wiring within the EF series cabinets is done with high quality Monster Cable. Monster has built a strong reputation for high quality cables and accessories; a complimentary product for your EF Series.

 Natural Design Speakers

EF Series speakers are designed to give you the closest audio quality to actually being there. No extra colours or noise, just natural sound reproduction. They are designed to work in harmony with Yamaha receivers to ensure your recording is exactly as you remember it.
