EF Series Has Been Upgraded for Higher Performance!
The PMC (Polymer-injected Mica Diaphragm) Series was a great success, proving popular with consumers and winning awards for excellence around the world. The new EF (Elliprical Form) Series is designed to build on that success, offering even higher performance combined with an elegant Yamaha traditional piano finish cabinet. The woofers, tweeters and cabinets have been refined and improved, and even the wiring has been upgraded, with Monster Cable being used to connect woofer and crossover network. The result is superb audio quality with music sources and the latest 6.1 and 5.1 channel movie soundtracks. Its the latest in home theater speaker design, from the leader in home theater: Yamaha.
Behind EF Series Superiority: the Waveguide Horn Conventional direct-radiating home speakers have broad directional characteristics that result in a relatively high proportion of reflected sound (you hear a lot of sound that has bounced off walls). Movie theaters, however, are designed to have a highly absorptive acoustic environment so multichannel soundtracks provide a rich sense of spatial expression. To achieve the same effect in the home, therefore, it is necessary to use speakers with a direct/reflected sound ratio quite different from ordinary audio speakers. This is especially true in multi-speaker home theaters, where there would otherwise be lots of reflections. Yamaha accomplished this with the development of the Waveguide Horn, creating the ideal home theater speaker.

The Waveguide Horn speaker shows excellent balance in the front direction, with the surround effect to the sides and rear is not adversely affected by reflected sounds.
Shaping and Controlling the Sound Field Waveguide Horns differ from conventional speaker horns in that their waveguide features a horizontal control angle of 135 and a vertical control angle of 120. This allows the sound field to be shaped and controlled for optimal spatial expression in home theater environments. The Waveguide Horn also provides a much smoother frequency response than ordinary horns. PMD Cone Woofer Makes These Speakers Ideal for Home Theater Sound Home theater speakers must combine high power capabilities with excellent sensitivity and dynamic range, while being designed to prevent listening fatigue. The new EF Series speakers meet these

PMDs superior characteristics help ensure outstanding sound quality. In order to effectively reproduce digital sound, speakers must have the following capabilities: wide dynamic range, high efficiency, sensitive response, and high linearity suspension. The PMD used in the EF Series Speakers plays an important role in providing these capabilities. Its strong points are listed in the chart. Density affects the speed of signal transmission and shows the speakers excellent linearity. Youngs Ratio represents strength, resulting in high efficiency and sensitive response. Absorbed Vibration Ratio is the value of internal loss; the lower this value, the lower the signal loss, so it also contributes to high efficiency and sensitive response. And finally, Acoustic Velocity represents the overall velocity of signal transmission, an important element in reproducing digital sound. With all these properties, PMD is a material perfectly suited to achieving the highest, most natural sound quality. The goal of digital sound composers is sound creation that permits the reproduction of realistic sound, including dialogue and sound effects, and PMD helps make this possible.
requirements by using a PMD (Polymer-injected Mica Diaphragm) cone woofer. This Polymer-Injected diaphragm is Mica Microscope Photo composed of 30% high quality white Indian Pearl Mica, chosen for the significant contribution it makes to sound quality. In order to maximize its distinctive qualities, absolutely no coloring is added to the material. Weve also varied the cone thickness, making it thicker in the middle, which has been shown to improve performance. The cone is extremely light, yet also tough and durable, with excellent response speed. High Quality Monster Cable Extremely high quality wiring, from the well-known Monster Cable Products, is used internally in each speaker to connect the woofer and crossover network. High Frequency Response Dome Tweeter The proven capabilities and durability of this dome tweeter made
it the ideal choice for these speakers. It can reproduce frequencies up to 35kHz and is powerful. The diffuser over the tweeter helps improve frequency response and directionality. Bi-Wiring Connection Capability (NS-777 and NS-555) Bi-wiring means that instead of connecting the speaker to the amplifier or receiver with two cables (plus and minus), you can use four cables: two for the woofer(s) and two for the tweeter. This decreases modulation distortion for purer sound quality. Beautiful Yamaha Piano Finish with Elegant Elliptical Form As one of the worlds leading piano manufacturers, Yamaha has a long history of wood-working expertise. The EF Series speaker cabinets feature the same luxurious and environmentally fliendly finish as our fine grand pianos.

To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference. Install the speakers in a cool, dry, clean place - away from windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming (transformers, motors). To prevent fire or electrical shock, do not expose the speakers to rain or water. To prevent the enclosure from warping or discoloring, do not place the speakers where they will be exposed to direct sunlight or excessive humidity. Do not place the following objects on the speakers: Glass, china, etc. If glass etc. falls by vibrations and breaks, it may cause bodily injury. A burning candle etc. If the candle falls by vibrations, it may cause fire and bodily injury. A vessel with water in it If the vessel falls by vibrations and water spills, it may cause damage to the speakers, and/or you may get an electric shock. Do not place the speakers where foreign objects such as water drips might fall. It might cause a fire, damage to the speakers, and/or bodily injury. Do not place the speakers where they are liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. Placing the speakers on the same shelf or rack as the turntable can result in feedback. Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into clipping. Otherwise the speakers may be damaged. When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken never to exceed the speakers maximum input. Do not attempt to clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. Do not attempt to modify or fix the speakers. Contact qualified YAMAHA service personnel when any service is needed. The cabinet should never be opened for any reasons. Secure placement or installation is the owners responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of speakers.
