N a t u r a l S o u n d S p e a k e r S y s t e m s The natural sound of Soavo. Music as it should be heard. the original sound of musical instruments, and of the human voice, so they should be reproduced with nothing added or taken away. Giving you this beautiful music experience is the reason we created the Soavo series. Listen to Soavo and discover how truly natural music from a speaker can be. At Yamaha, we love, understand and respect music. Were sure that you love music, too, and that when you listen to it, you want it to sound as natural as possible. We believe that “natural sound” is N a t u r a l S o u n d S p e a k e r S y s 3 2 t e m s Yamahas involvement and passion for music goes back more than a century to when we built our first reed organ in 1887. Now we are the worlds leading producer of pianos and other musical instruments and are involved with music in many other ways as well. We manufacture professional recording equipment, we design concert halls and we assist artists at concerts with regards to set up and sound tuning. This knowledge and experience benefits our production of speakers in many ways. In fact, the very first speaker we made was used in a musical instrument the Electone electronic organ. For the Soavo series, our speaker engineers took advantage of Yamaha expertise in many areas, including woodworking, metallurgy, acoustics, sound processing and even piano tuning. But the most important factor is our commitment to maintaining an extremely high standard of sound quality that we call “Natural Sound.” You can hear it in all of our musical instruments, and now we are proud to present one of the finest examples of Natural Sound performance we have ever created: the Soavo speaker series. 5 4 Speakers backed by over a century of music experience. Soavo and Yamahas Commitment to Music Soavo-1 sets a new standard in sound excellence, delivering impressive power and dynamic range, a wide stereo image and deep bass output. This three-way, floor-standing, dual-woofer speaker system achieves superb clarity from extremely low to high levels, and a full, spacious sound. With the Soavo-1 gracing your home, you will appreciate the fine qualities of your music as never before. 7 6 Natural Sound Speaker System Toshiyuki Kita Working in both Japan and Milan, Toshiyuki Kita has designed many successful products for German, Italian and Japanese manufacturers. His designs are in the permanent collections of museums all over the world, including the Museum of Modern Art in New York and the Centre Georges Pompidou in Paris. He also designs traditional Japanese crafts. 9 8 Beautiful design that compliments the beautiful music. Since you are interested in the Soavo speakers, you undoubtedly enjoy the finest music in your home. Naturally, you want your entire decor to be beautiful also. To ensure that the Soavo speakers are visually as well as aurally beautiful, Yamaha commissioned the world- famous designer Toshiyuki Kita to create uniquely attractive speakers that will enhance the atmosphere of any interior. Soavo Interior Maintaining the high standards of the Soavo series, Soavo-2 delivers extremely accurate resolution and finely detailed sound with an elegant and versatile design. This two-way bookshelf speaker system provides crisp and clear sound localization. Place it in any convenient location and prepare to be amazed as you hear every note of the music with razor- sharp clarity and outstanding sound imaging. Natural Sound Speaker System 11 10 13 12 Soavo Design Higher performance through innovative design. In order to achieve the most natural music reproduction, the Soavo design team spent five years of research, planning and development. They created a unique cabinet design, which is shaped and reinforced for optimum music reproduction. They also used the expertise of Yamaha wood craftsmen who produce our grand pianos, selected acoustically excellent wood, and gave it a high quality piano-type finish. Every material and design aspect was carefully considered, even down to the feet. The result is beautiful speakers that bring forth out the full potential of the music. Soavo Technology Designed and built to deliver Natural Sound. D R I V E R S Advanced PMD Woofer and Midrange Cones In order to provide very fast attack time (sound rise and fall), as well as excellent midrange clarity and bass response, Yamaha developed Advanced PMD (Advanced Polymer- injected Mica Diaphragm) cones that are extremely light, rigid and sturdy. They employ characteristics decrease unwanted resonances to achieve the smooth frequency response that results in natural sounding vocals. The midrange driver creates a feeling of presence as if someone is actually singing in the room, while the dual woofer design delivers deep and tight bass. a low specific gravity material called PMP (Poly-Methyl-Pentene) that is much lighter than either paper or polypropylene. Precisely determined amounts of mica and talc are added, which testing has proved contribute to the beautiful quality of sounds in the vocal range. These drivers internal loss Advanced PMD cone midrange driver and woofer Aluminium Dome, DC-Diaphragm Tweeter The high-performance 1” (3cm) aluminium dome tweeter delivers crisp and clear highs at all power levels. It employs a fully integrated diaphragm/voice coil structure called the DC-Diaphragm that eliminates extraneous materials for a cleaner sound. It is extremely light yet durable, and for a small unit transmits an extremely large amount of detailed sound information, resulting in a denser sound field. Germany. Diecast aluminium baskets ensure solid support for high stiffness, improving sound image localization and depth reproduction. The midrange driver is powered by a newly designed, compact and powerful neodymium magnet. Carved Wooden Port Each port is carved from carefully chosen, high quality wood. The port has very thick and rigid walls and a flared shape, ensuring a smooth sound flow that contributes to bass sound with a more spacious and massive feel. Tweeter Plate A diecast aluminium tweeter plate isolates the tweeter from cabinet vibration and provides a solid attachment for the tweeter unit, so the high range sound is clear and transparent, with no colouration. All Parts Selected for the Highest Possible Performance The edgewise-wound ribbon wire voice coil contributes to high resolution, exceptional sound detail and excellent imaging.

While maximizing sound clarity and imaging, the designers strived to drastically reduce internal standing waves and produce an expansive sound with an exceptional feeling of depth. Their solution was to create a cabinet with non-parallel sides, divide the woofer and midrange sections by a slanted partition, and strengthen the interior with large, vertical ladder-type bracing. Three-Way Mitered-Joint Construction for a Rigid Body Yamahas excellence in woodworking is used to good advantage in the three-way mitered construction of the cabinet joints. This technique ensures extremely tight joints so the entire cabinet behaves as a single unit, providing tight bass reproduction. Diecast Aluminium Stands The Soavo-1 is equipped with diecast aluminium stands that provide the necessary solid floor contact for tighter bass and increased stability. Yamaha developed the Soavo speakers to provide extraordinarily realistic music reproduction. We accomplished this through a combination of advanced speaker engineering, use of the absolute best parts and materials available, and an innovative cabinet design. 15 14 Large hollow centre coils Solen metalized polypropylene capacitors. C A B I N E T N E T W O R K S Independent Direct Crossover Connections Yamahas total commitment to achieving rich and vivid sound is seen in the design of the Soavo networks. They use the highest quality parts, including Solen metalized polypropylene capacitors of France and large hollow centre coils with carefully selected wire. Furthermore, rather than using printed circuit boards, each connection is individually soldered on a thick wooden board, providing larger, shorter signal paths for maximum sound quality.
