Soavo Concept: Delivering Natural Sound
Soavo speakers are created by Yamaha based on our long history and rich experience, including over 125 years of making musical instruments and more than half a century of making speakers. In order to reproduce new high-resolution sound sources with the highest quality, the NS-901 series feature new speaker units and undergo extensive sound quality tuning to further refine their expressive capabilities. You can be sure these speakers will deliver all the aural excitement that music and movies have to offer.
New A-PMD Woofer reproduces high-resolution sources with richly detailed sound and abundant power
The 13 cm (5”) woofers adopt the new A-PMD with a paper cone upgraded for the reproduction of high-resolution sound. The use of a large ferrite non-shielded magnet ensures high drive power that provides prodigious bass volume. By utilizing high-quality parts such as a high rigidity aluminum diecast frame that dampens resonance, it reproduces bass with a deep sense of scale, achieving both power and speed, leaking out of the speaker cone. This means the full power of the waves is forced out through the airport, resulting in a clear, powerful bass.
Aluminum Tweeter Plate
A diecast aluminum tweeter plate isolates the tweeter from cabinet vibration and provides a solid attachment for the tweeter unit. This prevents incidental movement, helping to ensure that the high range sound is clear and transparent, with no coloration.
High-Quality Parts Including Solen Capacitors for the Network
The crossover networks employ the highest quality parts, including Solen metalized polypropylene capacitors and large iron-core coils with carefully selected wire. All parts are connected by directly soldering each one individually, instead of using printed circuit boards, further contributing to the rich and vivid sound. Finally, meticulous sound tuning ensures optimum transitions between drivers for smooth and natural sound across the entire frequency range.
