Yamaha YAC-VXS10ST Pro Surface Mount Dual Voice Coil 70V Subwoofer - 10"
Yamaha Commercial 10" dual voice coil subwoofer for low impedance systems
VXS series “S” model subwoofers are ideal matches for VXS and VXC series speakers, smoothly extending the low frequency range with superb sonic quality for bigger, more true-to-life musical reproduction. Although no larger than a compact surface-mount speaker the VXS3S delivers solid, natural-sounding low-end reinforcement, while the VXS10ST make even more low-frequency power available for situations that require maximum bass authority.
Low-frequency Enhancement Methods
A number of methods are used to enhance low frequency response in speaker enclosures. In bass reflex designs, a tuned port in the enclosure boosts low frequencies emanating from the rear of the speaker unit. The VXS10ST adopts this method, specializing in more powerful low frequency reproduction. The problem with this approach is that as the enclosure becomes smaller or thinner, the size of the port must be reduced accordingly, resulting in increased resistance and correspondingly reduced bass enhancement. Bass reflex designs are not always suitable for compact enclosures. Passive radiator designs avoid the use of a port, instead boosting bass response with a tuned passive “drone cone.” The passive radiator method is more suitable for compact enclosures, but the passive cone tends to be heavy, requiring some form of firm, durable suspension that can reduce efficiency. The directivity of the passive radiator also places restrictions on where and how the system can be installed. Original Yamaha SR-Bass™ technology employed in the VXS3S suspends a four-sided diaphragm on only one of its sides, using the resonance of the diaphragm to enhance the system’s low-frequency output. There are no limitations on the shape and materials used for the diaphragm, making SR-Bass™ technology applicable to a wide range of speaker designs, including compact models. Yamaha offers 2 choices. That is compact VXS3S and powerful VXS10S. Please select the best model for your application.
Satellite Connectors Optimize Balance
The VXS3S and VXS10ST have satellite connectors on the rear panel, minimizing the number of amplifier channels required to get a system up and running. And since the VXS3S and VXS10ST support high-impedance connections, it is possible to connect low-impedance satellites while the subwoofer is connected to a high-impedance system, for example. A built-in high-pass filter is automatically applied to the satellite speakers, providing exceptionally smooth, natural frequency crossover from subwoofer to satellites.
