Yamaha S115V 15″ Passive Speaker
Yamaha S115V PA Speaker at a Glance:
- Quality construction for long life
- Custom-designed Eminence drivers
- Oversized crossover coils for outstanding sound quality
These cabinets are constructed of high quality particleboard, chosen for its high strength and elasticity, consistent void free makeup and light weight. Another great benefit of this material is its environmental friendliness. Made from southern yellow pine, this material is both abundant and quickly renewable. Accurate CNC routing machines are used to cut every part, assuring consistency with tolerances of one ten thousandth of an inch. Skilled technicians assemble each cabinet by hand, rejecting any defects. Whether covered in durable carpet or the elastomeric spray coating, heavy steel handles and sturdy pole sockets make moving and positioning easy.
The speakers in the S115V cabinets are custom made by Eminence Speaker Corporation to Yamaha’s exacting tolerances. Woofers share design features like high strength curvilinear cones and Dupont Kapton voice coil formers. Oxygen-free copper voice coils and oversize strontium ferrite magnets are also used to provide high power handling and long life. The S115V’s 15″ drivers use cast aluminum frames to support the massive magnet structure eliminate flex and help dissipate heat. The compression driver that generates the high frequency sound uses a pure titanium diaphragm. This 2″ dome is one of the largest in its class, allowing for very high output and low distortion, without the aid of cooling fluids. It’s mated to a 90 degrees x 40 degrees custom designed CD (constant directivity) horn with excellent dispersion and response.
The S115V features crossover networks that divide the signal going to the woofer and compression driver, constructed with oversized coils, high voltage capacitors, and power resistors designed to provide the best possible sound quality and minimize loss. Overload protection is also included to protect the S115V’s components.
