Yamaha STAGEPAS100 Portable PA System with Bluetooth

Compact design. Big sound.

Far more than just a speaker that amplifies your mic or instrument inputs, the diminutive STAGEPAS 100 delivers impressive sonic performance by leveraging some of the same technologies used in our high-end professional products. A powerful, high-quality coaxial compression driver combined with Yamaha’s FIR-X filters for the HF and LF crossover deliver sound pressure, precise phase response, and a natural dispersion that will ensure every nuance of your performance is conveyed loud and clear to your audience.

Coaxial compression drivers utilize a common motor structure sharing a single magnet, reducing weight and bringing LF and HF closer together to provide a more ideal point sound source. Since sharing a magnet reduces magnetic flux, lowering the sound pressure, these drivers use voice coils made of a light aluminum material called "CCAW" wound in a square shape referred to as "Edgewound" to increase magnetic flux and ensure sufficient sound pressure, and also feature a device called a "demodulation ring" that suppresses magnetic flux disturbance to maintain a high level of sound quality. Additionally, they are equipped with an air venting structure in the basket to reduce LF wavering at high volumes, a polyimide diaphragm to balance HF durability with smooth high-frequency characteristics, and a short aluminum horn for better directional control, durability, and heat dissipation. These compact units house advanced, state-of-the-art technologies.
