The Yamaha A12M is a passive loudspeaker designed for live sound reinforcement and monitoring applications. Here's a description of its features and characteristics:1. **12-inch Woofer:** The A12M features a 12-inch woofer, which provides powerful low-frequency response for a full-bodied sound.2. **High-Frequency Driver:** It also includes a high-frequency driver (tweeter) to reproduce clear and crisp treble frequencies, ensuring a balanced sound across the frequency spectrum.3. **Two-Way Design:** The A12M is a two-way speaker system, meaning it divides the audio signal into two frequency ranges (low and high) and directs them to the respective drivers (woofer and tweeter) for optimal performance.4. **Passive Design:** As a passive loudspeaker, the A12M requires an external power amplifier to provide the necessary amplification. This allows for flexibility in choosing an amplifier that matches the specific power and impedance requirements of the speaker.5. **Rugged Enclosure:** The A12M is housed in a durable enclosure constructed from plywood, which provides strength and rigidity while minimizing resonance and distortion. The enclosure features a black carpet covering and a steel grille to protect the drivers from damage during transport and use.6. **Multiple Rigging Options:** The A12M includes multiple rigging points and a standard pole socket, allowing for versatile mounting options. It can be placed on a speaker stand, mounted on a wall or ceiling, or flown using appropriate rigging hardware.7. **Stage Monitor Design:** The A12M is designed to serve as a stage monitor, providing performers with clear and accurate monitoring of their sound on stage. Its wedge-shaped enclosure allows it to be placed on the floor at an angle, directing the sound towards the performer's ears.8. **Versatile Applications:** The A12M is suitable for a wide range of applications, including live music performances, DJ setups, public address systems, and more. It can be used as a main speaker, monitor speaker, or as part of a larger sound reinforcement system.Overall, the Yamaha A12M passive loudspeaker offers reliable performance, durability, and versatility, making it a popular choice for musicians, sound engineers, and audio professionals in various live sound applications.
