Yamaha CBR12 12" 2-Way Passive Loudspeaker

The Yamaha CBR12 is a 12-inch, two-way passive loudspeaker from Yamaha's current CBR Series. It's a step up in size and power from the CBR10, offering a more robust low-end response and higher overall output. The CBR series is designed to provide high-quality sound, versatility, and durability at an affordable price, making it an excellent choice for a wide range of portable and installed sound reinforcement applications.

As a passive speaker, it requires an external power amplifier to operate.

Here's a detailed look at its key features and specifications:

Transducers and Acoustics:

• LF Transducer: Features a 12-inch cone woofer with a 2-inch voice coil, specifically designed to handle higher power and deliver robust, impactful low-frequency performance. The larger woofer provides more low-end extension and punch compared to the 10-inch CBR10.

• HF Transducer: Equipped with a 1.4-inch compression driver with a 1.4-inch voice coil. This slightly larger compression driver (compared to the CBR10's 1-inch) can often handle more power and deliver a smoother, more extended high-frequency response.

• Constant Directivity Horn: The HF driver is coupled with a newly designed 90 H x 60 V constant directivity horn. This horn aims to provide wide, consistent coverage, ensuring the audience hears clear sound regardless of their position.

• Bass-Reflex Type Enclosure: The cabinet is ported to enhance low-frequency response, contributing to a fuller and more impactful sound.

• Frequency Range (-10dB): 48Hz - 20kHz. This indicates an excellent, extended full-range response for a 12-inch speaker, capable of handling vocals, instruments, and various music genres effectively, often without needing a dedicated subwoofer for lighter applications.

Power Handling and Performance:

• Power Handling (Noise/Program/Peak):

  • Noise (RMS): 250 Watts

  • Program: 500 Watts

  • Peak: 1000 WattsIt's essential to match these ratings with a suitable external amplifier. For optimal performance and speaker longevity, an amplifier that can provide continuous power around the "Program" rating (500W at 8 ohms) is generally recommended.

• Nominal Impedance: 8 Ohms, making it compatible with most standard power amplifiers.

• Sensitivity (1W, 1m): 96 dB SPL. This is a good efficiency rating, meaning it can produce significant volume levels with moderate amplifier power.

• Maximum SPL (Calculated Peak): 125 dB SPL. This signifies its capability to deliver substantial volume.

Enclosure and Durability:

• Lightweight, Durable Enclosure: The cabinet is constructed from lightweight, yet rugged plastic (polypropylene), making it highly portable and resistant to impacts, scuffs, and scratches that can occur during transport and setup.

• Finish: Textured black finish.

• Steel Grille: A heavy-gauge steel grille with a powder-coat finish provides excellent protection for the drivers.

• Integrated Handles: Features ergonomically designed, integrated handles (usually two side handles) for comfortable and secure carrying.

Connectivity and Versatility:

• Connectors: Equipped with dual NL4 (Speakon compatible) connectors and dual 1/4" phone jacks. This allows for flexible connection options and easy "daisy-chaining" to link multiple CBR speakers from a single amplifier output.

• Pole Mount: Features a standard 1-3/8 inch (35 mm) pole socket on the bottom, allowing it to be easily mounted on speaker stands for optimal positioning and sound projection.

• Optimized for Floor Monitoring: The cabinet has an optimized 50 wedge angle, making it highly effective for use as a stage monitor. Its symmetrical design allows it to be used on either side of the stage.

• Rigging Points: Two (2) M8 rigging points are provided, allowing for permanent installation applications using optional eyebolts or speaker brackets.

Protection Circuitry:

• HF Protection: Non-resettable overload protection (usually a light bulb or similar device) is often included to protect the high-frequency driver from excessive power and potential damage.

Applications:

• Main PA for Small to Medium Venues: Suitable for live bands, DJs, and various events where a robust full-range sound is needed. Its extended low-end can reduce the need for a separate subwoofer in many situations.

• Stage Monitors: Highly effective as floor monitors due to its optimized wedge design.

• Mobile DJ Setups: Provides clear and powerful sound for music playback, with good bass for a full-range experience.

• Presentations and Public Address: Delivers clear and articulate speech.

• Installed Sound: Suitable for permanent installations in bars, restaurants, and other venues.

• Rehearsal Spaces: A durable and reliable option for practice.

The Yamaha CBR12 is a popular and well-regarded choice for those seeking a durable, good-sounding passive loudspeaker that strikes an excellent balance between power, portability, and value. Its versatility for both FOH and monitor applications makes it a practical solution for many live sound needs.<
