YAMAHA CZR15 ตู้ลำโพง 2 ทาง 15 นิ้ว 800-1,600 วัตต์ สามารถปรับเป็นแบบ Passive หรือ Bi-Amp ได้
The Yamaha CZR15 is a 2-way passive loudspeaker designed for main/FOH and floor monitor applications. From live bands at outdoor festivals to DJ’s in clubs, the speaker is well suited for a range of live performance and installed sound environments.

The CZR15 requires 800W of power to drive the 15″ woofer and 2″ compression driver, which combine to provide a frequency range of 43 Hz to 20 kHz (-10 dB) with a maximum SPL of 129 dB. The rotatable horn allows for vertical or horizontal mounting to further adapt the acoustic dimensions of a venue.

The constant directivity (CD) horn was designed with the goal of providing smooth, level coverage across the intended coverage area, minimizing roll-off that is common in conventional horn designs.

To maximize performance, the CZR15 can be configured for bi-amplification, which allows two independent amplifier channels to power the woofer and compression driver separately. Yamaha recommends the use of a DSP speaker processor or a power amplifier with integrated DSP, such as Yamaha’s PX Series amplifiers, in order to set crossovers, limiting, and equalization to ensure the best performance.

The rear panel offers two Neutrik SpeakON NL4MP connectors, which are configured in parallel and allow for additional speakers to be daisy-chained. There are twelve M10 rigging points for permanent installations, as well as two pole cups (0 & -7°) for deploying in a mobile setting.
