M18B / M18W

Product Overview   

The M18B extended low-frequency subwoofer is designed and manufactured to deliver accurate and powerful bass frequencies. It is a high-power, compact subwoofer system. The M18B is used as a single subwoofer in a subwoofer/satellite system or as multiple subwoofers as part of an expandable large-scale sound reinforcement system with excellent efficiency and control. The subwoofer is stackable. This is the most powerful low-frequency supplement to the CAT KING full-range series speakers. The low-frequency driver is a high-power 18-inch woofer with a 4″(99.6mm) heat-dissipating voice coil and 220mm magnet. Its design is the result of the latest improvements in compact subwoofers, which can reproduce the bass frequency range quickly and controlled .
The M18W is an active subwoofer. An active sound system means that the power amplifier is mounted on the cabinet. This brings some advantages:
reduced setup time, daisy-chain signal and power connections for the entire system or by group without additional amplifier racks, saving truck space, sound quality and performance are optimized for each component inside the speaker, and network control can monitor each component of the system .



 

Applications  

Due to their rugged construction, they are ideal for bars, concert halls, nightclubs, road shows and AV

Onboard integrated active module
It is recommended to use with XCA series audio processor to obtain the best product performance.

It is recommended to use the MT1000 power amplifier to achieve a more perfect sound field effect.
