 Product Overview  

The VF218SUB extended low-frequency subwoofer is designed and manufactured to provide accurate and powerful bass frequencies. It is a high-power output subwoofer system. The LA218SUB 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 two 18-inch low-frequency speakers with excellent performance 280mm magnets. The 5″ (125mm) inner and outer voice coils use heat dissipation technology to minimize cone driver power compression and ensure long-term reliability.  And it can reproduce the bass frequency range quickly and controlled . This subwoofer is constructed of 11 layers of cross-laminated birch plywood with a solid mortise and tenon structure, which provides accurate and fast acoustic response without coloration due to enclosure resonance. 



Applications  

Due to their rugged construction, they are ideal for bars, concert halls, nightclubs, road shows and AV rentals
It is recommended to use with XCA series audio processor to obtain the best product performance.

It is recommended to use MT1800 power amplifier to make the sound field effect more perfect.
