18 inch Loudspeaker

Using AD"s excellent speaker development technology, the speaker is designed for the bar"s main sound streaming, banquet hall, fixed or mobile performance installation applications.
The VTX-08 has a bi-amplifier drive technology that adjusts the tone with a special waveguide to make the tone clear and coherent. If the array is formed using VTX-08 to emit a stable constant bending wavefront, the wavefront range is 12° plus the number of speakers, and the vertical symmetrical coverage angle is 100°. The VTX-08 can be arrayed horizontally or vertically to meet different audiences. Seat distribution, VTX-08, VTX-08B with VTX-18SUB subwoofer, can deliver powerful, real playback, with a powerful low-frequency impact, giving listeners a unique listening experience.
The AD VTX series is a state-of-the-art modular line array speaker system designed for high-end bars, indoor and outdoor performances, banquet halls, performing arts centers, churches, theaters, and auditoriums. There are two handles on each side of the speaker for easy handling. The VTX-08 is a 100°X10° dual 8-inch 2-way full-range system. It uses two AD to develop high-efficiency neodymium magnetic high-power woofer and a 3-inch. The neodymium titanium film compresses the tweeters for a uniform and low distortion high frequency response. The AD VTX Series brings unprecedented fidelity, clarity and purity.
AD attaches great importance to the development of subwoofers, because ultra low frequency is the fundamental of music performance, and subwoofer is a natural extension of the system. The program for AD design of subwoofers includes: extensive linear and nonlinear measurements, long-term power testing, detailed computer modeling, comprehensive prototype testing/correction, and detailed comparative analysis to maximize the available resources in all bands to make the entire system The performance is optimal. Therefore, the VTX-18SUB subwoofer is the perfect complement and extension for the VTX-08 line array speakers. The VTX-18SUB contains an 18-inch high-power neodymium magnet unit in combination with an optimally tuned inverter cabinet for applications requiring maximum low frequency expansion and high sound pressure levels.
VTX-18SUB features
850W ultra-low frequency system, low frequency lower limit of 33Hz, laminar flow phase inverting hole increases peak sound pressure level and reduces turbulence noise;
The maximum sound pressure level is 139dB;
18-inch high-power neodymium low-frequency speaker unit.
