JBL VTX A8 ตู้ลำโพงไลน์อาร์เรย์ ขนาด 8×2 นิ้ว 3 ทาง 600 วัตต์ VTX A8 Line Array จากแบรนด์ JBL
The VTX A8 is a next-generation line array element that delivers JBL Professional’s flagship VTX A Series technology in a compact solution for small to mid-size rental and installed applications. The VTX A8 was designed to solve the diverse sound reinforcement needs of production companies, rental houses, theaters, houses of worship, as well as production applications requiring front fills, side arrays or other auxiliary support for larger-scale VTX systems. Proprietary JBL woofers and our latest-generation high-frequency transducer and waveguide technology, provides unmatched performance, efficiency, and a consistent 110-degrees of horizontal coverage. The A8 combines two 8” woofers, four 3.5” midrange drivers and two 2” high-frequency drivers in a single low-profile cabinet. Proprietary double-flared low-frequency ports, precisely calculated for greater low-frequency performance extend the usable operating range down to 49Hz. The VTX A8 shares the VTX A Series’ patented rigging mechanism and suspension system for streamlined deployment, while a comprehensive suite of accessories open up a world of configuration options.
Used on its own or in conjunction with the VTX B18, A12 or A12W, the VTX A8 expands the JBL VTX A Series to offer audio professionals a complete toolset for designing optimal sound systems for any application.

JBL VTX B18 ตู้ลำโพงซับวูฟเฟอร์ไลน์อาเรย์ ขนาด 18 นิ้ว 1300 วัตต์ VTX B18 ตู้ลำโพงซับวูฟเฟอร์ จากแบรนด์ JBL
The VTX B18 is JBL Professional’s next-generation single 18” subwoofer, designed to complement VTX full-range sound reinforcement systems. The VTX B18 features JBL’s new 2288H 18” woofer, engineered for improved linearity, increased sensitivity and extra-long excursion. The 2288H is based on JBL’s Differential Drive, dual voice coil, dual-gap technology, which delivers better heat dissipation, lower power compression and wider dynamic range than conventional single-coil designs. The B18 incorporates JBL’s patented Slip Stream™ double-flared exponential low-frequency port design to improve airflow and reduce audible turbulence, even at maximum excursion. The B18 shares the industrial design of the JBL’s VTX A-Series products and has the same width and suspension hardware as the VTX A8, allowing the two products to be used together in a variety of flown or ground-stacked configurations. The VTX B18 can be deployed in omni-directional or cardioid configurations, in arrays of up to 16 enclosures.
