Electro-Voice ETX 18SP - subwoofer - for PA system

Key Features and Benefits:Signal synchronized transducers (SST) waveguide designThe waveguide is placed forward in the enclosure to help physically time-align the LF and HF transducers, minimizing the need for latency correction via DSP. Placing the port under the waveguide positions it in its ideal acoustic location in the enclosure without spacing the woofer and driver apart. The port location minimizes distortion and standing waves inside the loudspeaker. All waveguides are optimized using advanced simulation software and proprietary algorithms for precise control and lowest distortion.High-sensitivity, low-distortion transducer designEV focuses on creating high-sensitivity woofers and compression drivers that have linear frequency response and high power handling (competitors use smaller motor designs to save cost). The small diaphragm, convex-loaded phase plug and tight manufacturing tolerances of the DH3-B allows for high frequency extension to 20 kHz and beyond, and the high-sensitivity design achieves maximum SPL requirements similar to competitive large-format compression drivers. The motor designs are optimized using advanced modeling software and tested extensively, ensuring the transducers have low distortion at full output.Professional-grade componentsAll ETX Powered Loudspeaker components are designed from the ground up by Electro-Voice. No off-theshelf components are used. The handles, pole cups and amplifier chassis are die-cast aluminum, not plastic. 18-mm, 13-ply birch plywood with EVCoat is used throughout the product line, a combination that offers best-inclass looks and durability.Processing and controlSystem DSP presets support quick and easy setup via selections for type of use, crossover frequencies and top/sub combinations. Subwoofers include a DSP preset for "true cardioid" configuration. Employs the same proprietary PAL and TEMP limiters developed for EV concert/touring loudspeakers.
