With its 18-inch low-frequency transducer, driven by 1,200 watts (peak) of Class D power, it provides an extended bass range with detailed low-end response down to 30 Hz. Despite its power, the AIR18s is portable, compact, and lightweight, featuring a rugged birch plywood tour-grade enclosure. It's easy to transport and ideal for mobile applications, as well as simple to install, with integrated provision for the included caster wheel kit, ground-stack provision, and ergonomic handles on both sides. The AIR series subwoofers are easy to set up—use the signal processing controls and presets. Set them for standard front-of-house use or boost the bass with the Mo' Bass preset. Reverse polarity, use the low-pass filter to set a crossover frequency, adjust the power amplifier main output level, even disable the grille LED for installations, all with the simple touch of a button. A variable alignment delay properly aligns your three-way system. Most subwoofers are essentially omnidirectional, which can cause stage feedback and make monitoring difficult. Creating a subwoofer array helps keep excess energy away from the stage and audience. The AIR series subwoofers provide the tools needed to create these arrays with ease. Most importantly, the AIR18s sound great, delivering exceptional bass clarity and natural musical reproduction. 18-inch low-frequency driver with 3-inch voice coil Class D power amplifier 1,200 W (peak) Maximum SPL 129 dB peak at 30 Hz Frequency response 30 Hz to 150 Hz 2 combination XLR and ¼-inch line inputs and two XLR direct outputs Easy-to-use DSP performance presets: Normal (typical FOH use) and Mo' Bass (extended low-end performance) Position adjustment presets: Normal (no array), Cardioid (ground-stacked cardioid array), and Endfire (cardioid endfire array) Fully variable low-pass filter (set crossover point) with presets for AIR15, AIR12, and AIR10 Alignment delay (adds relative time delay to full-range speaker) and polarity switch (reverses summed input signal) 2 convenient ergonomic side handles, ground-stack provisions, caster wheel provisions (wheel kit included), and disableable front-panel LED Rugged birch plywood enclosure with tour-grade finish, 17-gauge steel grille\u003c\/p\u003e","brand":"Presonus","offers":[{"title":"Default Title","offer_id":53993323397453,"sku":"2779106105","price":755.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/205852-large_default.jpg?v=1779916779","url":"https:\/\/musicdelivery.net\/de\/products\/presonus-air18s-subwoofer-attivo-da-18","provider":"Music Delivery","version":"1.0","type":"link"}
