Drivers are configured into a pair of front-to-front, isobaric (push-pull) configurations. The direct radiation from each front driver is combined with the output of the companion rear driver in a tuned vented enclosure. This Compound Force design enables more output and less distortion, while at the same time delivering four 18's in an enclosure no larger than a typical dual 18-inch subwoofer.\u003c\/p\u003e \u003cp\u003eThe custom-engineered transducers inside the as-418 are equally unique. Each feature a large, 4-inch voicecoil and ceramic ferrite magnet. Ceramic is a much better choice for subwoofer application where extreme excursions generate operating temperatures that can easily demagnetize neodymium components over time.  By combining the large voice coil with a ceramic magnet structure, we increased power handling and decreased power compression, while ensuring reliable performance that would be consistent year after year under the most demanding conditions.\u003c\/p\u003e \u003cp\u003eThe as-418 features a robust, multi-ply birch enclosure with extensive interior bracing and dampening materials to reduce unwanted flex and resonant frequencies. The cabinet is protected by a rugged, industrial grade polyurethane finish while the front features a protective steel grill with a water resistant powder coating.  Integrated handles allow for easy portable use.\u003c\/p\u003e \u003cp\u003eLike their full range counterparts, A Class subwoofers were designed specifically for working professionals seeking a better balance of performance, versatility and value.  The line provides options for adding low frequency impact to a broad range of sound reinforcement applications including houses of worship, theaters and auditoria, as well as portable PA for working bands, clubs or corporate events.\u003c\/p\u003e \u003cp\u003eEvery individual component inside the A Class subwoofers is optimized for each unique design. From transducers and cabinet architecture, to precision-tuned vents, crossovers and amplification, our team ensures that every element works at peak efficiency and in perfect harmony to deliver impactful and defined low frequency extension.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e  \u003cli\u003eQuad 18 LF drivers with 4 (100 mm) voice coils\u003c\/li\u003e  \u003cli\u003eDual isobaric configuration for extended low frequency response and compact footprint\u003c\/li\u003e  \u003cli\u003eVery low second order harmonic distortion inherent in push \/ pull isobaric design\u003c\/li\u003e  \u003cli\u003e2400 W\/4800 W, long term\/program power handling\u003c\/li\u003e  \u003cli\u003eUsable response down to 30 Hz\u003c\/li\u003e  \u003cli\u003eMax long term output 134 dB SPL\u003c\/li\u003e  \u003cli\u003eMulti-ply, cross-grain laminated birch construction\u003c\/li\u003e  \u003cli\u003ePerforated steel grills with powdercoat finish\u003c\/li\u003e  \u003cli\u003eIntegrated handles and stacking skids\u003c\/li\u003e \u003c\/ul\u003e","brand":"VUE Audiotechnik","offers":[{"title":"Default Title","offer_id":49571652628,"sku":"600103","price":10205.87,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2241\/9163\/products\/d3701b4c72308d990052bcfebe9c2e27.jpg?v=1504273993","url":"https:\/\/collection-import-export.myshopify.com\/products\/vue-audiotechnik-as-418-quad-18-inch-isobaric-subwoofer","provider":"collection-import-export","version":"1.0","type":"link"}
