As the flagship of the A Class subwoofer family, the formidable as-418 installs four custom-engineered, 18-inch drivers into a compact enclosure comparable in size to most dual-18-inch subwoofer designs. 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.
The 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.
The 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.
Like 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.
Every 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.
