4 Ohm Constant-Current High-performance all-weather speakers with a directed soundfield

Utilizing tough, environmentally-resistant materials and a state-of-the-art acoustic design, the AW-SD series speakers let you take Atlantic Technology’s outstanding sound outdoors. The advanced design of these speakers deliver detailed, articulate sound, for a musical listening experience. Each speaker contains a new fiberglass woofer design and a 1” liquid-cooled titanium tweeter that delivers highs beyond the audible range and smooth, accurate mid-range frequencies. The sound is genuine Atlantic Technology-detailed, powerful, and lifelike.

This series consists of three two-way models with new 4-inch, 5.5-inch or 6.5-inch high-performance super-stiff lightweight mineral homopolymer loaded fiberglass woofers that deliver tight articulate deep bass and clear mid-range while a 1-inch ferrofluid-cooled titanium tweeter with a powerful neodymium magnet structure produces extended high-frequencies beyond audibility.  The precision 12 dB/octave second-order crossover delivers a smooth response and outstanding sound quality with high 90 dB efficiency. Each model in the SD series has a 4 ohm nominal impedance ideal for installation requirements with standard amplification and wiring.

The drivers are mounted in an acoustically inert, heavily reinforced enclosure made from mineral-filled polypropylene. This is a far more neutral, less “ringy” material than is typically used with conventional outdoor speakers, and it contributes to the All Weather Speakers amazingly musical sound.
