The Definitive Technology AW 6500 puts worry about sound quality and speaker resilience to rest with fully sealed speakers that perform wonderfully rain or shine. Its BDSS driver coupled to the racetrack-shaped, pressure-driven low bass radiator, and pure aluminum dome tweeter provide an accurate reproduction of vocals and instruments and rich, deep lows while limiting distortion. The speaker's air and water-tight design and non-resonant, rugged PolyStone enclosures allow it to be fully exposed to the elements and still reliably deliver indoor speaker sound quality for years of outdoor listening enjoyment. Integrated galvanized steel mounting brackets and unique enclosure shape ensure a full 360 degrees of rotation. The speakers can be placed just about anywhere while directing the audio to reach everywhere.Total Frequency Response: 40 Hz 30,000 Hz.
