Speaker Driver Subwoofer Aluminium 700W 4 Ohm 90dB 26Hz - 600Hz Ø30.5cm
Dayton Audio's Reference Series subwoofers are based on the quality and performance of the excellent RS range, adapted for subwoofers. As with the entire Reference Series, these subwoofers feature ultra-low distortion. Second-order, third-order and intermodulation distortion is kept extremely low thanks to 3 integrated circuits in the motor structure. The spider, made of aramid fibers and featuring an efficient ventilation system, provides uniform excursion. The anodised aluminium cone, rubber suspension and custom bowl give the speaker a unique high-end design.
