THEATRON PERFORMANCE SB21
Ultimate Home Theater Subwoofer with Profigenes. The SB21 is equipped with a 21" long excursion woofer. The enormous dispersion area enables a brute dynamic, which is unique in combination with the small depth of only 40 cm. Of course, this subwoofer is also characterized by a high efficiency of 99dB (1w/1m).
From stadium concerts to large-venue cinemas, Theatron Performance subwoofers deliver the ultimate in dynamic and level performance. Designed specifically for low-frequency effects, these home theater subwoofers use glass-fibre reinforced cone materials and a ribbed shape with high-temperature sandwich voice coils.
This maintains rigidity and reliability while keeping weight low, resulting in superior sensitivity, dynamic range and power handling.
