About the 21″
The Tekton Design 21″ Sub is a passive subwoofer designed for extreme home theater and high-fidelity music applications. It utilizes a premium B&C Italian 21-inch transducer with 60 mm peak-to-peak excursion, delivering profound bass with high efficiency around 95 dB. The enclosure is compact for its driver size at approximately 20 inches deep, making it relatively easy to integrate into rooms. It requires a powerful external amplifier capable of at least 2000 watts RMS with a subsonic filter around 25 Hz recommended. Crossover is typically set at 60 Hz. A 500W plate amplifier option is available separately. Still actively sold on the official site.
