Product Characteristics
KS21 is a compact subwoofer designed to expand the bandwidth of the A15 system. The KS21 has a 21 "transducer with high offset and direct radiation in the bass reflection tuning box.
KS21 is paired with A15 to enhance low-frequency response and expand bandwidth to 29Hz and 31Hz, respectively. The KS21 is equipped with L-Vents layer ventilation vents, which can greatly reduce port turbulence noise at high levels and improve low-frequency efficiency. Compared with subwoofers of the same size, the combination of modern accessories and layer ventilation vents can greatly improve the transient sound pressure level of the KS21.
The frequency response of KS21 has been optimized and can be perfectly coupled with the A15 system. KS21 integrates a two point suspension system compatible with A15, which can be suspended or stacked for combined installation to form a full frequency line sound source. KS21 also integrates a threaded insert for rod mounted A15.
KS21 can be hung and stacked using specialized presets, with standard or heart-shaped orientation.
