DESCRIPTION
•Extraordinary impact
•High efficiency
•Extended response
The KF940 is a horn loaded subwoofer that provides output levels, frequency response extension, and efficiency completly out of proprotion to its size. Widely known as the SuperSub™, The KF940 is engineerd to be used in arrays of four or more to produce extremely high output sub bass response to the very bottom of the audible spectrum.
To provide the
