Bent bass horn subwoofer. (2) 12-in. heavy duty woofers &plusm;3 dB 24 - 300 Hz. Peak output: 145 dB SPL. For portable use only.
The KF940 portable horn-loaded subwoofer system -- otherwise known as the Super-Sub -- has created a new level of sub bass performance by loading two specially designed 12-in. woofers with a horn with an exponentially expanding throat that is over 13 ft long. Great care has been taken to create woofer cones that could withstand the force of being loaded with such a large horn. As an impedance matching device -- the horn brings the 1 watt @ 1 meter sensitivity of the system at 100 Hz to 113 dB SPL. The KF940s horn uses a construction technique that allows us to create horns with the necessary complex expansion rates. The complex flares are constructed from a 3 mm veneer of birch plywood that is fit into slots cut by our computer-numeric-con
trolled router. The birch veneer is then backed with a proprietary anti-resonance high-damping polyurethane foam -- making the horn acoustically opaque.
