The three horns integral to the KF-550 were developed by
Kenton Forsythe and conform precisely to the mathematical
models by using a proprietary, polyurethane foam,
reinforced hardwood construction technique. This results in
exceptionally smooth air loaded impedance characteristics
for a smooth frequency response and efficiency unmatched
by other. high fidelity systems.
