Saurav---Good horn-driver combinations have very good frequency response and their rolloff is generally very smooth without "flareups", this due to the excellent damping that the column of air in the horn exerts on the diaphragm. Better I think than damping with notch filters as is common with direct-radiators. My Altec-JBL horn rig is +-3db from 25hz to 16khz on axis in my room, as shown on my RTA (not the most highly resolving of devices, it doesn't take that many "slices", but the trend is clear). One advantage is that the controlled dispersion of horns keeps sound from splattering all over the place, willy-nilly, doing God knows what to actual response at the listening point.
