1. Inc The Unity Series pushes the limits of modern state of the art sound reinforcement technology which features a radical new loudspeaker horn design arguably the first major evolution in horn technology in the last 60 years Ultra clear reproduction through the high mid band with extremely linear frequency response has been achieved using the patented Unity horn technology licensed from Sound Physics Labs Inc Unity horn tech nology combines a single 1 throat with a 1 75 diaphragm high frequency compression driver alongside three 5 ceramic magnet midrange drivers on a single highly efficient conical horn This combines high and mid frequency energy in a single 60 x 60 conical horn that produces frequencies from 300Hz to 20kHz Patent holder Tom Danley explains it this way With a conical horn one sees that at the compression driver exit the expan sion rate is very rapid at high frequency cutoff and since the expansion rate acts as a high pass filter the low frequency energy does not couple to the mouth Move a few inches toward the mouth and one finds the expansion rate is much slower and suitable for low midrange if only that was where the driver was All one has to do is obtain a mid driver suitable for efficient horn loading in that frequency band and find the point in the flare where the expansion rate is suitable for that frequency range and couple the sound in at that point Because the compression driver and each mid2. driver are less than 1 4 wavelength apart their output combines fully and coherently something which cannot happen if the driver were further than about 1 3 wavelength apart U S Patent 6 411 718 B1
