User manual YORKVILLE TX5P

[. . . ] The 1500-watt integrated power amplifier takes full advantage of the cabinet's horn-loaded design and single 15-inch long excursion driver to deliver enough bottom end support for virtually any PA application. [. . . ] The unmatched performance of the UCS1P is the direct result of outstanding cabinet design combined with innovative integrated electronics designed to maximize the UCS1P's output. The UCS1P can be connected to any line or speaker level source via the XLR / TRS Combi-jack input. Built-in crossover circuitry means the UCS1P can be added to any system without complicated external crossovers being required. Multiple UCS1P's can be integrated into any setup using the XLR or 1/4" TRS balanced thru put on each power module. "With a conical horn, one sees that at the compression driver exit, the expansion 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 mid 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.
