The Electrovoice SX500+ is a 400-watt, 15-inch two-way, biampable, high-efficiency, constant-directivity speaker system featuring a vented-horn woofer section.
The cabinet of the Electrovoice SX500+ is constructed of high-impact polypropylene structural foam, providing a stiff and extremely durable enclosure. It includes integral carrying handles and a stand socket for mounting on 1 3/8-inch stands such as the Electro-Voice 100BK. Rubber feet that are attached to the bottom of the cabinet and mating sockets that are molded into the top provide a means of stacking systems. The high-frequency section of the SX 500+ utilizes a molded-in 75 degrees x 60 degrees constant-directivity horn which is aimed downward by 10 degrees.
The SX500+'s high-frequency horn is driven by the DH2T one-inch throat, wide-bandwidth, titanium-diaphragm driver. A self-resetting high-frequency protection circuit, EV's PRO circuit, is included with the SX500+ to prevent against accidental overdrive and improve system reliability. The bass section of the SX500+ is a ventedhorn design using Thiele-Small parameters for solid performance to 43 Hz. This horn provides directivity control for the woofer section and matches the asymmetry of the high-frequency section. The 381-mm (15-in.) DL15Sx woofer used is a specially designed unit featuring an extended-length voice coil and high-temperature construction materials. The system combines professional- quality components, arranged in an unusually durable Thiele-Small-aligned vented enclosure.
