ElectroVoice Sx500+ 2-way Loudspeaker, 400W 15" NIB

The Electro-Voice Sx500+ is a 400-watt, 15-inch two-way, biampable, high-efficiency, constant-directivity speaker system featuring a vented-horn woofer section. Through extensive use of computer-aided design and modeling, Electro-Voice engineers have developed a state-of-the-art professional loudspeaker system.

Its cabinet 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 Sx500+ utilizes a molded-in 75° x 60° constant-directivity horn which is aimed downward by 10°. 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. The result is clear and articulate, high-quality sound.
