Sx300
12-inch, 300 Watt,
Two-Way Compact
Speaker System
General Description:
The Electro-Voice ® Sx300 is a 300-watt, 12-inch two-way,
high-efficiency, constant-directivity compact speaker system
with Ring-Mode Decoupling (RMD
TM
). Through the extensive
use of computer-aided design and modeling, Electro-Voice
engineers have developed a state-of-the-art professional
loudspeaker system. The high-frequency section of the Sx300
utilizes a molded-in, 65° x 65° constant-directivity horn. This
unique pattern contributes to high intelligibility, vocals sound
natural yet “cut through” in reverberant, noisy rooms. In addition,
the coverage pattern is unusually uniform over its range of
operation. Sound quality off axis is very well maintained, even
at 45° off axis (a 90° total coverage angle), beyond the rated
coverage angle. The horn’s unique, Varipath
TM
throat geometry
helps direct driver output to the corners of the room, this helps
cover areas of the audience that typically do not recieve good
coverage. High-impact polypropylene structural foam provides
a stiff and extremely durable lightweight enclosure. Molded
into the cabinet are an integral carrying handle and a stand
socket for mounting on 1-3/8-inch stands such as the Electro-
Voice 100BK. Rubber feet that are attatched to the bottom of
the cabinet and mating sockets that are molded into the top
provide a means of stacking systems. The trapezoidal-shaped
cabinet, in combination with the uniform, 65° x 65° directivity
characteristics, make the Sx300 ideal for use alone or in arrays.
