Description

The Electro-Voice Sx300is a 300-watt,

12-inch two-way, high-efficiency, con-

stant-directivity compact speaker system

with Ring-Mode Decoupling (RMDTM).

Through the extensive use of computer-aided

design and modeling, Electro-Voice engi-

neers have developed a state-of-the-art pro-

fessional loudspeaker system.

The high-frequency section of the Sx300

utilizes a molded-in, 65° x 65° constant-di-

rectivity horn. This unique pattern contrib-

utes to high intelligibility. Vocals sound natu-

ral yet “cut through” in reverberant, noisy

rooms. In addition, the coverage pattern is

unusually uniform over its range of opera-

tion. Sound quality off axis is very well

maintained, even at 45° off axis (a 90° total

coverage angle), well beyond the rated cov-

erage angle. The horn’s unique, VaripathTM

throat geometry helps direct driver output to

the corners of the room, points of coverage

not described in the usual specifications of

horizontal and vertical coverage angles, and

parts of the audience that typically do not

receive the strongest coverage.

One of the many other unique features of

the Sx300 is the cabinet. Constructed of high-

impact polypropylene structural foam, it pro-

vides a stiff and extremely durable enclo-

sure. 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

attached to the bottom of the cabinet and mat-

ing sockets that are molded into the top pro-

vide a means of stacking systems. The trap-

ezoidal-shaped cabinet, in combination with

the uniform, 65° x 65° directivity character-

istics, make the Sx300 ideal for use alone or

in arrays.

In situations requiring additional bass out-

put, the Sx300 can be used in combination

with the Electro-Voice Xp200A system con-

troller. The Xp200A includes a low-fre-

quency enhancement circuit that is tailored

to match the low-frequency characteristics

of the Sx300. Up to 12 dB of additional bass

output can be obtained from the system when

used with the Xp200A system controller. The

amount of low-frequency enhancement can

be adjusted to suit the user’s personal pref-

erence.

For the most demanding situations, two bass-

module models are available to complement the

Sx300:the Electro-Voice Sb121 nonpowered

bass module and the Electro-Voice Sb121a pow-

ered bass module. Both bass modules were de-

signed to be used with the Sx300and are

constructed in similar structural foam enclo-

sures. The Sb121a includes a 300-watt power

amplifier that is built into the speaker cabi-

net. The Xp200A system controller provides

a subwoofer output that is a crossed-over

sum of the left and right channels.

The Sx300’s high-frequency horn is driven

by the DH2010A one-inch-throat, wide-

bandwidth, titanium-diaphragm driver. The

DH2010A uses a unique, convex-drive

Time PathTM phasing plug structure (U.S.

Patent #4,525,604) for smooth and ex-

tended high-frequency performance. The

voice coil is coupled to the diaphragm with

EV’s exclusive Resonant DriveTMtechnol-

ogy. This increases and smooths the high-

frequency response and reduces the amount

of internal equalization required for flat fre-

quency response. Driver output extends to

25,000 Hz. A self-resetting high-frequency

protection circuit, EV’s PROTMcircuit, is

included with the Sx300to prevent against

accidental overdrive and improve system

reliability. If the input power to the high-fre-

quency driver exceeds the nominal rating,

the protection circuit is activated and reduces
