Description

The Sx300PI and Sx300PIX are continua-

tions of the popular the Sx-series offering

the added value of weather-resistant cabi-

nets. The Electro-Voice Sx300PI is a 300-watt,

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

directivity speaker system for permanent in-

stallation. Through the extensive use of

computer-aided design and modeling,

Electro-Voice engineers have developed

a state-of-the-art professional loudspeaker

system for permanent installation where

weather resistance is needed. The

Sx300PIX is the same as the Sx300PI with

the addition of an AT100 transformer.

The high-frequency section of the Sx300PI

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

rectivity horn. This unique pattern contrib-

utes to high intelligibility. Vocals sound

natural, yet “cut through” in reverberant,

noisy rooms. In addition, the coverage pat-

tern is unusually uniform over its range of

operation. Sound quality off axis is very

consistent, 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 cover-

age 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

Sx300PI is the cabinet. Constructed of high-

impact polypropylene structural foam, it pro-

vides a stiff and extremely durable enclosure.

Molded into the cabinet are an integral carry-

ing handle and a stand socket for mounting

on 13/8-inch stands such as the Electro-Voice

100BK. Rubber feet attached to the bottom of

the cabinet and mating sockets molded into

the top provide a means of stacking systems.

The trapezoidal-shaped cabinet in combina-

tion with the uniform, 65° x 65° directivity

characteristics, make the Sx300PI ideal for use

alone or in arrays.

The Sx300PI’s high-frequency horn is driven

by the Electro-Voice 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 extended

high-frequency performance. The voice coil

is coupled to the diaphragm with EV’s exclu-

sive Resonant DriveTM technology. This in-

creases and smooths the high-frequency re-

sponse and reduces the amount of internal

equalization required for flat frequency re-

sponse. Driver output extends to 25,000 Hz.

A self-resetting, high-frequency protection cir-

cuit, EV’s PROTM circuit, is included with the

Sx300PI to prevent accidental overdrive and

improve system reliability. If the input power

to the high-frequency driver exceeds the nomi-

nal rating, the protection circuit is activated

and reduces the power delivered to the driver

by 6 dB. The system will remain in this mode

of operation until the input power is reduced

to a safe level.

The bass section of the Sx300PI is designed

using Thiele-Small parameters for efficient

performance to below 80 Hz. The woofer is a

DL12Sx 12-inch unit featuring beryllium cop-

per lead wires, a low-mass, edge-wound voice

coil and high-temperature materials. The part

of the magnetic structure adjacent to the coil

is insulated using the exclusive EV PROTEF

process (U.S. Patent #4,547,632). The sys-

tem combines professional-quality compo-

nents, arranged in a time-coherent vertical ar-

ray, with an unusually durable Thiele-Small-

aligned vented enclosure. The result is clear

and articulate, high-quality sound.

Ring-Mode Decoupling (RMD

TM)

The Sx300PI controls both acoustical and

mechanical ring modes to provide dramati-

cally increased intelligibility, using tech-

niques learned from the development of the

Electro-Voice X-array™ concert speakers.

There is much less coloration of the sound

from resonating sources, leaving only the

intended sound to be heard by the audience.
