Description

The Electro-Voice Sx500PI+ is a weather-resis-

tant version of the popular Sx500+ loudspeaker.

It is a 400-watt, 15-inch two-way, biampable,

high-efficiency, constant-directivity speaker

system featuring a vented-horn woofer section.

The weather-resistant features are the specially

treated woofer, the DL15Sx-W, and the full-face

stainless-steel grille backed with both foam and

a polyester mesh water shield. Additionally, two

port plugs are included for the customer to in-

stall when increased weather resistance is

needed. Through extensive use of computer-

aided design and modeling, Electro-Voice en-

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

fessional loudspeaker system for permanent in-

stallations where weather resistance is needed.

The high-frequency section of the Sx500PI+ uti-

lizes a molded-in 75° x 60° constant-directivity

horn which is aimed downward by 10°. This

unique pattern contributes to high intelligibility

and aims the speaker's output where it is most

useful. Vocals sound natural yet “cut through”

in reverberant, noisy rooms. In addition, the cov-

erage pattern is unusually uniform over its range

of operation. The horn’s unique, VariPath

throat geometry helps direct driver output to the

corners of the room, to points of coverage not

described in the usual specifications of horizon-

tal and vertical coverage angles, and to parts of

the audience that typically do not receive the

strongest coverage.

One of the many other unique features of the

Sx500PI+ is the cabinet. Constructed of high-

impact polypropylene structural foam, it pro-

vides a stiff and extremely durable enclosure.

The cabinet includes integral carrying handles

and a stand socket for mounting on 1

-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 shaped

plastic cabinet, in combination with the uniform,

75° x 60° directivity characteristics, make the

Sx500PI+ ideal for use alone or in arrays.

The Sx500PI+’s high-frequency horn is driven

by the DH2T one-inch throat, wide-bandwidth,

titanium-diaphragm driver. This driver uses a

unique, convex-drive Time Path

™

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

exclusive Resonant Drive™ Technology. This

increases and smooths the high-frequency re-

sponse and reduces the amount of internal equal-

ization required for flat frequency response,

which extends to 20,000 Hz.

A self-resetting high-frequency protection cir-

cuit, EV’s PRO™ circuit, is included with the

Sx500PI+ to prevent against accidental over-

drive and improve system reliability. If the in-

put power to the high-frequency driver exceeds

the nominal rating, the protection circuit is acti-

vated 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 re-

duced to a safe level.

The bass section of the Sx500+ is a vented-horn

design using Thiele-Small parameters for solid

performance to 45 Hz. This horn provides di-

rectivity control for the woofer section and

matches the asymmetry of the high-frequency

section. The 381-mm (15-in.) DL15Sx-W

weather-resistant woofer used is a specially de-

signed unit featuring an extended-length voice

coil and high-temperature construction materi-

als. The system combines professional-quality

components, arranged in an unusually durable

Thiele-Small-aligned vented enclosure. The re-

sult is clear and articulate, high-quality sound.

Ring-Mode Decoupling (RMD

)

Technology

The Sx500PI+ controls both acoustical and me-

chanical ring modes to provide dramatically

in-

creased intelligibility, using techniques 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. The most obvious imple-

mentation of RMD™ in the Sx500PI+ is the

foam attached to the back of the woofer grille.
