S-40

Compact Monitor

Description

The Electro-Voice S-40 is an extremely com-

pact high- performance monitor loudspeaker

system. It is ideally suited for indoor or out-

door applications requiring high-quality

sound reproduction. As a near-field moni-

tor in control rooms or broadcast studios, or

as a foreground or background loudspeaker

in restaurants and clubs, the S-40 is the

choice of professional users. Its high power

handling also makes the S-40 an ideal loud-

speaker for nearfield monitoring in live per-

formance situations. Threaded inserts in the

cabinet in combination with the optional

mounting hardware provide a flexible

mounting system for virtually any applica-

tion.

The low-frequency section is a 5-1/4" di-

rect-radiating woofer with a polypropylene

cone installed in an optimally vented high-

impact polystyrene enclosure. This combi-

nation produces an exceptionally extended

bass response with relatively high efficiency

for an extremely small enclosure. The use

of plastic materials for the enclosure and cone

allow the loudspeaker system to be used in

high-humidity environments.

The high-frequency section is a 1-in. direct-

radiating soft dome tweeter. The tweeter is

ferro-fluid cooled and uses flexible tinsel

lead wires to prevent thermal or mechanical

failure. These features in addition to the large

magnetic system make this the most rugged

tweeter ever used in a system this size.

These high quality components will provide

years of listening pleasure when driven at

reasonable levels. However, sometimes

loudspeakers are accidently over-driven,

causing the drive units to fail. To prevent

against this, EV engineers have incorporated

independent woofer and tweeter protection

circuits in the S-40. These circuits will au-

tomatically reduce the power being delivered

to the drivers if their threshold is exceeded,

greatly reducing the possibility of driver fail-

ure.

Both drivers feature low-flux-leakage de-

signs enabling the speaker to be used in close

proximity to video monitors. For very criti-

cal video monitoring applications, a mini-

mum distance of four inches from the edge

of the loudspeaker to the edge of the CRT is

recommended.

Frequency Response

The combination of 5-1/4" woofer, 1-inch

tweeter and optimized crossover result in the

wide and smooth frequency response shown

in Figure 1. This response was measured at

1 meter, using a 2 Volt (1 watt) input in an

anechoic chamber. The response is 1/3-oc-

tave averaged and no external equalization

was used.

Directivity

The polar response of the S-40 speaker sys-

tem at selected 1/3-octave bandwidths is

shown in Figure 4. These polar responses

were measured in an anechoic environment

at 10 feet using 1/3-octave pink noise inputs.

The frequencies selected are fully represen-

tative of the polar response of the system.

Beamwidth of the system utilizing the com-

plete 1/3-octave polar data is shown in Fig-

ure 2. Rq (Q) and directivity index (Di) are

plotted in Figure 3.

Power Handling Capacity

To our knowledge, Electro-Voice was the

first U.S. manufacturer to develop and pub-

lish a power test closely related to real-life

conditions. First, we use a random noise

input signal because it contains many fre-

quencies simultaneously, just like real voice

or instrument program. Second, our signal

contains more energy at extremely high and
