COMPACT MONITOR SYSTEMS
SOUND PRESSURE
is a new
line of professional speakers designed by LEM to be used as
portable P.A. system
, for
live and
studio monitoring
and for
instal-
lations
in a variety of different
situations.
The
SOUND PRESSURE
speakers are available in three models,
SP LIVE, SP MEDIA
and
SP
SUB
and are all equipped with a
powerful internal amplifier.
SP
LIVE
and
SP MEDIA
are also
available in the passive version.
The speaker’s cabinets are made
of polypropylene reinforced with
mineral fibres, a type of plastic material that is exceptionally sturdy
and light. This material allowed us
to obtain an accurate and elegant
design, which makes the SP
speakers an ideal choice for particular settings where a perfect integration with the environment is
required. The cabinets are also
equipped with a special fixing sys-
tem which, thanks to seven dedicated accessories,
make it possible to install them practically
everywhere and to
combine them together, so as to obtain
extremely versatile setups.
The
SOUND PRES-
SURE
series utilizes
professional speakers made to LEM
specs, and is always
up to give a linear fre-
quency response even at maximum power, without distortion
and with excellent sound quality.
SP LIVE ACTIVE
and
SP ME-
DIA ACTIVE
incorporate a
90W
internal amplifier. Used individually or in combination with the
SP SUB ACTIVE
, which is
equipped with a
350W
amplifier,
they can provide an amplification
system with an exceptional
power/dimension ratio. All the
amplifiers are equipped with
anti-
clipping circuit
and with
highly
professional connection panels
.
SP LIVE
The
6½” wide-range speaker
comes with double cone and with
a 90W handling power, allowing
very high efficiency
(up to 111dB
MAX SPL), particularly in the mid
range, which makes this speaker
particularly suited for LIVE performances, monitoring of voice and
musical instruments and amplification in public spaces, malls, conference halls, hotels, restaurants,
etc.
SP MEDIA
The
two-way system
,
with silken dome
tweeter mounted on
elliptical horn
(EWT™,
LEM patent) and 6½”
woofer in acoustic
suspension, guarantees a
high sound
quality
and a
wide fre-
quency response
(from 70 Hz to 20
