P av y’s r volutionary n w Quadratic
Throat Wav guid s. In th ILS 1594H
unit, th wav guid is rotat d to provid
a corr sponding b amwidth which may
b mploy d in low c iling typ
applications. Both v rsions of th ILS
1594 hav a full rang s nsitivity of 95
dB SPL – (1 Watt/1 m t r) and a
maximum output of 130 dB at 1 m t r
(full rang ).
Th P av y ILS 1594 is a high

us in d manding sound r inforc m nt
applications. Th robust construction of
th ILS 1594 provid s pow r handling

Frequency Response
This m asur m nt is us ful in
d t rmining how accurat ly a giv n
unit r produc s an input signal. Th
fr qu ncy r spons of th ILS 1594 is
m asur d at a distanc of 1 m t r
using a 1 Watt (into th nominal
imp danc ) sw pt-sin input signal.
As shown in figur 1, th s l ct d
driv rs in th ILS 1594 combin to
giv a smooth fr qu ncy r spons
from 52 Hz - 20 kHz.
Directivity

unit. Th s param t rs provid insight
for prop r plac m nt and installation
in th chos n nvironm nt. Th
bl nding of th compon nts of th ILS
1594 xhibit a d sirabl b amwidth
and dir ctivity (figur 3 & 4) suitabl
for sound r inforc m nt applications.
Power Handling
Th r ar many diff r nt approach s
to pow r handling ratings. P av y
rat s this loudsp ak r syst m's pow r
handling using a full-rang form of th
AES Standard 2-1984. Using audio
band 20 Hz to 20 kHz pink nois with
p aks of four tim s th RMS l v l,
this str nuous t st signal assur s th
us r that v ry portion of this syst m
can withstand today's high t chnology
music. This rating is conting nt upon
having a minimum of 3 dB of amplifi r
h adroom availabl .
Harmonic Distortion
S cond and third harmonic distortions

& 6 for two pow r l v ls. (T n p rc nt
(10%) of rat d input pow r and ith r
on p rc nt (1%) of rat d input pow r
or on Watt, which v r is gr at r)
Distortion is r ad from th graph as
th diff r nc b tw n th
fundam ntal signal (fr qu ncy

As an xampl , a distortion curv that
is down 40 dB from th fundam ntal
is quival nt to 1% distortion.
