INTRODUCING THE MILO 60

A variation on the popular MILO high-power curvilinear

loudspeaker, the MILO 60 high-power narrow coverage

curvilinear array loudspeaker excels where controlled narrow

horizontal coverage is needed. The self-powered MILO 60

(Figure 1) is a compact, lightweight four-way system that

provides 60 degrees of horizontal coverage, and vertical

coverage matching the original MILO (nominally 10 degrees

in the high-frequency and very-high-frequency sections;

vertical coverage across all frequency bands within a line ar

ray varies, depending on the length and conﬁguration of the

array). The coverage pattern is optimized for applications re

quiring tight horizontal coverage, such as at the top in mixed

arrays with standard MILO line array loudspeaker systems,

or for sideﬁll systems to extend horizontal coverage.

loudspeaker

The MILO 60 loudspeaker produces a peak output of 140

dB SPL with exceptionally ﬂat phase and frequency re

sponse. Its wide operating frequency range (60 Hz to 18

kHz) is complemented by extended high-frequency head

room and a dedicated very-high-frequency section (4.2 kHz

to 18 kHz) that renders delicate transient information with

detailed resolution through its coverage pattern. The driver

complement is identical to that of MILO, with the compres

sion drivers in the high- and very-high-frequency sections

going through patented REM™ ribbon emulation manifolds

into custom 60-degree constant-directivity horns. Control

electronics are designed to maintain ﬂat frequency and

phase response throughout the loudspeaker’s coverage

pattern. The MILO 60 loudspeaker’s acoustical character

istics are designed to facilitate seamless integration when

used with other MILO curvilinear array elements.

As with all MILO loudspeakers, the MILO 60 comes stan-

dard with integrated ampliﬁcation, RMS™ remote moni

toring system, TruPower

limiting system, and AlignaLink

hardware for use with the MILO QuickFly

rigging hardware.

MILO 60 DRIVER INTERCONNECTIONS

The MILO 60 uses the same 4-channel ampliﬁer as the

standard MILO loudspeaker, and the low-frequency control

card is the same. The upper control card for the high-fre

quency and very-high-frequency sections is speciﬁc to

the MILO 60. Each front 4-ohm, 12-inch, low-frequency

cone driver is powered by one 1125-watt channel of the

HP-4/MILO ampliﬁer. The single 4-inch diaphragm, 8-ohm

high-frequency compression driver is powered by a single

560-watt channel and the three 2-inch diaphragm, 12-ohm

very-high-frequency compression drivers share the fourth

1125-watt channel. The following diagram shows how the

drivers are connected to the ampliﬁer.
