Mid-High to Very-High Frequencies: Greater Output, Lower Distortion
In their designs for line arrays, most manufacturers recognize that
the high frequency vertical pattern of each loudspeaker must be tightly
controlled to minimize interference between units in the array. But
some common solutions, such as using long waveguides to collimate compression
driver output, gain the necessary control only at the cost of increased
distortion.
By contrast, MILO employs two patented REM ribbon emulation manifolds
for the separate mid-high and very-high frequency sections, each coupled
to individual constant-directivity horns. REM is a proprietary coupling
device that introduces driver output to the horn throat across a very
short path (3 inches for the mid-high section and 1.5 inches for the
very-high section), effectively controlling the output but with dramatically
reduced distortion in comparison to other techniques.

Because high frequency drivers are critical to overall
system performance, all compression drivers in MILO are designed
and manufactured in house by Meyer Sound. Rigid manufacturing
tolerances and stringent quality control ensure stable, consistent
response characteristics.

MILO’s mid-high section (560 Hz - 4.2 kHz) employs a single
1.5-inch exit, 4-inch diaphragm compression driver powered by a dedicated
560-watt amplifier channel. The very-high frequency section utilizes
three 0.75-inch exit, 2-inch diaphragm compression drivers to produce
extraordinary power and clarity, and also extend operating frequency
range up to 18 kHz. To provide maximum system headroom, power for the
very-high frequency section is supplied by a dedicated 1125-watt amplifier
channel.
Two patented REM ribbon emulation manifolds
couple the four Meyer Sound compression drivers to the constant
directivity horns. REM controls driver output and introduces
it to the horn throats within the shortest possible path length,
and consequently produces far less distortion than devices
in other line arrays that employ longer paths.
