EAW MR102 User manual
Features:
*Smooth response with high output capabilities over the critical
vocal mid band, where most existing horn loaded systems are
weakest
*True Exponential Horn flare for Maximum efficiency and
bandwidth over the operating range.
*EAW's world-famous quality construction using crossgrained
laminated birch and urethane foam reinforcing for resonance-free
performance at high sound pressure levels.
Design:
The MR- 102 is designed to answer the need for low
distortion, high output performance in the critical vocal mid band.
This range, from 400 Hz to 1,500 Hz, typically has the lowest
headroom in horn loaded systems. Use of MR102's from 200 Hz
to 1200 Hz will enable much lower distortion and an
improvement of from 3 to 6 dB output in most typical horn
loaded systems. Additionally, the use of mid-bass horn will take
considerable stress off the compression driver by raising the
crossover frequency. To understand this, if you raise the
crossover one octave (i.e. from 600 Hz to 1200 Hz) you require
the compression driver diaphragm to move 1/4 as far to provide
the same level. This means that for most applications the need to
constantly replace diaphragms will be eliminated. The throat
distortion induced in the horn will be reduced dramatically as well.
Discription:
The MR- 102 is an exponential horn with a 175 Hz
cut-off frequency designed for critical lower midrange use in large
sound reinforcement systems. The MR- 102 makes use of a
center displacement plug to maintain an accurate exponential
expansion down into the throat region. This plug allows for a
proper throat cross section and expansion to maintain flat
response over the full range of the horn. Additionally this type of
design limits throat size offering exceptionally high efficiency and
blocks high frequency spikes from the driver's dust cap above the
operating range, thus preventing time/frequency related problems
around the crossover region. The high-frequency response is
dependent on the driver used with a maximum limit of 1600 Hz
(with and EAW LF-300-R driver response is smooth to 1200 Hz).
The MR-102 comes ready for road use with
conveniences such as recessed bar handles, steel corners, a
perforated steel speaker grill, and Tee-nuts for mounting wh

designed to withstand the rigours of day in-day out touring u

ruggedness of the MR- 102.
