Architects’ and Engineers’ Specications
The two-way loudspeaker system shall be self-contained
and consist of the following components: (1) a low-frequency
driver; (2) a constant directivity horn driven by a dome tweet-
er driver; (3) a two-way crossover network; (4) a vented enclo-
sure.
The low-frequency transducer shall be a cone type loud-
speaker having a carbon ber cone with a diameter of at
least 5 inches (130mm). The cone shall be tted with a high
compliance foam surround and treated to resist moisture. It
shall have a voice coil that is at least 1 inch in diameter and
present a nominal 8-ohm load impedance to the crossover
network.
The high-frequency section shall consist of a constant
directivity horn driven by a soft dome tweeter having a diam-
eter of at least 0.75 inches (19mm). Its voice coil shall be
treated with Ferrouid
®
to aid in cooling. It shall present a
nominal 8-ohm load impedance to the crossover network.
The
constant directivity horn shall have an integral phase
correcting mechanical equalizer.
The system shall be crossed over by an internal, high-
level, passive network having a response of 12 dB/octave
and equalization for the constant directivity horn. The nomi-
nal crossover frequency shall be 2.5kHz. The low-pass sec-
tion of the network shall have minimum inductance in series
with the low-frequency driver. A dynamic high-frequency pro-
tection circuit based on a low-value, low-mass lament resis-
tor shall limit the current available to the high-frequency driv-
er. The crossover network shall present a nominal 4-ohm load
impedance to the power amplier.
The enclosure shall be a vented design. It shall be con-
structed using high density polystyrene and nished with
black (or white), scratch resistant paint. It shall be trapezoidal
in shape with 45° angled sides. A full size, detachable, perfo-
rated steel grille, nished in black (or white) scratch resistant
paint shall be provided. At least 4 reinforced threaded metal
sockets (3/8" and M6) for attaching optional mounting hard-
ware shall be provided. The overall dimensions of the enclo-
sure shall not exceed (HxWxD) 10.32" x 7.17" x 6.57"
(262mm x 182mm x 167mm). The total weight of the loud-
speaker shall not exceed 8.6 lbs. (3.9 kg). Connections to the
loudspeaker shall be two gold-plated banana jacks.
The loudspeaker system shall have an overall frequency
response of at least 65Hz–20kHz when measured to –10 dB
and at least 100Hz–19kHz when measured to –3 dB. It shall
have a nominal average coverage pattern of at least 105°
horizontal by 105° vertical to –6 dB when measured between
800Hz and 16kHz. Calculated 1W/1m sensitivity shall be at
least 87 dB when measured in the far eld between 300Hz
and 3kHz. Maximum SPL shall be at least 112 dB at 1m.
The loudspeaker shall be rated for continuous operation at
175W IEC with 700W peaks.
The two-way loudspeaker system shall be a model MR5S
(MR5SW - white) manufactured by Mackie Industrial.
