PRODUCT INFORMATION
The MC4953B full-range screen channel loudspeaker system brings
3-way design to the largest cinema exhibition spaces. Its passive
mid/high biamplified design lets it replace existing biamped two-
way systems without requiring new electronic crossovers or ampli-
fiers. (Electronic crossovers settings may need to be adjusted.)
Three-way design dramatically advances cinema audio quality by
improving the naturalness and intelligibility of dialog, eliminating
distortion from excessive driver excursion and extending pattern
control into the lower octaves.
The MC4953B combines many of EAW’s breakthrough technologies
including the mathematically correct mid/bass horn with phase/
displacement plug, "push/pull" low frequency technology and the
"short-throat" high frequency horn.
The three component system includes 2x 15-in woofers in a "push/
pull" configuration, 2x horn-loaded 10-in mid frequency cones and
a horn-loaded 2-in exit high frequency compression driver.
The "push/pull" configuration of the LF section reduces mechani-
cally induced distortion at high output levels. To move air "forward"
(away from the enclosure) half of the woofers push while the other
half pull.
The MC4953B’s mathematically-correct MF horn with phase plug
drastically reduces the horn-throat cancellation distortion that
degrades the naturalness and intelligibility of dialog. By dividing
the mid/high material between two horn-loaded subsystems, pat-
tern control over the entire frequency range is enhanced.
The MC4953B requires the use of an external active electronic
crossover between the LF section and mid/high section which
includes an internal passive crossover/filter network. EAW's com-
plex, computer-designed passive filter networks are tightly aligned
to the loudspeakers they control and go beyond merely dividing the
signal, performing critical equalization functions.
The HF element - an HK294 HF system - features a 2-in exit
compression driver loaded with a short-throat 90° x 40° HF horn
ensuring even distribution of HF information throughout the audi-
torium.
Input connectors for the LF and MF sections are two-terminal barrier
strips. A "jumper cable" is included to continue the signal chain to
the HF section. Bind posts for the HF section are located directly on
the compression driver. The input panels are located on the sides of
the enclosures for convenient access in cramped installation areas.
All external components feature a “dead” flat black finish to
eliminate the reflection of light through perforated cinema screens.
