CAUTION!
C7-TOP
The C7-TOP is a two way horn loaded loudspeaker which provides
full range coverage at very high SPLs. The constant directivity
design of the coaxial horns used in the C7-TOP helps maintain the
75° x 40° dispersion down to 600Hz. Two passively coupled drivers
are used - a 15 low/mid driver back loaded by a vented
enclosure, and a 1.5 exit HF compression driver.
The C7-TOP cabinet is constructed from marine plywood, fitted
with steel handles, MAN CF4 stud plate rigging points and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill, covered with a replaceable
acoustically transparent foam and fitted with catches to the top
and bottom for securing an optional transport lid E7908. Mounted
on the rear panel are ratchet strap guide plates (kelping bars), four
M10 threaded inserts for attaching installation hardware, two
Speakon NL4 or EP-5 connectors wired in parallel and four heavy
duty wheels.
As the C7-TOP maintains its high efficiency from 18 kHz down to
68 Hz, subwoofers are not needed for applications which do not
require very low frequencies.
When high level bass reproduction is desired, then the C7-TOP can
be supplemented with the C7-SUB or B2-SUB systems. In larger
systems the C7-TOP can also be operated with the C4-SUB and B2
subwoofer combination.
High output, wide horizontal and narrow vertical dispersion down
to the low/mid range means that a simple set up using a pair of
C7-TOP cabinets, one per side, can deliver smooth wide area
coverage across the near field to a distance of 30 m (100 ft).
Within a larger set up C7-TOP cabinets are ideal as frontfill,
nearfill or delay systems for C4 arrays.
The C7-TOP is compatible with the C4 System - both loudspeaker
systems share similar phase responses and cabinet dimensions
allowing the straightforward construction of stacked or flown
mixed cabinet arrays.
Placing a pair of C7-TOP cabinets with their angled rear side
panels together sets them 50° apart to give a combined horizontal
coverage of 130°. Similarly a C7-TOP deployed with a C4-TOP
sets the cabinets 40° apart to give a combined horizontal coverage
of 100°.
Only operate C7-TOP loudspeakers with a d&b P1200A mainframe
fitted with C7-TOP controller modules, otherwise there is a risk of
damaging the loudspeaker components.
