Clair Brothers 15CX-P loudspeaker has been designed
as an ultimate hi-fidelity, large-format point source
speaker. The frequency response is full range,
38Hz–16,000Hz, allowing for use for speech and
music reproduction. A stand-out feature of 15CX-P
is its innovative horn technology. A coaxial horn
arrangement provides conic constant directivity
pattern control to both the 15” woofer as well as the
3” voice coil diameter compression driver.
The 15CX-P also features a unique combination of
two horns. One horn responsible for directing low
frequencies is a precision-machined solid birch
plywood horn, measuring 35.5” at the mouth. The
high frequency horn is comprised of three sections.
The first section is a solid exponential throat followed
by a conic constant directivity geometry made
of heavy gauge perforated steel. The perforation
patterns are geometrically optimized to allow proper
crossover region behavior over the 60° polar coverage
area between the upper midrange frequencies of the
woofer with the compression driver. This technology
solves the common problem of horn shadowing
with prior coaxial designs. The high frequency horn
seamlessly joins with the low frequency horn as it
extends toward the mouth.

The 15CX-P coaxial product family consists of two
versions, 15CX-P and 15CX-CP. They are acoustically
similar but mechanically different.
The 15CX-P (pictured) is designed with a curved
perforated steel grille and is well suited for outdoor
or exposed installations. 15CX-P features versatile
mounting options from 20 integrated points.
The other model, 15CX-CP (not pictured), is intended
for use in commercial installation applications where
an exterior grille is unnecessary as it may be installed
above finished ceilings. 15CX-CP is outfitted with two
attachment points for an optional mounting bracket.
