Clair Brothers 8CX loudspeaker has beendesigned as a hi-fidelity, small-format pointsource speaker. The frequency response isfull range, 88Hz–20,000Hz, allowing for usefor speech and music reproduction. The 8CXfeatures the latest in neodymium coaxialtransducer technology with a pair of optionsin horizontal dispersion angles. A 100° conichorn is available and best suited for nearfield coverage applications and a 70° conicconstant directivity horn is also availablefor applications requiring tighter coverageand increased projection. The dispersionspecification is noted in the following uniqueproduct ID’s: 8CX-P-100, 8CX-P-70.
The 8CX features a SpeakON In/thruconnectors as well as a single two-positionterminal strip. An internal passive crossovernetwork provides third-order filtering allowingfor exceptionally clear output with remarkablecoherence through the crossover region. The8CX is well-suited for front fill applicationswith full PA systems just as it is equally wellequipped to stand alone as a main speaker in asmaller environment.

Mechanical & Accessories:

LIke its series companions, the 5CX and 5CB,the 8CX offers a seemingly unlimited numberof ways to rig and/or mount utilizing a familyof mounting accessories. The 8CX has (12)integral mounting points (M10 x 1.5 thread)and an integrated standard pole mount. Theaccessories include yoke mounting bracketsfor both vertical and horizontal mountingpositions as well as tilt adaptors to enable panand tilt in either configuration. The bracketsalso have a companion pole mount socket toallow unrestrained pan and tilt when used asa pole mount speaker. Additional accessoriesinclude: threaded stud plates, pipe clampmounts, chain rigging points, VESA tilt mountand array mode top-bar plates.
The 8CX is well-suited for down-firingapplications, such as large conventioncenters or high ceiling commercial spaces. Inparticular, the pair of mounting points availableon each panel of the cabinet are spacedat the same spacing as slots on standardUnistrut hardware, allowing for exceptionalcompatibility in commercial integrationprojects. Please contact Clair Brothers formore information regarding coverage areaplanning and simulation.


The loudspeaker system shall be a two-way passive, coaxial point source loudspeaker cabinet featuring a total of (2) drivers. The front ofthe enclosure shall be fitted with a perforated, powder coated steel grille backed with foam. The system shall have an amplitude responseof 100Hz to 18,000 Hz (+/−2 dB). The loudspeaker system shall be loaded with one woofer; this low frequency driver shall be 8” nominaldiameter with 2” voice coil diameter capable of handling 250W of power as per AES Standard. The high frequency section shall consist ofa 1.75” voice coil diameter compression driver mounted coaxially on a 100°H x 100°V (or 70°H x 70°V) horn. The high frequency horn shallprovide complete pattern control over the bandwidth. The high frequency horn shall be a constant directivity conic profile. The driver is capable ofhandling 50 watts (1 kHz to 10 kHz) of pink noise with a 6 dB crest factor for two hours (as per AES-1984 and ANSI S4.26-1984 standards). Theenclosure shall be trapezoidal in geometry, constructed with 15mm, 11-ply Baltic birch and covered with a durable black polyurea coating. Thedimensions shall be 13.50” high, 8.93” wide, and 8.67” deep. The 8CX enclosure shall incorporate twelve (12) integral rigging points, each withM10 x 1.5 thread for mounting bracket attachment. The passive system weight shall be 18 lbs (8.2kg). The loudspeaker system shall be the ClairBrothers 8CX-P-100 or 8CX-P-70 loudspeaker.
