Arena 215CX is a full-range, two-and-a-half-way bass reflex enclosure equipped with a modern premium custom coaxial driver. Arena 215CX enclosures integrate perfectly into stadium installations with Stadia Series units, providing seamless audio throughout areas not covered by the main system. This loudspeaker also provides extremely effective multi-purpose solutions in any application where high quality audio needs to be distributed around outdoor areas, such as theme parks, leisure facilities, tourist attractions and public spaces.

Outline’s high quality coaxial driver gives excellent sonic performance, increased timbre quality and high power handling characteristics. It is loaded by a proprietary moulded waveguide, which is coaxial to the 15” mid-woofer and provides low-pass acoustical loading on the woofer, increasing the efficiency in its usable bandwidth. Uniquely configured as a ‘two-and-a-half’ way system both electrically and acoustically, Arena 215CX delivers audio performance approaching a three-way design with extended low frequency, outstanding sound quality and remarkable SPL. Thanks to Outline’s exclusive internal crossover designs, the enclosure can be driven by a single channel of amplification, while it is also possible to use two amplifier channels to drive the low and coaxial sections separately.
