The STADIA100 LA range comprises of three loudspeaker modules of very similar dimensions but identical horizontal directivity (100), and which offer a choice of 10, 20, or 30 dispersions in the vertical plane. This allows the system designer to create a sound reinforcement solution that is extremely accurate at distance, which keeps audible reflections and thus unwanted reverberation to a minimum.

All three variants are two-way active designs, each containing eight 8″ mid-range transducers and four 1.4″ exit compression drivers mounted on Outline’s unique waveguide.

The enclosures are constructed from an extraordinarily tough and waterproof elastoplastic and all three models can be freely integrated with their companion subwoofer, STSUB-215.

Outline - STADIA 28 - Stadia


The STADIA 28 is a new addition to the very successful STADIA family of loudspeaker systems, designed for the largest sports venues and arenas. STADIA 28 is designed for outdoor areas such as stadiums, theme parks, leisure facilities, tourist attractions and public spaces.

The enclosure mounts two 8″ partially horn-loaded mid-woofers and a 3″ diaphragm compression driver loaded on a waveguide with a unique proprietary design. The loudspeaker systems can be arrayed in either vertical or horizontal orientation, for example with just six cabinets providing a full 135-degree coverage in both deployments.

STADIA 28 implements the Outline V-Power concept to control the coupling between the array modules, and all the radiating surfaces of the cabinet are perfectly symmetrical.


STADIA STSUB-215 is the companion subwoofer for Stadia and Arena Series, featuring the same ‘OutSide’ weatherproofing system and extending the applicational usefulness of the Stadia/Arena Series further. The sub contains 2 bass-reflex loaded 15″ neodymium woofers and is extremely high efficiency and power handling capability.

The enclosures are constructed from birch ply finished with ‘outSIDE’, an extraordinarily tough and waterproof elastoplastic coating which interacts with the cabinet material to provide extreme levels of long-term protection.

The STSUB-215 modules are all fitted with eight (8) M10 rigging points made of corrosion-resistant anodized aluminium alloy (Ergal) allowing plenty of mounting options.

Outline - ARENA 215 CX - Stadia


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.

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.
