The sandstone XT550 5.25” 2-Way Outdoor In-Ground Speaker from SoundTube Entertainment is an outdoor loudspeaker solution for full-range background/foreground music and paging. The sealed, in-ground enclosure design delivers true low end response (62 Hz, - 10 dB) and optimal off axis performance. The Speaker includes theft-resistant mounting hardware and a weatherproof 5-position tap switch for 25/70.7/100V applications with 4â¿¦ voice coil direct position.
The BroadBeam dispersion technology utilizes an advanced diffuser/tweeter system to provide maximum dispersion of the higher frequencies throughout the 360° horizontal by 40° vertical coverage pattern. The enclosure is engineered for durability and performance. It incorporates ZeroReflection internal shaping to create an effective environment for sound reproduction.
The wide 360° horizontal dispersion pattern makes the XT550 Speaker suitable for use in theme parks, promenades, playgrounds, shopping malls, restaurants, resorts, gardens, and other outdoor applications. It comes with in-ground anti-theft brackets and stainless-steel square-tip screws for increased outdoor security.
