Optimal Audio Cuboid 3 FAQs
Cuboid 3 is a two-way, passive 3″ loudspeaker for wall-mounted commercial audio installations. Its compact ABS cabinet, portrait/landscape mounting system and included wall bracket make it suited to distributed background music and speech applications in a wide range of venue types — bars, restaurants, retail, hotels, offices and education. The 3.5″ LF driver and 0.5″ PEI dome HF driver LF driver delivers a maximum SPL of 98dB continuous and 104dB peak, with a 130° horizontal by 120° vertical coverage pattern for consistent dispersion. IP54 outdoor capability is available with the accessory weatherproof terminal cover.
The Cuboid range covers 3″, 5″ and 6.5″ ABS cabinet models — all sharing the same portrait/landscape mounting system and IP54 outdoor capability with the accessory terminal cover. Cuboid 3 uses a 3.5″ LF driver and 0.5″ PEI dome HF driver and delivers 98dB continuous SPL — suited to smaller spaces where discretion is the priority. Cuboid 3 (3.5″ LF, 98dB) is the most compact and discreet. Cuboid 5 (5.25″ LF, 105dB) steps up in output for larger spaces. Cuboid 6 (6.5″ LF, 108dB) is the highest-output ABS model. For larger installations requiring wooden cabinet construction and higher SPL, the Cuboid 8 through 15 range continues the series. Your installer will advise based on room size, throw distance and ambient noise level.
