i22SUB is a horn-loaded low frequency enclosure featuring proprietary symmetric loading (patent pending). As a horn-loaded design i22SUB is able to maintain high efficiency and extremely fast peak response with low distortion even at high sound pressure levels.

i22SUB features dual 12” neodymium magnet cone drivers. Unique enclosure design also enables the use of 15mm birch plywood still maintaining rigidity with free of unwanted vibrations. This makes the enclosure lighter than average without using fibre-class or other composite materials. The extremely slim profile (height only 400mm) enables easy installation under stage, into a roof area or virtually any acoustically preferred location.
