The SBA-121 employs a 21-inch long-excursion driver in an optimally tuned vented enclosure. It is an ideal choice for applications requiring precise transient response and low bass extension in a compact very high output package. The SBA-121 is frequently used as a single unit, or in multiples to create cardioid bass arrays. Its compact size fits well under stages or on stage, and dimensionally matches the HLA-16 in flown arrays.
