1. Small Vented Box
This enclosure is as small as many 15” cabinets but has better bass performance and handles tons
of power. This design is an excellent choice for large touring systems because it can handle a large
number of enclosures at the same load-out volume.
2. Medium Vented Box
This enclosure offers an exceptional combination of deep bass extension, high power handling and
reasonable size. It is capable of extremely high output (below 35Hz) for excellent performance
3. Large Vented Box
The large vented box produces skull crushing levels of extremely deep bass and is usable to 24Hz
(-10 dB limit) at sound reinforcement SPL levels. As is typical with large vented enclosures, power
handling is reduced about 20%.

compact size. Remarkable bass extension and power handling.
