The UBS 2-12-2 is the highest output low profile speaker we make. Its double 12" Neodymium woofers give it great mid-bass detail & impact. The 2" Neodymium compression driver has mid-range output that a 1" can't match. The UBS 2-12-2 is an excellent choice as a high output vocal reproducer and works well with a subwoofer for a high output full range operation. The entire UBS line was birthed and designed as a solution to the low-ceiling related problems that arise during house of worship install situations. It is popular in houses of worship and club situations with our contractor clients.
