A unique 2 way bass system employing Tuned Dipolar Array
Technology. Includes 4x 12" Woofers (vented) and 4x 8"
woofers (sealed) in a trapezoidal enclosure.
The MQTD812 uses patented Tuned Dipolar Array (TDA)
Technology to achieve unprecedented LF directivity in the
vertical plane without enormous horns or baffles. The com-
pact, high output LF system works with MQ Series
mid/high modules to create true 3-way arrays in large for-
mat installations. A powerful tool where LF directivity is
required. Six year warranty.
