The new Wharfedale Pro Titan™ Sub-A12, a powerful active subwoofer system designed to produce high quality audio in any performance application. The Titan™ Sub-A12 combines the newest technologies, materials and design topology to ensure absolute accuracy and high output. The TITAN™ Sub-A12 is powerful 12 inch active subwoofer. A built-in 250 watt (continuous) 500 watt (peak) amplifier conveniently accepts stereo or mono line level inputs via dual, balanced, XLR-¼" "combo" connectors. A custom designed, pressed frame 12" woofer, with a 2.5" voice coil, is utilized as the heart of the Titan™ Sub-A12's complementary low frequency enhancement system. Integral signal processing includes a dynamic AGC (Automatic Gain Control) circuit, a stereo crossover and signal limiting for the prevention of a distorted signal to the internal amplifier. A convenient and an essential PHASE switch is included to allow for proper subwoofer signal polarity to be selected. A pair of balanced XLR male output connections may be used to to send a high-pass, line-level stereo signal to a pair of powered, full-range speakers such as the popular Wharfedale Pro Titan™ ACTIVE models.
