Titan 12D models are bi-amplified, Class D technology is now used for the LF and HF, creating a more efficient and powerful system that is now even lighter than the previous generation. With the Titan 12D Wharfedale Pro introduce Qubit™, our new powerful and precise 24-bit 192kHz DSP processing. With advanced adaptive multi-band dynamic processing and filtering Qubit helps fine tune your system to sound natural and open. Qubit processing optimises the loudspeaker to provide smooth digital crossover points that are perfectly aligned in terms of phase response and time-domain. Protection is offered in the form of true independent adaptive LF and HF signal limiting that helps protect against thermal damage and driver over excursion. Qubit has an extended frequency response that goes way beyond the capabilities of our hearing, providing an extended phase response that remains linear throughout our natural hearing range. This enables Titan D to reproduce exceptionally natural transients and exhibit perfectly aligned time-domain characteristics.
