The new Titan 12Z may appear cosmetically to be the same as our Titan X12 - but, it is what is inside that matters. Titan 12Z features extreme power handling transducers with high electrical sensitivity. This results in unimaginable power handling specifications and remarkable SPL. Custom built Wharfedale Pro drivers are what makes this possible. The Titan 12Z features a category leading 3" LF voice coil and our acclaimed IRIS X compression driver with its 1.75" voice coil.
