The new Tony Iommi signature 4x 12 cabinet - the TI412S, was designed to complement the tonal characteristics of the TI100.
Tony was keen to make sure that the drivers in the TS412S delivered the tone that he heard in his head and that his new signature amplifier is capable of producing. So after exhaustive testing the conclusion was reached that Celestion G12H (75) proved to be the ideal driver to partner the new TI100. The G12H 75Hz has its low end raised a little in frequency giving punchier lows and a more forward midrange. Which makes it more suited to heavy overdriven sounds in on stage environment.
