12″ Tone Tubby Alnico


The Flagship Tone Tubby Alnico 12 offers an amazing range of tone, in the guitar frequency range. More overall lows, mids and highs, with NO “cone cry” or “ice pick highs”. A smooth and warm tone, with a mid-range airiness and fat, silky and thick overdrive without any harsh high end and no “farting out” like other low-wattage Alnico speakers. In a recommended open back cabinet, the mid-range airiness provides the most 3-dimensional tone, when compared to the other speakers.
