Seventy 80
One of our best sellers, this 12 inch guitar speaker meets the expanded
frequency range often requested by the new generation of amp
manufacturers.The Seventy 80 is detailed and crisply defined, with a
tightly controlled low-end and punchy, aggressive upper mid-range. The
top-end response is also subtly increased. Used singly, in pairs or
quartets – it is capable of reproducing a wide range of sounds and styles
whilst adding the undeniable Celestion character to any amp.
