Liverpool 1275 - 12" Guitar Speaker, 75 Watt, 16 Ohm

Liverpool 1275 - 12" Guitar Speaker, 75 Watt, 16 Ohm

A speaker truly worthy of The Crown!

The Liverpool 1275 is the classic British rock tone, inspired by tones from the 80’s.  A complex, thick and vocal midrange cuts through the upper-register, while nice, full, lower-mid grunt completes the warm, gutsy, tight lows.  The highs, while clear, open and articulate remain warm and ear pleasing.
