Building on the platform of the Blue, the Gold is a higher-powered, Alnico-magnet speaker that recreates the unmistakable sonic signature of a ʽwell played-inʼ original. Over time, the high frequencies of a Blue soften and become less chalky as the cone becomes more flexible – a much sought after characteristic that the Gold exhibits straight out of the box. Also present in the Gold sound from the outset is an added warmth and complexity in the midrange which, coupled with the classic Alnico qualities of a laid-back attack, rounded low end and brilliant belllike highs, deliver huge rhythm voicings and saturated vocal lead tones.

The Gold is a wonderfully expressive and revealing loudspeaker, affording guitarists an unprecedented degree of dynamic control. It has already become a favourite for many working players worldwide whether picking and bending with Brad Paisley, or rocking hard with Danny Spitz of Anthrax.

• 12” neodymium woofer offers 300Wrms (AES) continuous power handling and 98dB sensitivity
• 3” high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
• M-roll surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range
• Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio
• Intelligent heat management in both chassis and magnet assembly design further minimizes distortion
