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.

| The B&C 12NW100 speaker is designed to produce bass, it is typically a 12 inch usable as a bass power speaker in a subwoofer for a compact system often transported. The 12NW100 will delight you with bass-reflex or band-pass load, its significant admissible electrical power makes it a real machine for producing bass, however, special care must be taken with the amplification dedicated to it.
