The G10 Gold is the ultimate 10" speaker, blending unmistakable Alnico class with a rich low-end, creamy midrange and vintage chiming top-end. Springy, warm, revealing and highly expressive, it can be used singly or in pairs to add a classy sheen to any amp, or in a 4x10 configuration for higher volume depth, warmth and shimmer, with less of the boom associated with 4x12 cabinets.
