Bose flagship 901 series six in honey walnut with active eq. These speakers jam!!! sparkling highs , thunderous lows . they simply have to be heard to be believed. Do these speakers punch way above their weight class. I demonstrated a last week how these speakers hit lo frequencies is well is some 15 inch?Three way speakers. Yeah, absolutely outperform my ser in Vega.E 712 speakers . It's hard to believe all those tiny little cones pack such a wallop, but boy , they do.
