Elemental force with sensitivity<\/p>\n
At the very first glance, it appears what the new Q subwoofers are designed for. The solid aluminum diecast baskets with diamond cut as well as the massive triple ferrite magnet systems clearly signalize that these subwoofers really mean it. The extremely stiff, hand-scooped cones and oversized voice coils with enormous winding height are literally predestinated to turn incredible volumes of air into deep bass sounds.<\/p>\n
Yet sheer power alone is not sufficient \u2013 numerous sophisticated technical details together with a smart mix of materials assure highest precision and detailed bass reproduction which will satisfy even most demanding music enthusiasts.<\/p>\n
These subwoofers form a perfect symbiosis of maximum sound pressure and state-of-the-art sound quality in a new dimension.<\/p>\n
