Two 15" Celestion Truvox drivers - one direct radiating, the other mounted inside the ported, birch-ply cabinet at 90 degrees - form a modified band pass system. This ingenious driver loading arrangement results in pure, natural sounding audio with a solid, tight bottom end.
This full-range, quasi 3-way, sound reinforcement system also incorporates a 75W Celestion CDX1-1745 ceramic compression driver, delivering the optimum balance between performance, efficiency, weight and cost. Not only does the QXi215 easily out-perform other 2 x 15" cabinets at this price point, this forward-thinking design means the cabinet is far more compact, making handling much easier - a real benefit for mobile applications. What's more, the reduction in panel size provides greater resistance to the driver-induced vibration, which can occur in larger, less well-constructed cabinets, say Celestion.
