      The spectral decay is amazingly good. Tight accurate bass with dynamic midrange. Used in Time Keeper monitor ,Tyler acoustis $ 2500. Bought one driver to experiment with and roll of with simple x over is smooth. Cross at 1800 to 2600 Hz no problem. For 35 bucks don't hesitate to get. Can vent to really make it throw some long wave lengths. Thanks Michael
