Surprisingly excellent!

I originally purchased this woofer as a test bench sub woofer, as its advertised frequency response was perfect for my setup. After giving the woofer a thorough break in, I was amazed at how clear this woofer played. The woofers clarity was on par with much higher end units costing 3 to 4 times as much. It performs, albeit not as loud as the hertz ML 2000.3, but much the same in regards to its articulation in a wide range of frequency playing easily as low as 32 hz to as high as 500 hz. For this reason I will be buying another and I will be using this sub in my front stage as a mid bass speaker. Great job audioControl, and as always Sonicelectronix.com is the best.
