Outstanding product. Teamed up with the calibration mic and room eq wizard. So easy to use. I bought this unit to calibrate my sub and its made a huge difference improving the flatness of the in room bass response across my seating position. Very happy. Highly recommended for any home theatre enthusiast.

Extremely good value and quite solidly made.\r\nVery well thought out product that outguns traditional active crossovers and filters for a fraction of the price.\r\nSound quality is very good.
