Review on EMINENCE PXB500 Pass Board Crossover by Adam Gardner

This is AMAZING. I was trying to get decent sound from a digital amp with a subwoofer channel. It had an "adjustable crossover" for the subwoofer output, but no matter how low I turned it, the subwoofer sounded like crap. It let through frequencies that were too high, and none of my subwoofers could handle it. I added this to the system and it was like night and day. I used it with a 4 ohm subwoofer, the manufacturer's site says it works down to about 250Hz. 250 Hertz. This is the maximum frequency my subwoofers are rated for. It was perfect!
