    After using a Sony 8" SA WM250 100W subwoofer for many years, this unit is a disappointment. It can barely be heard after turning the unit's volume way up and adding 5 decibels to the signal from my Yamaha receiver. It does have a deep clear sound when you can hear it, but there will be no "wall rattling" like from my previous Sony sub. What happened Sony?

    No regrets! Definitely glad I made this purchase. Love the adjustable volume which comes in handy for providing deeper bass when needed. The auto cutoff function is a plus ensuring I'm not wasting electricity when not in use. I've seen reviews that knock it's power, but the proper source and receiver adjustments it's more than enough.

    This thing has the potential to scare your neighbors that there’s a bomb going off in your house. If this isn’t enough of an endorsement, I don’t know what it. It’s what every sun should be.

    It is a great subwoofer for the money. It does need external power by plugged in wall outlet. I bought two so that I have a more realistic sound effects.
