Customers express satisfaction with the Core Series 10" 115W Active Subwoofer, particularly praising its great sound quality and powerful bass. The subwoofer's awesome price, ease of use, and small size are also appreciated. A minor concern is the cable length, with some customers wishing for a longer connection cable option.

    This unit replaced an older subwoofer. I was hesitant to purchase this but given the price and the fact it was complementing my Sony floor speaker it made the decision easier. It has very good lows and works well for both movies and music entertainment. No regrets.

    My pioneer sub died and needed to replace so i got this as a replacement. If it was lame id send it back. But im keeping it good rumble. You probably want to get feet to decouple from the floor.
