Customers are saying

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.

    Sony is the best for my music sound system. I had bought speakers from sony and it last more than 15 to 20 years and still working. I love sony and the sound quality is excellent.

    Bought this to replace 12yo Sony 5 channel system. Seems same as the older system. HOWEVER we're using 2 floor speakers, center and this sub. When 2 remaining speakers are purchased I would hope it would out perform my older system.
