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.

    Was a replacement for a Definitive sub for home AV. Works fine, plug and play, adjustments in back. Got it on sale.

    Purchased this subwoofer because my surround sound was all hi end sound and needed some bass to get the full experience. This subwoofer did the trick gives great low end sound to balance the surround sound experience.

    Great sounding subwoofer. Have an old mid 90s Sony receiver and it hooked right up to it. Makes watching tv or listening to music much better now. Rumbles the room now making the experience much better. Great value for the price.

    Works as advertised. I have plenty of low-end in my 5.1.2 home theater setup. I actually had to back off a bit on the sub after auto calibrating with my Sony Receiver. It puts out a great bassy sound. TV and movies sound great with my complete speaker set up. Holiday price was good.

    The sound quality of this Sub is great. I am thoroughly satisfied with this product. My only real gripe with it is that the length of the power cord is maybe four feet long. Naturally I needed five feet to reach the outlet, but I made things work. Otherwise, I am definitely satisfied with it completing my steroe set-up of a Sony receiver and two bookshelf speakers.
