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.

    I have two of these now... I had to get a second to max my receiver at 7.2. It sounds great; even on carpet it isn't muffled, and the second one, in a corner, isn't "boomy," either. They're a little quiet out of the box, but nothing a couple adjustments on my receiver couldn't fix (which you should be setting anyway).

    I’m pretty happy with my purchase. This isn’t the loudest subwoofer, but this does a pretty decent job with the low end, and makes my system sound very balanced with what I have. I wish there was a remote to turn the sub on and off. The standby mode hasn’t worked very well for me. It would turn off ok, but has a problem turning itself back on when needed.

    This subwoofer is an excellent subwoofer for the clean quality low bass frequencies it produces. When you compare the price with the competition, this Sony subwoofer wins out. It's hard to find a speaker that does this good of job for this price.

    Bought a new surround system and the old subwoofer would just hum. Tried cables, connectors and rerouting cables, still hum. Bought this one and used the same cables and no hum at all. Love the bass sound too!

    I am going to roll out some adjectives like brawny, hefty, mighty might to describe this SONY sub-woofer. It replaced another brand and it was money well spent. It provides a great distortion-free bottom to my recorded and streamed music as well as movies, television and other streamed content.

    Have this in my garage, 12’ ceilings and about 650ft2. IT sounds pretty decent although it struggles with low bass…mid bass it really shines. For $115 on Black Friday I couldn’t pass it up.

    I hooked this unit up to my system and it rocks the house. I like the fact that I can leave it plugged in and turned on it has a standby feature that shuts down the amp until it sees power to the speakers from the amp.My old Infinity sub amp blew up because it didn't have this feature.

    When this subwoofer was hooked up to the sound system, it was magical! A rich, full sound emanated throughout the room. It was not overwhelming but balanced with the existing surround sound speaker system.

    Works as advertised, Nice unit. BUT...it's heavy, however, all of them are. The controls for volume and frequency rotate too easily. It's too easy to change their settings by accident. Everything on the back should be labeled in a contrasting color like white. I have to use a flashlight to read the printing.
