    Not bad high bass with a little low for a 10 incher. Works well in my garage with my other 7 subs.

    I have had several subs in the last few months but this is the best. Has pretty deep bass and it's not boomy. The best thing is it works good with movies and music. Let it break in for a few days and you will hear a big improvement.

    Good amount of bass to add to my Sony tower speakers at the right price. The subwoofer has separate controls in the back for gain and to adjust the bass frequency from 80hz to 125hz. Purchased it on Black Friday and it was well worth the money. Subwoofer also has a standby mode so you don’t have to shut the unit off every time you power down your system.

    Good subwoofer for the price. Only downside is the energy save mode kicks in too fast. If the movie or show has a minute or two of low action it clicks off, then clicks back on when sound kicks in. Lot of clicking! Otherwise good product

    Subwoofers deliver the low end sound, deep base that many standard speakers can’t deliver- but they are expensive and big. Sony here tries to go inexpensive and smaller but as a result the bass output isn’t the greatest. You get what you pay for in this case. It’s substantially less expensive than other subwoofers and it does deliver some base, but not Earth-shattering performance by any means. Good for small rooms or a budget-minded shopper.

    I'm so glad I was able to get this on sale since it's not something I NEED. It really does add more to movies. Sounds great I'm very happy with it. I have a Samsung that came with a sound bar and this blows that out of the water. Great job Sony!
