    1. Good subwoofer and works wonders when used for Movies or videos but with music you have to find a certain level but even then it still lacks from what’s expected. 2. The subwoofer isn’t too heavy so it can be easily moved around and placed. 3. It tends to run very hot depending on what it’s being used for. 4. Would i recommend it…Yes but only to the right audience. 5 (Extra items inside) The wires are about medium i would say around 4 Ft for the Subwoofer cord and around 3 for the power cord.

      Hi KobeB,

      Thank you for sharing your honest review. We're happy to hear this subwoofer is a great addition to your home theater setup and it immerses you even further into movies. Your feedback is greatly appreciated. Make sure that the ventilation holes are not blocked. If the ventilation holes on the back of the unit are blocked, the interior of the subwoofer may heat up. You may also disconnect the AC power cord and cool down the subwoofer. For more details on how to make sure heat is radiated efficiently, please visit the link below.

    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.

    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.

    Alex was fantastic. I came into the Best Buy store in spring hill, FL and the staff was very helpful in helping me find exactly what i needed. Not only did they help me get a better deal qith my premium plus membership but that saved me even more money than i expected. Very happy and very satisfied with everything best buy has to offer. Theyve helped with my smart phones, stereo systems and much more.

    I initially purchased one subwoofer but loved the sound that I purchased another one a week later. Both are in my media room and the kids are going crazy over the sound. It gives you the theatre effect and the rooms feel like it vibrating with the base. Highly recommend!

    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

    I have this unit behind my couch in a dual sub woofer setup. I didn't believe it would add much to my movie experience being under $200. However I was proven wrong. On a very low setting this unit vibrates my chest and couch. Perfect for Action movies.

    Great subwoofer for the price, wouldn’t get it if was anticipating it could bring the boom to a large area, but for smaller areas, it does have tight and smooth bass, not overkill and sounds wonderful at moderate to moderate/high volumes.
