    My old Sony sub died so this is a replacement and I love that it was plug and play with my Sony receiver. It’s loud and rumbles the room just like I want.

    This subwoofer is the best purchase I’ve made after since buying my MacBook. The base is very deep and you can feel it if you have the right system. Just make sure that you put it in a corner where it’s closer to the outside wall of the house because it will reverberate through the walls

    I purchased this to compliment the built in speakers in the Sony A1E OLED TV. You connect it to the analog out and select subwoofer. Then use the Low Pass Filter control to select the amount of low end to come through the subwoofer and the gain to adjust the volume. You can mostly do this by ear, play with the controls a little and see what sounds right to you.

    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.

    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.
