Review: Pleasently Surprising Oomph - Great sub! Connected this baby to my other Klipsch speakers via the sub out port and it worked instantly. (I did have to buy a separate insulated sub wire as this product does not come with one) I was able to get this on sale for 50% off and for that price it's amazing! The subwoofer is larger than expected, but I'm considering that a good thing in the end. (No need to upgrade in the future for me) The adjustable sound allows for subtle bass or wall shaking bass. All and all, this was more than I could have expected for the price!
Review: Where has this subwooofer been all my life?! - This big boy is a beast!!! Nice, clean bass that doesn't even have to be turned up high to rumble you out of your socks! This has been my favorite subwoofer ever, AND it looks nice! It gets 5 stars with ease!

## Questions & Answers

**Q: What are the differences between this and the 120sw?**
A: The R-121SW  has an updated woofer driver and a larger batter braced cabinet. It is able to produce a bit more bass and sound tighter.

**Q: When in auto position the led green light remains on even when the amp is off. is this normal?**
A: The subwoofer should shut off after about 15 minutes of no signal from the amp so it will not happen right as you shut the amp off. If the sub is still not going on standby, there may be some noise coming from the amp or wiring between the amp and subwoofer that is keeping the sub from going to sleep. Reach out to our support team through our website if you need further support.

**Q: Can you use a wireless kit with this sub**
A: You can use a 3rd party wireless kit that will connect using rca connections on the back of the sub. We do not make a wireless kit that will work with this subwoofer here. Thank you.

**Q: The product description and information say that this sub is wireless. How does it receive the signal from the receiver? Is there a transmitter, also?**
A: This subwoofer has no wireless function, looks like this is just a error in the listing description. This sub only has RCA wired inputs.

### ⭐⭐⭐⭐⭐ Very happy with it
*by A***L on December 31, 2025*

Massive upgrade from my previous 12” powered sub. Looks great and feels very solidly built. The sound is great. For the price I could not ask for more. Has far more than enough power for demanding movie soundtracks and music. Might buy a second one to use one on each side as speaker stands for my floor speakers.
