## Description

The Klipsch Reference R-121SW 12” subwoofer features a revamped 12” spun-copper thermoformed crystalline polymer woofer that is exceptionally light and provides low frequency response, minimal cone breakup, and degradation-free distortion. The front-firing subwoofer allows you to place the sub wherever you want in your space, while the all-digital amplifier delivers ample power with Klipsch signature high efficiency.

Review: 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: Great product I have four of them ✔️

## 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.
