Klipsch R-12SW 12" 400W Powered Subwoofer (Open Box)

In September 2020, I started looking at subwoofers again because I was planning on upgrading some sound in another room of my home. Since Klipsch was known for having good sound at a reasonable price, I decided to purchase the R-12SW. After getting it, I tried it out and it really does have some room shaking base. That being said, I listen to all kinds of music, or should I say, all kinds of music shows up in what I listen to, and what I noticed, depending on the songs, was that some of the bass frequencies would get lost. For instance, if a lower frequency bass note was played and right behind it a bass frequency slightly higher, then that second bass frequency would not necessarily be heard. You would still get that thump, but not necessarily in the frequency you're supposed to hear it in. When I first noticed that some of the bass frequencies were being, for lack of a better term, drowned out, I thought it may have been do to how my equalizer and tone settings were adjusted. After checking and making some adjustments, I found I was still having some of the same issues, which made me feel like I was not getting the full listener experience with some of the music I listen to. When making the adjustments didn't work, I attached one of my previously purchased Acoustech (Feb 2019) subs to the system I was upgrading and found that I was not experiencing the same issue. In fact, I actually heard some lower frequencies than with the Klipsch, which disappointed me a little. All this is not to say that there is anything wrong with the Klipsch because it sounds good, but for the money, I got better sound and response to frequency change out of my Acoustech and if I had known then what I know now, I would have stuck with the Acoustech. I hope this is helpful to anyone considering purchasing the Klipsch.
