    I want to make it clear that I been wanting a Klipsch sub for a long time. I resisted buying a cheaper lesser brand for months. My expectations were prepared to be disappointed as everything in 2020 has been. And for 1 day I was over the moon happy with this product. It was the very next morning that I could hear a low hum from the sub. At first I thought I forgot to put in Auto power on mode. It was in auto. I moved the switch to On, no change same hum. Off position no hum. So I ordered a major over kill of a RCA cable thinking I may have damaged the old one during the install somehow. I removed the old rca from the sub and the hum stopped. I removed the other end from my receiver thinking it may be loopback ground issue between the 2 devices. I then plugged in the sub side back in. The hum was instant and even louder. From what I am seeing on Klipsch’s forum and many others is the same issue. It’s not a defect it’s working exactly as intended! What the actual F*#@!!!!

    This sub’s Amp design is garbage.
    The problem is the subs 2 (3rd is ground) prong power cord which means the Amps power section is using a floating ground. When you connect your RCA cable the sub will make a low 60ish hz Hum. This is even before its even connected to your receiver (so not a loopback ground issue with anything but itself). Took a lot of forum hunting to understand the issue. No magic RCA cable is going to fix this. I have tried several high end cables and they made zero difference. Odds are like me you will not notice right away. As you will be busy making it hum on purpose playing movies and music. It’s later when it should be in sleep mode you will hear the hum. Same cables different amp with 3 prong power cable no hum. If you don’t mind the constant hum the sub will do its job and make loads of bass. Above 80hz the enclosure will resonate a bit, but from a few feet away it’s not that noticeable.

    I’m not just an audiophile, I record and produce music as well. I have a fairly well-equipped home studio, which includes a professional reference-level monitor system, with a very high quality (and high price-point) sub. I never thought I would hear a consumer-level sub for a home stereo system that sounds as good as my studio-grade sub. But, I was wrong. This Klipsch 12 inch sub is very impressive. Great tone, and captures not just the sound, but the feel of the lowest lows in your music and movies. Several previous reviews describe this sub as musical. I would agree, but it goes farther than that. It’s hard to find a sub that produces both a “tight” bass sound, while also being “smooth.” My prior home stereo sub produced a “tight” bass sound but was harsh a times and because of the smaller speaker size, would occasionally sound distorted when trying to produce the very low frequencies at nominal volume. No distortion with this sub. If you are wondering whether a 12 inch woofer it too big, it’s not. The size of the speaker helps it to easily reproduce very low frequencies without distortion, and without having to crank the volume to get the effect you want.

    Wow does this thing thump!! It will shake things on the other side of the house and is crystal clear.

    One piece of advise. Get a good sub cable. The cheap one I had cause humming when the receiver was off.

    I live on the fourth floor of my university accommodation. You can feel the main door shake all the way on the first floor. The only downside to this product is that I keep getting emailed noise complaints… whoops.

    junge junge was soll ich sagen…. die Erdbebenmaschine ist jetzt seit einer Woche in Betrieb und ich bin mehr als zufrieden. Hatte vorher das Teufel Concept C aber das ist eine ganz andere Liga hier. Ich muss nur noch eine Lösung für die vibrierenden Türklinken finden. Mein Wohnzimmer misst ca. 20qm – wie es bei größeren Räumen aussieht kann ich nicht beurteilen, habe den Subwoofer aber auch gerade mal 1/3 aufgedreht.

    This thing is awesome. I made a big mistake when I traded away my old Boston Acoustics XB6 subwoofer a few years ago. I purchased an Onkyo 7.1 speaker set and was using just the sub that came with it… it did okay, but bottomed out very easily. I finally decided it needed to be replaced, so I went with this Klipsch based on reviews I read here. It arrived well within the stated delivery window, and was up and running in less than 5 minutes. Let me tell you, this thing goes loud and deep. It shakes the walls! You know that scene in Game of Thrones where they blow up all of the ships? I thought it was going to wake the neighborhood! There’s virtually no break-in period. It sounded great from the first minute. It’s aesthetically pleasing, too. The veneer almost looks like black brushed aluminum, and the golden cone is nice to look at. And the cost is less than my old Boston that I had missed so much. Worth the buy! Go for it!

    Update 9/24/16: Well, after three months of normal use, the driver developed a rattle. It sounded like wires slapping the inside of the box,so I took the driver out, taped down any loose wires I saw, and plugged it back in. Still rattled. It was the driver itself. It still put out plenty of bass, but that rattle was annoying. I contacted the seller, and they basically said, sorry. Can’t help. Window is closed. Contact the manufacturer.
    I asked if they were an authorized Klipsch dealer (because Klipsch’s website says they only warranty items bought from authorized dealers) and got no answer. So I contacted Klipsch. They said nope, we won’t honor the warranty because Bubba Goo Goods is not an authorized Klipsch dealer, and we can’t vouch for them or their equipment. But, they did sell me a replacement woofer for $84. Three business days later, it arrived and I installed it. Rattle is fixed. Just wanted people to be warned. Amazon pricing is great, and we take advantage of the deals, but buyer beware. Amazon can be like the TJ Maxx of the internet. The prices are lower for a reason.

    Update 5/2/18: The replacement driver I purchased directly from Klipsch is still going strong. I haven’t had another issue with the sub or any of its components since the rattle incident. I am still very pleased with this sub.

    …Weil der Packetmann Schweißperlen auf der Stirn hatte….(ist doch recht groß das Ding, sammt Karton 😂), das Frauchen die Hände übern Kopf zusammenschlägt und die Augen verdreht, und der Untermieter (zum Glück die eigene Mutti) beim probehören auf einmal in der Tür steht und mir gefühlte fünf Minuten lang nen Vogel zeigt…🤷‍♂️, das ich mit fug und recht behaupten kann….Ja…. Alles richtig gemacht.

    Das Teil ist der Hammer. Verarbeitung, Preis und der abrundtiefe Bass.
    Und natürlich der super schnelle Versand.

    This is not Klipsch’s newest 12″ sub. It was first listed in 2014. It has been replaced by the Klipsch R120 SW 12″ 400W Powered Subwoofer (July 15 2018 — I also have one of these in my living room system), but it sells at twice the current listed price for the R12SW. If you can get this at half the price of the newer model, as I did, it is the buy of the year in subwoofers! I had planned to buy the older 10″ model, but for $100 more, the 12″ is a steal. I now have two of these at home (one upstairs and one in the basement), and for my needs in those sound systems, it totally outperforms. For anyone who is alert to Klipsch quality, this is almost a “have to buy” item. 5 stars.

    Subwoofer zu bewerten ist immer sehr schwierig. Persönlicher Geschmack, Raumsituation, Raummoden, vorhandene Lautsprecher, …. Klanglich fand ich den Canton AS 85.3 SC jedoch besser – meine subjektive Meinung. Ich denke, das der Subwoofer grundsätzlich gut ist – für mich hats klanglich jedoch nicht gepasst.
