KlipschR-100SW 10" Subwoofer, Incredibly Deep Bass and an All-digital Amplifier,14 5" x 12 5" x 16 4"

Fantastic for the price. Even if you can spend more you probably don’t need to. Sounds warm, punchy and not muddy at all. Just make sure you find the sweet spot on the volume and low-pass filter and these will hit the spot!Btw - connected this sub to my new Klipsch R-40PM bookshelf speakers and they play perfectly together! I purchased those for over 50% off during the Father’s Day sale and for under $500 you’d be hard pressed to find a better 2.1 setup!

Great sounding sub! I ordered this to replace my Klipsch sw-450 that finally kicked the bucket and couldn't be happier. Same size sub in a slightly more compact package and for a reasonable price. Nice booming bass that rattles the windows (the neighbors). Don't think you can go wrong with Klipsch.

This Klipsch unit was number 3 on my short list of subwoofer choices. It came behind the Elac Debut 2.0 Subwoofer to pair with my Elac Debut 2.0 B2.6 (Amazon 1/21) which was on ebay as a cosmetically beaten up department store floor demo which I'm sure audio-wise got about as much attention as the wall moulding. The other was the JBL Sub 550p, a $600 machine on sale at Harmon for $200. This was a sealed cabinet, 50lb monster and I really lusted for it. Unfortunately, my funds finally came through 2 days after the Elac was sold and 1 day after the JBL's sale ended. Poor me, it was the Klipsch or nuthin'. As it happened, I was able to save myself a little $$$s by going for the Amazon reduced price option where I found a warehouse damaged item. It ended up being perfect and new in every important way.So as it turned out, poor me... nuthin'! Right out of the box this machine is a solid, imposing, impressive, almost monolithic piece of furniture. Set-up is easy as my HK 3490 Receiver has an RCA Sub Out. The Elac speakers are very inefficient at 86db sensitivity, so I set the gain dial at only 9:00 o'clock. The instructions advised 12:00 be the baseline vollume for a receiver hook-up like mine, but that turned out to be incorrect. At this point my understanding of LFE vs Line Level Output is still rather vague. I had also thought that a low crossover setting of 55-60 hz would suit the Elacs, rated for a 44hz low but I was wrong. I'm finding that 90 - 100 hz will still complement the speakers while supplementing their output, adding just a bit of low-end oomph.And after a short 10 day break-in period, I'm finding I'm really liking that bit of oomph with the cello of a Beethoven string quartet or the tympanic rolls of a Bartok concerto, instruments that I can now feel in the pit of my stomach.. But when I put on Romantic Warrior of Return To Forever or Imaginary Worlds of Sammy Figueroa and crank up the 120 wpc of the HK, the Klipsch, at present settings is more than enough force to knock me down and beat me up. Ahhhh....hurt me.To conclude, after break-in the bass on this unit is clean and tight and real powerful when you need it to be. At any of the Amazon pricings it represents an excellent buy and if you're looking for a sub for a medium range audio system it definitely merits your strong consideration. I'm certainly happy enough.

This is an entry level Klipsch subwoofer nevertheless it's a Klipsch. I paired it with Klipsch Flexus CORE 100 soundbar to give me more low end. Due to space I didn't buy the core 200, and although pleased with the soy from the core 100, it needed some umph but didn't want to spend more than the soundbar cost. Looked at rockers and some other bargain brands around $100. Decided to spend a bit more and get a quality sub. Glad I did as this sub paired with the Klipsch core 100 sound awesome! Klipsch makes a quality product that won't break the bank.The knocks o would give are the adjustment knobs. There are two but the labels are impossible to read. A slight move of the knob makes a large change. Also the power toggle is poorly labeled. The switches seem cheaply made.buy guess Klipsch has to save money somewhere. Still has good sound and yes I would buy again

Bought this sub, needing only to supplement a 5.1 channel speaker set that I inherited. I bought a Sony home theatre/stereo receiver to run those but needed a powered sub. Enter this this little beast which packs serious punch. It is very responsive and produces clear bass tone across it's frequency output spectrum and has plenty of resonance and thump if positioned and tuned well to your system. The gain level adjustment is helpful and a little gain goes A LONG way with this unit. Additionally the frequency cut off dial (low-pass) is useful for blending where your bookshelf or floor speakers drop their low end. You can use to get everything sitting nice together. Great unit, highly recommend for your general purpose music or home theatre listening experience. Great price!

Pretty firkin good. I needed another sub because this house I have eats base somehow. I have an SVS $700-1000 no port sub next to my workstation and it is not putting out enough of a reference sound, because of the weird acoustics of the house. I bought this sub to fill in and it delivers in spades. I own many Klipcsh speakers. I have the reference from years ago (that sound amazing) to the Reference Premieres in the living room. This crappy $200 sub may be better than the SVS $700 sub realistically. I would recommend getting two of these than the SVS. 2x the $700 is $1400. Two of these subs are $400. The SVS really shine with the giant subs..

I have 4 subwoofers between $100-300, and this is by far the best. Not even close! No buzzing, no interference, no humming. I will mention that when I connected it to my studio speakers' Sub Out port, this sub had a constant low-frequency hum. I fixed this by disconnecting the sub from my speakers and connecting it directly to my PC with a 3.5mm stereo splitter, so the audio is sent to my speakers and sub separately. The sub doesn't sound as good since the highs and mids are not filtered out anymore, but it still sounds better than the hum I get when connected to my speakers.
