Klipsch 2-Pack R-100SW 10" Subwoofer, Incredibly Deep Bass and an All-Digital Amplifier,14 5" x 12 5" x 16 4"

Amazing price for a sublime sounding subwoofer! Powerful but NOT boomy. Very precise flat response from Denon receiver sub out. Timber matches well with medium Polk Audio fronts and center channel speakers.

Great sound, easy to set up, and not too intrusive in size for our living room. Works well with the Klipsch RP 600 bookshelf speakers.

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

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.

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!

Really good speaker I'm happy! the Build quality is strong and beautiful. The value for this of money is worth it! The weight doesn't bug me!

I don’t have anything to write home about… just an old Technics rack unit combined with Bose 301 Series III speakers I picked up cheap and used to replace the original tower speakers. The Bose speakers definitely fit the “No highs, no lows, must be Bose” mantra. But then, so did the old tower speakers. I just wanted to eliminate the old tower speaker footprint.In an effort to get more bass, I came to the realization I needed a subwoofer with the Bose 301’s, and any gain I had made regarding the footprint of the old tower speakers was going to likely be nullified by the addition of a sub. I decided to go with the Klipsch R-100SW sub. I didn’t have a subwoofer jack, so I replaced the existing jumpers between the “Pre Out” and “Main In” jacks with MMF “Y” connectors and ran a left and right cable to the sub. Setup was very simple.After setting the crossover (about 1/2) and the gain (only about 1/3)… I got exactly what I was looking for… more depth and warmth to the music. As an added bonus, the Bose speakers actually sound MUCH better now. For the record I’m using it with just about every style of music imaginable, and it performs well regardless of the genre.My only question is, “Why did I wait so long?” In hindsight… this was a no-brainer. I still saved on footprint because this sub has about the same footprint as ONE tower speaker… and the quality of the bass reproduction is MUCH better.
