Reference R-101SW 10” Front-Firing Subwoofer with All-new Spun-Copper 10” woofers and an All-Digital Amplifier for Premium Home Theater Sound in Black | Home theater audio with 10 inch driver, 300W peak power and active amplification

I don't have the world's best back so the light weight of this subwoofer relative to its size and performance was appealing. It has good extension and can reproduce quite low frequencies, though its EQ has a hump at about 55hz. You can EQ that out or just enjoy it, nobody is going to make you stop! Group delay is good for its size and rear-ported construction as well, better even than some vaunted performers in its on sale price range. Ample dynamic range for cinematic low frequencies and when dialed in, it has a lively and relatively quick low frequency reinforcement for music as well. I pair mine with Klipsch RP-600m (first gen, love them) and set the crossover to reinforce from about 60hz down. Its loudness has been more than enough for my space, it can overwhelm the living room it is in when movies rumble! Feel it moving that low low air into the kitchen and other rooms even. But, to be maximally fair, if you are in a very large room you might want to consider a larger diameter speaker model or perhaps a higher output unit. I've had zero complaints about it's output but it is somewhat conservative compared to the Reference Premiere subs and some competitors, and it has rock solid DSP limiting that stops it from exceeding its capabilities. In my personal use even with bass impact action films I have not met its limits!

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!

I had just returned a more premium branded sub that cost 3 times as much. This blows that out of the water! Definitely worth it. I was highly surprised. Has plenty of power and sound is deep and rumbling like thunder.

This big boy is a beast!!! Nice, clean bass that doesn't even have to be turned up high to rumble you out of your socks! This has been my favorite subwoofer ever, AND it looks nice! It gets 5 stars with ease!

Incredible value and preform incredible.

This is very boomy, but I like the ability to turn it up and down separately from the receiver. This is my first powered sub, so keep that in mind. I've only used passive subs before this. The auto-on setting is a bit laggy, but the sub works well once it turns on. It is especially slow to turn on at lower volumes. I can live with it for the sound quality. If you put it somewhere you can easily access the back, it can be turned on manually to speed up the process. Also, the volume and crossover knobs are in the same area, so easy access might be important. If it didn't take so long to get a signal strong enough and long enough to turn it on automatically, I'd give this 5 stars. Don't forget to buy a cable to connect it to your receiver.

Amazing - Did not realize how poorly my other Onkyo sub was responding, especially to deep bass when watching an action movie. It used to rattle and pop during those scenes - this Klipsch handles it like a champ. So much clearer and forceful. It also sounds great with music - although most of what I listen to doesn't have a deep, driving bass. Would definitely buy it again should the need arise.

Absolutely solid subwoofer for the price. Couldn't be happier with the performance

Thank you Klipsch, very very powerful sub best I ever had. Budgeting for a second one

Great product I have four of them ✔️

Estou usando esse subwoofer em uma sala de 40m2. Ele tem a presença do subgrave muito nítida e forte. Mesmo em volumes baixos. Toca muito bem, subwoofer de impacto, muito top mesmo.

故障してたので、返品した。

Linda caixa, com potência e clareza excelentes. Preencheu o som da sala perfeitamente. Vale a compra!
