Klipsch Flexus SUB 100 10" Bluetooth Subwoofer - Black Connect Plus App Access

Purchased after the sound bar. Great addition and worth as thye sound greatly improved. Very east connection.

Alright, buckle up for a bass-tastic ride with the Klipsch Flexus SUB 100 10” Wireless Subwoofer, the low-end lovechild of Klipsch and Onkyo that’s so thumpy it could wake a coma patient. This box of boom is built solely for Klipsch Flexus Core 100 or 200 soundbars, and it’s here to rattle your ribcage and your neighbor’s nerves with glorious, gut-punching lows. Picture a subwoofer that’s less “furniture” and more “earthquake simulator” for your living room. Sound: A Bass-Splosion of Epic Proportions This 10-inch paper cone beast, fueled by an 80W RMS (160W peak) Class D amp, doesn’t just play bass—it assaults you with it. I fired up Jurassic Park, and when that T-Rex roared, the Flexus SUB 100 made my couch shimmy like it was auditioning for a twerk team. The range delivers tight, precise lows that don’t blur into a muddy mess, unlike my uncle’s old sub that sounded like a washing machine full of bricks. From Dune’s sandworm rumbles to Metallica’s basslines, it’s crisp, punchy, and never farts out distortion. One X user raved it “shakes the room without waking the kids,” but let’s be real—crank it up, and your goldfish might start breakdancing. Klipsch Connect Plus App: Your Bass Wizard The Klipsch Connect Plus app is like having a wizard for your woof. Plug in the USB dongle, and this sub pairs faster than my mom swiping on Tinder. Adjust volume, crossover, phase, or slap on presets like Night Mode (for when your spouse threatens divorce over vibrations) or Bass Mode (for when you want to be the noise complaint). I tweaked the EQ to tame corner placement boom, and voila—no more windows rattling like a poltergeist’s tantrum. The app’s so easy, even my tech-phobic dad could make this sub sing. Design: Sneaky Sub Stealth At 13.38” x 13.19” x 13.75” and 20.7 lbs, this ebony-vinyl cube is sleeker than my attempts to slide into DMs. Its wireless 2.4GHz connection means no cable spaghetti, letting you hide it anywhere it’ll still annoy your HOA. Verdict The Klipsch Flexus SUB 100 is a bass-dropping, room-rocking riot that turns your soundbar into a sonic superhero. With app-controlled wizardry and lows tighter than my skinny jeans, it’s the funniest way to make your neighbors hate you.

I got the Flexus 200 sound bar, and added this subwoofer to add some depth to the overall sound signature. I like it so much that I am going to purchase a second unit so I can rattle the windows lol. Also, get the surround speakers; you won't regret it.

Deep bass!! This Sub is not supposed to achieve sub 30Hz. However, I've played test clips from YouTube and I can hear and feel frequencies below 30Hz. The only issue I've found (if any) is that it can't be located near my router because it emits a weird clicking noise. This can be solved by connecting the Sub using a coax cable or relocating the sub farther away from the router.

Awesome addition to my Flexus 200 soundbar! Hitting those low frequencies at lower volumes is great for apartment dwellers like me. Don't have to blast it to get bass and music/movies just sound better.
