KlipschFlexus SUB 100 10" Wireless Subwoofer - Black. for Use Only Flexus Sound Bars

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 ProportionsThis 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 WizardThe 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 StealthAt 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.VerdictThe 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.

Adds a good punch svd depth to the core 200.Helps to adjust using the Klipsch app. Connected easily using the provided dongle.

Outstanding sound!

Sounds great

Really sounds very good for its size. Blends in with my organizer nicely. Very happy with this purchase as I really like Klipsch products.

I’ll start by saying I’ve owned LOTS of Klipsch gear, theyve been my go to brand for over a decade now.That being said don’t buy this system until they figure out all the nonsense.Sound isn’t that great for being such a major collab between audio giants like this product is supposed to be.Only one subwoofer can be connected wirelessly. A second one had to be wired.Less than two months in and one of them started popping and crackling to where I literally thought people were setting off fireworks in my neighborhood till I realized it was actually my subwoofer.Klipsch customer service was absolutely useless, went around in circles for weeks and weeks with my issues for this Flexus System till I finally called Amazon and argued for about an hour to get a refund from Amazon directly to buy another system (go nakamichi you won’t be disappointed)Remote stops working and the only way it works again is unplugging your bar and replugging it in, which is a pain when it’s mounted on a wall.There’s a solid delay in sound when you start videos on any platform, like a solid five seconds and then it comes on. Doesn’t matter what you do, this delay is inevitable.System looks beautiful, I’ll give it that much. Doesn’t live up to any of my expectations.

Great compliment to the Flexus Core 200 sound bar. Rounds out the sound without overpowering it.

Love the sound and ease of connectivity with the Focus 200 Soundbar.Not happy with the isolation feet. As speaker placement is on ceramic tile.Current pads are 1/8 inch rubber!!!! What is up with that.And unable to unscrew as with other Klipsch subs.Have just ordered isolation pads and hope that I can make it work.
