Soundbars have grown in popularity by a lot recently. Typical home theater soundbar systems pair a bar with a dedicated subwoofer for handling the lows. However you may not have room to house a subwoofer or maybe you simply don't prefer having one. In that case if you want some all in one package that also digs deep, the Klipsch Flexus Core 300 is a great option to pick up at the moment as the product is currently at its lowest price ever (purchase link under the specs table down below).

Like the previous Flexus Core models, the new 300 variant is again a result of a collaboration between Klipsch and Onkyo as it pairs Klipsch’s speaker-craftsmanship expertise with Onkyo’s audio electronics engineering.
At its core, the Flexus Core 300 is a 5.1.2-channel Dolby Atmos soundbar packing four front-firing drivers, side-firing speakers, up-firing Dolby Atmos drivers, a horn-loaded tweeter, and integrated dual subwoofer pairs. Klipsch says this setup delivers strong low-end performance without requiring a separate external subwoofer as it claims to go down to 43 Hz (probably at -3dB). If you want bass that's even deeper, the unit comes with a subwoofer lineout.
One of the standout features is built-in Dirac Live room correction technology. Klipsch describes the Flexus Core 300 as the first soundbar to integrate Dirac Live directly into the product, allowing the system to analyze room acoustics based on your seating position and automatically optimize sound output accordingly.
The soundbar also supports several streaming platforms including Apple AirPlay, Google Cast, Spotify Connect, TIDAL Connect, and QPlay. Through the Klipsch Connect Plus app, users can adjust EQ presets, activate Night Mode, enhance dialogue clarity, and manage additional settings.
For users looking to build a larger home theater system, the Flexus Core 300 can be expanded with optional Flexus surround speakers and additional subwoofers (like the Flexus SUB 200 12-inch or the SUB 100 10-inch variant) using Klipsch Transport technology.
