Klipsch Flexus Core 300 in Black — the Flagship of the Flexus Line
The Black finish of the Klipsch Flexus Core 300 sits at the top of Klipsch’s Flexus soundbar lineup, and it’s a genuinely different product from the Core 100 and Core 200 below it — not just a bigger box, but the first sound bar on the market with Dirac Live® room correction built in, plus side-firing surround drivers that the smaller Flexus bars simply don’t have.
Antonio’s Pick
“The Core 300 is the Flexus model I point people toward when they want one box to do almost everything a multi-speaker home theater does. Dirac Live actually measures your room and corrects for it, which is a real, measurable step up from a generic EQ preset — I’ve seen it clean up boomy bass in awkward rooms more effectively than most people expect from a sound bar. The honest trade-off is that it’s a bigger investment than the Core 100 or 200, so if your room is small or your budget is tight, it’s worth comparing all three side by side in the showroom before deciding you need the flagship.” — Antonio Romeo, Owner, CapitalSound.ca
13 Drivers and 285 Watts, in One Bar
The Core 300 packs 13 total drivers into its 54"-wide cabinet: four 2.25" front-firing drivers and a 0.75" horn-loaded center tweeter for the front stage, two 2.25" up-firing drivers for Dolby Atmos® height effects, two 2.25" side-firing drivers for wider surround imaging, and four 4" integrated woofers for bass — all driven by a combined 285 watts of Onkyo-engineered amplification, more than either the Core 100 or Core 200.
The World’s First Sound Bar with Dirac Live® Built In
Klipsch built the Core 300 around Dirac Live® room correction, a technology more commonly found in dedicated AV receivers. Using the included calibration microphone, Dirac Live measures both the magnitude and phase response of the bar in your actual room, then applies correction to tighten up bass response and improve overall clarity and imaging — something a fixed EQ preset can’t do, because it has no idea what your room is doing to the sound.
Wi-Fi®, Multiroom Streaming, and Smart Home Control
Unlike the Core 100 and Core 200, the Core 300 adds built-in Wi-Fi® alongside Bluetooth®, unlocking Apple AirPlay 2, Chromecast built-in, Spotify Connect, and Tidal Connect for direct streaming without pairing a phone over Bluetooth® every time. It’s also compatible with Control4 and RTI control systems for custom-install and whole-home integration, and supports both Dolby Atmos® and DTS:X decoding.
Audition the Flexus Core 300 in Our Ottawa Showroom
I’d invite you to book an appointment at our Ottawa showroom to hear Dirac Live® room correction measure and tune itself to a real room, and to compare the Core 300’s side-firing surrounds and Wi-Fi® streaming against the more affordable Core 200. Our team can also demo it paired with the Flexus Surr 200 Atmos surrounds and Sub 200 subwoofer, with delivery and installation support available Canada-wide.

Frequently Asked Questions
What actually sets the Core 300 apart from the Core 200?
The Core 300 adds built-in Dirac Live® room correction, two extra side-firing surround drivers (13 total drivers vs. 9), more total power (285W vs. 185W), a wider 54" cabinet, and built-in Wi-Fi® for AirPlay 2, Chromecast, Spotify Connect, and Tidal Connect — the Core 200 relies on Bluetooth® only.
Do I need to run Dirac Live® calibration for the soundbar to work?
No — the Core 300 sounds great out of the box. Running the guided calibration with the included microphone is optional but recommended, since it measures your specific room and can meaningfully improve bass evenness and clarity.
Is the Flexus Core 300 available in Canada?
Yes. Capital Sound is an authorized Klipsch Canada dealer and carries the Flexus Core 300 in Black, subject to available stock.
