Klipsch Flexus Core 300 Soundbar Q&A:

Does Dirac Live require extra hardware?: No - Klipsch includes the Dirac license and a calibrated microphone in the box, so you can run the calibration from the free Klipsch Connect Plus app.
Can I add a separate subwoofer later?: Yes, the Core 300 has an RCA sub-out that automatically engages low-pass filtering when you connect an external powered sub.
Will the sound bar pass 4K 120 Hz or 8K 60 Hz signals from my PS5/Series X?: Absolutely - its HDMI 2.1 passthrough supports up to 8K 60 Hz, 4K 120 Hz for lag-free next-gen gaming.
Is wall mounting difficult?: The bar has a ¼″-20 threaded insert and Klipsch offers an optional slim-depth bracket; all you need is a level and two screws.
Does it work with voice assistants?: Because it supports AirPlay 2 and Chromecast, you can initiate playback via Siri, Google Assistant or any Cast-enabled app.
How loud can it get without distortion?: The Core 300 delivers up to 106 dB SPL - roughly the volume of a live rock concert - while maintaining Klipsch’s low-distortion signature.
What streaming services are natively supported?: You can cast from Spotify, TIDAL, QPlay, Apple Music (via AirPlay 2) and any Chromecast-enabled apps over Wi-Fi.
Does Night Mode really help late-night viewing?: Yes - Night Mode compresses dynamic peaks and boosts dialog so you can hear whispers without waking the household.
