Klipsch is new Flexus Core 300 SoundbarThe company is the first in the industry Dirac’s Live Room Correction Technology Dirac Live optimizes the sound for the room it’s in and where the listener is sitting. Dirac Live is typically only found in amplifiers and receivers that are part of more complex and expensive home theater setups.
The $999 Flexus Core 300 is “due for release this winter.” According to What is Hi-Fi? It features eight side-, front-, and upward-facing 2.25″ speakers, plus four 4″ subwoofers. Connectivity includes Wi-Fi, Bluetooth, Ethernet, 8K pass-through HDMI, HDMI eARC, USB-C, and a digital audio port. Switching inputs and adjusting settings like EQ is done through Klipsch’s Connect Plus mobile app, available for iOS and Android.
Altering sound output to fit the layout, size, and shape of a room isn’t a new feature for soundbars, but how they do it varies. Samsung’s SpaceFit Sound uses microphones on the soundbar itself to determine how sound is affected as it reverberates around the room, while LG’s AI Room Calibration uses a mobile app and your smartphone’s built-in microphone to run tests to determine what sound corrections should be applied.
Dirac Live Room Correction technology is more comprehensive, using a Windows or macOS app and a microphone connected to your laptop to measure acoustics from different points in the room the listener is sitting in. Dirac Live uses all these measurements to tune the soundbar to create a consistent, natural acoustic environment that “enhances dialogue clarity in movies and vocal purity in music.”
The Klipsch Flexus Core 300 comes with a “limited bandwidth” license for Dirac Live software, which only corrects frequencies up to 500Hz. “Full Bandwidth” License For an additional fee, soundbars offer frequency compensation across the entire range of human hearing (up to 20kHz).
