When it comes to upgrading your TV's sound in 2024, soundbars present a range of options from straightforward to sophisticated. Today we're comparing the compact Klipsch Flexus Core 100 ($349.99) with the full-featured LG S90TR ($799.99) to help you make the right choice for your setup.
Soundbars have evolved significantly over the past few years. What started as simple stereo upgrades now ranges from compact single-unit solutions to complex home theater replacements. The key development has been the integration of technologies like Dolby Atmos, which creates three-dimensional sound by bouncing audio off your ceiling and walls.
When choosing a soundbar, four factors typically determine satisfaction:
Let's explore how our two contenders address these factors.
The Klipsch Flexus Core 100, released in late 2023, takes an innovative approach with built-in subwoofers. Instead of a separate bass unit, Klipsch integrated two 4-inch woofers into the main bar. This design choice means less clutter and simpler setup, but it does limit maximum bass impact compared to dedicated subwoofers.
In contrast, the LG S90TR embraces a traditional home theater approach with separate components. Its 7.1.3 configuration means:
Having tested both approaches, I've found the single-unit Klipsch works surprisingly well in apartments and smaller rooms. However, for dedicated home theater spaces, the LG's separate components create a more immersive experience that's hard to match.
The Klipsch delivers impressive stereo performance from its compact form. Its horn-loaded tweeters (a signature Klipsch technology that helps direct sound more efficiently) provide clear, detailed highs. The built-in subwoofers generate respectable bass, though they can't match the depth of the LG's separate subwoofer.
The LG S90TR shines in movie playback. Its dedicated center channel makes dialogue clearer, while the rear speakers create true surround effects. The height channels add an extra dimension, making rain sound like it's falling from above or helicopters feel like they're flying overhead.
Both bars support HDMI eARC (Enhanced Audio Return Channel), which allows high-quality audio transmission from your TV through a single cable. However, the LG adds:
The Klipsch focuses on core functions with Bluetooth and HDMI, keeping things simple but potentially limiting future expansion.
The Klipsch Flexus Core 100 excels here. Its single-unit design means:
The LG S90TR dominates this scenario with:
For gaming, the LG's surround sound provides a competitive advantage by precisely locating sound sources. However, the Klipsch's lower latency might appeal to competitive gamers who prioritize instant audio feedback.
The price difference ($450) between these systems is significant. The Klipsch delivers exceptional value for stereo content, while the LG justifies its premium with additional features and superior surround performance.
Consider these factors when evaluating value:
Both systems represent current technology, with the LG offering more future-proofing through its expanded connectivity options and firmware update capability. The Klipsch's simpler approach means fewer potential compatibility issues but also fewer opportunities for feature expansion.
Choose the Klipsch Flexus Core 100 if:
Choose the LG S90TR if:
Both systems represent different approaches to better TV audio, each excelling in their intended use cases. The Klipsch offers impressive performance in a simple package, while the LG delivers a more complete home theater experience at a premium price point.
Remember that room acoustics play a crucial role in any audio system's performance. Even the more expensive LG won't perform optimally in a room with poor acoustics, while the simpler Klipsch might surprise you in a well-treated space.
Consider your long-term plans as well. If you might want to expand your system later, the LG's additional features and connectivity options provide more flexibility for future upgrades.
