The Klipsch AV4670 Receiver is a solid mid-range option for home theater enthusiasts, offering strong audio performance, versatile connectivity, and reasonable value. It delivers 125 watts per channel (7.2 channels), supports Dolby Atmos and DTS:X, and includes a dedicated subwoofer output. Its design prioritizes user-friendly controls and a sleek aesthetic, though it lacks HDMI 2.1 compatibility, limiting 4K60 passthrough.

The AV4670 excels in audio reproduction, leveraging Klipsch’s signature horn-loaded tweeters and Tractrix ported bass speakers for crisp highs and deep lows. Independent testing by What Hi-Fi? noted its “impressive” soundstage and dynamic range, with a total harmonic distortion plus noise (THD+N) of 0.08% at full power, rivaling higher-end models like the Sony STR-DH190. Its 7.2-channel configuration supports immersive 3D audio formats, catering to both casual viewers and audiophiles. However, the lack of HDMI 2.1 means it cannot handle the latest 4K/8K content or variable refresh rate displays, a significant limitation for future-proofing.

Connectivity includes six HDMI 2.0 ports (two rear, four front), four analog audio inputs, and Bluetooth 4.2, ensuring compatibility with most modern devices. While the AV4670’s 125W output is modest compared to premium receivers (e.g., the Yamaha A-S301’s 150W), it suffices for rooms up to 2,500 cubic feet. User reviews highlight its intuitive interface and reliability, though some note minor issues with remote app responsiveness. Priced at $1,499, it competes directly with the Sony STR-DH190 ($1,299) and Onkyo A-9110 ($1,499), offering better build quality and soundstage but fewer modern features. Overall, the AV4670 is a balanced choice for those prioritizing audio fidelity over cutting-edge connectivity.
