The Two Speakers In Full
Klipsch The Sevens II: $1,929.00 per pair Amazon eBay
Older model: the Klipsch The Sevens (rated 3.7/5).
Pros: A 6.5-inch Cerametallic woofer and a 1-inch titanium tweeter in Klipsch’s Tractrix horn, with 200W of amplification per side. It adds far more than the original Sevens: HDMI 2.1 eARC with Dolby Atmos decoding, Wi-Fi streaming with Google Cast, AirPlay 2, Spotify, Tidal and Qobuz Connect and Roon Ready, Dirac Live room correction, a phono stage, and RCA, USB-C, optical and coaxial inputs plus Bluetooth. Klipsch rates it at 39Hz to 25kHz.
Cons: Erin’s Audio Corner has reviewed it, but the measurements the other speakers here are ranked on aren’t available yet, so it can’t be placed against them or against the original Sevens. At about $1,900 to $2,000 a pair it costs roughly twice as much as the original.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
