Short answer: the KEF LS50 Wireless II. It ranks #19 of 108 powered bookshelf speakers by sound quality, rated 4.3/5, at $2,199.99. The Klipsch The Sevens II ranks #101, rated 3.8/5, at $1,899.99, $300 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Klipsch The Sevens II does well: A large powered pair with 6.5 inch woofers and 200W per side, plus HDMI eARC, Wi-Fi streaming, Dirac Live and a phono stage. Watch for: 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.
What the KEF LS50 Wireless II does well: An all in one wireless stereo system with accurate, consistent sound, HDMI eARC and built in streaming. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the KEF LS50 Wireless II. It is rated higher for sound quality, and the $300 you would save on the Klipsch The Sevens II does not close the gap.
About the ratings: the Klipsch The Sevens II’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.6 to 4.0, so this verdict could change once it is measured.
