Short answer: the JBL 4305P. It ranks #40 of 119 powered bookshelf speakers by sound quality, rated 4.4/5, at $1,499.99. The Klipsch The Nines ranks #66, rated 4.2/5, at $899, $600.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the JBL 4305P does well: Powered speakers with studio accuracy plus streaming, optical and USB inputs, made for a living room or desk. Watch for: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.
The case for the Klipsch The Nines: Powered horn speakers with even mids, solid bass, HDMI ARC and a phono input, convenient for both TV and music. The tradeoff: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span.
Buy the JBL 4305P. It is rated higher for sound quality, and the $600.99 saving on the Klipsch The Nines is not enough to make up the difference.
