Short answer: the JBL HDI-3800 for better sound quality, the Klipsch RP-6000F II for the lower price. The JBL HDI-3800 ranks #7 of 71 floorstanding speakers at $5000. The Klipsch RP-6000F II ranks #54 at $1500, $3500 cheaper.
What the JBL HDI-3800 offers: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Watch for: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate.
What the Klipsch RP-6000F II offers: Highest power handling and clean, well-behaved compression at typical volumes. Precise imaging from the controlled horn directivity. Watch for: Worse baffle-step coloration than the smaller RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have - a real regression in tonal balance despite the higher price. Bass extension is mixed - less deep at -3dB (67Hz) than the 5000F - and needs a subwoofer regardless. Narrow horizontal dispersion (~50-60 degrees).
Buy the JBL HDI-3800 if sound quality matters more than the price. Buy the Klipsch RP-6000F II if the price matters more than sound quality.
If sound quality matters at all to you, skip the Klipsch RP-6000F II. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
