Short answer: the Klipsch RP-8000F II. It ranks #52 of 71 floorstanding speakers by sound quality; the Bose 901 Series V ranks #71.
What the Klipsch RP-8000F II offers: Highest sensitivity of the RP II floorstander line (~92dB measured) and the best dynamics/compression behavior of the three under load - the cleanest at high output. Dual 8-inch woofers and the highest power handling in the line. Watch for: Mid-bass sounds lean despite the dual 8-inch woofers, and bass extension disappointed for its size - expected to reach 50Hz, didn’t get there in-room. Has its own edgy upper-mid bump (2-6kHz) that’s harder to EQ out than the other two models’ issues, since it stems from the vertical horn/woofer offset rather than simple tonal balance. The most placement-critical of the three, with the narrowest horizontal (~40-50 degrees) and vertical (+5/-10 degrees) dispersion.
What the Bose 901 Series V offers: Historically distinctive direct/reflecting architecture uses eight rear-firing and one front-firing full-range drivers to create a very large, room-filling presentation. Erin measured a benign 6.2-ohm minimum impedance, so the raw electrical load is easier than many modern four-ohm speakers. The supplied active equalizer offers user-adjustable tonal balance and is integral to obtaining usable bandwidth. Watch for: Even with the required EQ, Erin measured only about 81dB sensitivity, grossly non-flat response, numerous impedance/resonance irregularities and very high distortion. Output above roughly 90-95dB at his seat became audibly poor; multitone testing reached only about 98dB before the distortion limit. The reflection-dominant radiation prevents precise imaging and makes results strongly room-dependent. It requires the proprietary equalizer and substantial amplifier power despite its benign impedance.
Buy the Klipsch RP-8000F II if sound quality matters more than the price. Buy the Bose 901 Series V if the price matters more than sound quality.
If sound quality matters at all to you, skip the Bose 901 Series V. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
