Short answer: the Klipsch RP-8000F II. It ranks #113 of 188 floorstanding speakers by sound quality (rated 3.9/5) at $1,159.98 and is still sold new; the Bose 901 Series V ranks #187 (rated 1.9/5) and is discontinued, so it is only an option used.
The Klipsch RP-8000F II is the more accurate option. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.39 against 0.43 for the Bose 901 Series V. The catch: 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.
The Bose 901 Series V is the deeper-bass pick. Historically distinctive direct/reflecting architecture uses eight rear-firing and one front-firing full-range drivers to create a very large, room-filling presentation. Its bass reaches about 55.8Hz before falling 3dB, against 67Hz for the Klipsch RP-8000F II. The catch: Even with the required EQ, Erin measured only about 81dB sensitivity, grossly non-flat response, numerous impedance/resonance irregularities and very high distortion.
Buy the Klipsch RP-8000F II. It is rated higher for sound quality and still sold new, while the Bose 901 Series V is discontinued.

Klipsch RP-8000F II: $1,159.98 per pair Amazon eBay
Same family: the Klipsch RP-500M II (smaller bookshelf, rated 4/5), the Klipsch RP-600M II (larger bookshelf, rated 3.7/5), the Klipsch RP-5000F II (smaller floorstanding, ranked higher, rated 4/5), the Klipsch RP-6000F II (smaller floorstanding, ranked lower, rated 3.9/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5) and the Klipsch RP-504C II (largest center, rated 3.8/5).
Pros: 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. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 92dB.
Cons: 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.

Bose 901 Series V Discontinued eBay
Pros: 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. Measured bass extension of 55.8Hz (-3dB), with a measured sensitivity of 81dB.
Cons: 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. Discontinued.
