Short answer: the Dynaudio Emit 30. It ranks #46 of 59 floorstanding speakers by sound quality; the Bose 901 Series V ranks #59.
On the Dynaudio Emit 30 side: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. The catch: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven - sometimes soft, sometimes forward - depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result.
What the Bose 901 Series V gets right: Historically distinctive direct/reflecting architecture uses eight rear-firing and one front-firing full-range drivers to create a very large, room-filling presentation. The tradeoff: 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 Dynaudio Emit 30 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 both of these and look higher up the 59 floorstanding speakers instead.

The Two Speakers In Full
Dynaudio Emit 30: $1,274.25 Amazon
Pros: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. The two woofers hand off at staggered crossover points (around 1kHz and 3.5kHz) rather than sharing one, which avoids the acoustic lobing a shared crossover point would cause between the tweeter and the lower woofer, and adds a few dB of sensitivity in the process. Genuinely deep bass for a speaker around this price - measured F3 near 44Hz and extends audibly down to about 40Hz in-room without much difficulty. Harmonic distortion measures clean and low at both 86dB and 96dB SPL/1m. Good CTA-2034 sound power and uniform directivity mean the speaker takes EQ correction well if a listener wants to dial in its one tonal weak point. Dynamic range and compression performance are strong overall, with only a minor, high-Q compression artifact tied to a cone-edge resonance that’s unlikely to be audible. Wide, consistent horizontal dispersion around ±70° with just a small ~10° narrowing between 1-3kHz, and a reasonably forgiving ±20° vertical window centered on the tweeter axis.
Cons: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven - sometimes soft, sometimes forward - depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result. A cone-edge surround resonance shows up around 1-1.3kHz in burst-decay measurements (a trait the reviewer has also seen on other Dynaudio models) and lines up with elevated multitone distortion across roughly 600Hz-1.5kHz. An enclosure resonance appears around 350Hz in the impedance curve. Placed too close to a rear wall, the dual ports make the bass noticeably boomy - pulling the speaker out is needed to keep the low end from overloading the room. Fully resolving the top-end inconsistency needs a modest EQ correction (roughly +2dB with a Q of about 1, centered 3-6kHz), so out-of-the-box tonal accuracy in that band isn’t quite class-leading despite otherwise strong measured performance.

Bose 901 Series V: Used availability Discontinued Amazon
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.
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.
