Short answer: the Polk Audio Reserve R700. It ranks #32 of 71 floorstanding speakers by sound quality; the Bose 901 Series V ranks #71.
What the Polk Audio Reserve R700 offers: Three-way design with a 1” ring radiator tweeter, 6.5” mid-range, and dual 8” mid-bass drivers in a ported, down-firing cabinet. On-axis frequency response holds within about ±2dB across most of its range, with genuinely deep bass extension (F3 40Hz) reaching into the mid-30s Hz in-room. Wide horizontal radiation of about ±70°, giving a strong, enveloping stereo width and stage-extension effect on well-recorded tracks. Good low-level dynamics - solid bass thump at quiet listening volumes without over-accentuation. Strong distortion and compression control through the bass and midrange. Real nominal impedance closer to 4 ohms than the marketed 8 ohms, so with the right amplifier it can be driven hard - a $3,000 two-channel integrated brought out significantly more life than a budget $300 unit could. Excellent value at its roughly $2,200/pair MSRP, ranking among the reviewer’s top picks under $2,500; outperforms the similarly-priced Klipsch RP-8000F II in bass extension and overall smoothness. Watch for: Compression in the high frequencies rises sharply between 96dB and 102dB output - a real limitation only at very high volumes (around 100dB at 3 meters), but a clear step down from pricier ($5,000+) towers. Horizontal directivity mismatch around 4-5kHz, where the tweeter flares wider than the midrange, can sound a bit forward - especially noticeable when toed out further into the room; sidewall absorption or curtains help tame it. Harmonic distortion crosses the reviewer’s 3% threshold around 7kHz at 96dB output, possibly contributing to that same forward quality at high volume. Narrow vertical sweet spot (about ±15° from the tweeter axis), typical of non-coaxial tower designs - more of a consideration for multi-row home theater seating than single-row listening. The ring-radiator tweeter narrows noticeably above about 7-8kHz, and toeing the speaker out more than about 20° causes the top end to fall off quickly. Needs at least 2 feet of clearance from the rear wall to avoid boomy, exaggerated bass, since it lacks the bass-shelf tuning some rivals use to allow closer wall placement. Compared to the pricier KEF R5 Meta, has narrower horizontal (and much narrower vertical) directivity, so seating flexibility is more limited.
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 Polk Audio Reserve R700 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.
