Short answer: the Definitive Technology BP-9020. It ranks #31 of 56 floorstanding speakers by sound quality at $500; the SVS Ultra Evolution Pinnacle ranks #39 and costs $4999.98, so there is not much of a tradeoff to weigh.
What the Definitive Technology BP-9020 offers: Integrated powered 8” side-firing subwoofer with a 150-watt Class D amplifier provides exceptional sub-bass extension down to an F3 of 35Hz and F10 of 29Hz without requiring a standalone subwoofer enclosure. Watch for: Significant high-frequency boost creates notable treble brightness and noticeable sibilance on vocal s-sounds.
On the SVS Ultra Evolution Pinnacle side: A large curved-baffle tower built for time alignment: a 1” dome tweeter flanked by two 5.25” midranges above two 8” mid-bass drivers, plus a matching pair of 8” drivers and dual ports on the back. Set against that: Not a fully linear speaker: a dip in the upper midrange followed closely by a peak (roughly 2-3kHz) gives vocals and other midrange content a shouty, forward quality that toe-out alone doesn’t resolve.
Buy the Definitive Technology BP-9020. It ranks higher for sound quality than the SVS Ultra Evolution Pinnacle and costs less, so there is no real case for the other one.

Definitive Technology BP-9020: $500.00 Discontinued
Pros: Integrated powered 8” side-firing subwoofer with a 150-watt Class D amplifier provides exceptional sub-bass extension down to an F3 of 35Hz and F10 of 29Hz without requiring a standalone subwoofer enclosure. Forward-Focused Bipolar Array technology (dual 3.5” front midrange drivers + 1” annealed aluminum dome tweeter, plus a 3.5” rear-firing midrange driver) creates a remarkably wide, spacious soundstage with broad room envelopment. On-axis frequency response stays smooth and relatively neutral when listened to directly aligned with the tweeter. Measured average sensitivity of 87.7dB SPL (2.83V/1m) allows comfortable drive from standard multi-channel receivers.
Cons: Significant high-frequency boost creates notable treble brightness and noticeable sibilance on vocal s-sounds. Bipolar rear driver radiation creates a diffuse soundstage that compromises razor-sharp imaging focus and pinpoint instrument placement. DSP-based internal limiter aggressively compresses output below 80Hz at higher listening levels, causing lower mid-bass and sub-bass impact to diminish as volume increases. Midrange clarity shows slight ‘cuppiness’ and upper-frequency directivity irregularities due to front/rear driver interaction. Discontinued.

SVS Ultra Evolution Pinnacle: $4,999.98 SVS
Pros: A large curved-baffle tower built for time alignment: a 1” dome tweeter flanked by two 5.25” midranges above two 8” mid-bass drivers, plus a matching pair of 8” drivers and dual ports on the back. Impulse-response testing shows a single clean arrival rather than the staggered tweeter-then-woofer arrival typical of conventional flat-baffle designs, confirming genuinely effective time alignment. Excellent build quality throughout. Very wide, consistent horizontal radiation around ±70-80° gives a large, enveloping soundstage. Capable of very high output with very low harmonic distortion - the reviewer says this measured the lowest harmonic distortion of any speaker he has tested to date, at both 86dB and 96dB output, with distortion staying under 1% down to 40Hz.
Cons: Not a fully linear speaker: a dip in the upper midrange followed closely by a peak (roughly 2-3kHz) gives vocals and other midrange content a shouty, forward quality that toe-out alone doesn’t resolve, pointing to a genuine on-axis response issue rather than just room reflections. A wide, high-Q bass bump around 70-80Hz makes the speaker sound boomy unless pulled at least 3 feet from the rear wall or tamed with EQ (a -3dB cut with a Q of 1 around 70Hz worked well in testing). Minimum impedance dips to about 2.6 ohms around 80Hz, a genuinely demanding load - the reviewer could not drive these to satisfying output with budget-oriented amplifiers and receivers, and recommends a robust stereo amp or monoblocks instead. At around 100 lbs and roughly 4 feet tall with the tweeter about 32.5” off the ground, seating position matters: straying beyond about 10° of the tweeter axis loses real detail in the upper midrange, and the crossover region shows lobing that shifts from about 10° to 50° between 2-4kHz. Multitone distortion and dynamic compression both increase in that same upper-midrange/tweeter region at higher output, consistent with the on-axis dip-then-peak character.
