Short answer: the SVS Ultra Evolution Pinnacle for better sound quality, the Klipsch RP-8000F II for the lower price. The SVS Ultra Evolution Pinnacle ranks #39 of 56 floorstanding speakers at $4999.98. The Klipsch RP-8000F II ranks #42 at $1800, $3199.98 cheaper.
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.
What the Klipsch RP-8000F II gets right: 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. 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.
Buy the SVS Ultra Evolution Pinnacle if sound quality matters more than the price. Buy the Klipsch RP-8000F II if the price matters more than sound quality.
If sound quality matters at all to you, skip the Klipsch RP-8000F II. It ranks near the bottom of the 56 floorstanding speakers, so look higher up the list instead.

The Two Speakers In Full
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.

Klipsch RP-8000F II: $1800 Amazon
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.
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.
