Short answer: the SVS Ultra Evolution Pinnacle for better sound quality, the Sony SS-CS3 for the lower price. The SVS Ultra Evolution Pinnacle ranks #39 of 56 floorstanding speakers at $4999.98. The Sony SS-CS3 ranks #47 at $450, $4549.98 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 Sony SS-CS3 gets right: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. The catch: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments.
Buy the SVS Ultra Evolution Pinnacle if sound quality matters more than the price. Buy the Sony SS-CS3 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Sony SS-CS3. 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.

Sony SS-CS3: $450.00 Discontinued
Pros: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Harmonic distortion remains reasonably low at moderate listening levels (86dB SPL) when high-pass filtered above 80-100Hz with a dedicated subwoofer. Front-ported design allows relatively close placement to front boundaries without excessive port occlusion.
Cons: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments. Irregular frequency response peaks and dips make automated receiver room correction difficult to equalize effectively. Poor low-frequency extension (F3 of 72Hz, F10 of 39Hz) for a floorstander, combined with rapid distortion escalation below 80Hz at higher SPLs (96dB+). Supertweeter driver adds crossover complexity without providing audible high-frequency benefit within the human hearing spectrum. Discontinued.
