Short answer: the Polk T50 for value, the SVS Ultra Evolution Pinnacle if budget is not the point. The Polk delivers pretty deep bass for the money, but it has a 5dB peak at 1kHz and a top end 4dB bright from 11kHz up. The Pinnacle is a large time-aligned curved-baffle tower that is far from linear itself, with a dip-then-peak around 2-3kHz that makes vocals shouty. At $2,499 against $498, the gap buys cabinet construction, not a flatter response.
The case for the SVS Ultra Evolution Pinnacle: 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. The tradeoff: 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 Polk T50. Both are rated the same for sound quality, and it costs $2,001 less than the SVS Ultra Evolution Pinnacle.

The Two Speakers In Full
SVS Ultra Evolution Pinnacle: $2,499.00 per pair Amazon SVS eBay
Pros: Flagship three-way tower with a diamond-coated tweeter, dual midranges and four force-balanced 8-inch woofers. Erin measured exceptional 27Hz extension, broad roughly +/-75-degree horizontal coverage, an 88.1dB sensitivity and a 4.91 preference score even without a subwoofer. Measured bass extension of 41.0Hz (-3dB).
Cons: The 5.25-to-8-inch transitions and complex array do not produce class-leading smoothness: 0.184 on-axis, 0.226 predicted in-room and 3.64 directivity-index consistency. At 96.7 pounds each, these are difficult to position, and their Q of 1.25 indicates some bass emphasis. A dip in the upper midrange followed closely by a peak around 2 to 3kHz gives vocals a shouty, forward quality that toe-out alone does not resolve.

Polk T50: $498 per pair Amazon eBay
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.
