Short answer: the Wharfedale Diamond 12.4i. It ranks #107 of 226 floorstanding speakers by sound quality, rated 4.2/5, at $1,498; the SVS Ultra Evolution Tower ranks #112, rated 4.1/5, and costs $2,998, so there is not much of a tradeoff to weigh.
The case for the Wharfedale Diamond 12.4i: The largest tower in Wharfedale’s 2025 Diamond 12i range and the update of the Wharfedale Diamond 12.4, keeping its twin 6.5” Klarity woofers and 2.5-way layout in a 40.8L cabinet with a refined port and damping. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the SVS Ultra Evolution Tower: Slim 3-way floorstanding tower with time-aligned curved baffle geometry, a 1-inch diamond-coated aluminum dome tweeter, dual 4.5-inch glass-fiber midranges, and quad force-balanced 5.25-inch woofers. Watch for: 87dB sensitivity is moderate, demanding solid amplification with at least 100W per channel to reach reference home theater volume levels.
Buy the Wharfedale Diamond 12.4i. It is rated higher for sound quality than the SVS Ultra Evolution Tower and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Wharfedale Diamond 12.4i 3.9 to 4.5; SVS Ultra Evolution Tower 3.9 to 4.3). Treat this verdict as provisional.

Wharfedale Diamond 12.4i: $1,498 per pair Estimated Music Direct eBay
Older model: the Wharfedale Diamond 12.4 (ranked lower, estimated 4.1/5). See every Wharfedale Diamond generation.
Same family: the Wharfedale Diamond 12.0i (smaller bookshelf, estimated 3.2/5), the Wharfedale Diamond 12.1i (larger bookshelf, estimated 4/5), the Wharfedale Diamond 12.3i (smaller floorstanding, ranked lower, estimated 4/5) and the Wharfedale Diamond 12.Ci (center, estimated 3.6/5).
Pros: The largest tower in Wharfedale’s 2025 Diamond 12i range and the update of the Wharfedale Diamond 12.4, keeping its twin 6.5” Klarity woofers and 2.5-way layout in a 40.8L cabinet with a refined port and damping. Rated to 40Hz (±3dB) at 89dB sensitivity, it fills a larger room without a subwoofer.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. The changes over the 12.4 are refinements rather than new drivers, and at 22.4 kg per speaker it needs room to breathe away from walls.

SVS Ultra Evolution Tower: $2,998 per pair Estimated Amazon SVS eBay
Same family: the SVS Ultra Evolution Nano (smaller bookshelf, estimated 3.9/5), the SVS Ultra Evolution Bookshelf (larger bookshelf, estimated 4/5), the SVS Ultra Evolution Titan (larger floorstanding, ranked higher, estimated 4.2/5), the SVS Ultra Evolution Pinnacle (larger floorstanding, ranked lower, rated 3.8/5), the SVS Ultra Evolution Center (center, estimated 4.1/5) and the SVS Ultra Evolution Elevation (surround, estimated 3.8/5). See every SVS Ultra and Ultra Evolution generation.
Pros: Slim 3-way floorstanding tower with time-aligned curved baffle geometry, a 1-inch diamond-coated aluminum dome tweeter, dual 4.5-inch glass-fiber midranges, and quad force-balanced 5.25-inch woofers. Extends down to 30Hz (±3dB) with 87dB sensitivity and 6 ohm impedance in a more compact footprint than the Titan.
Cons: 87dB sensitivity is moderate, demanding solid amplification with at least 100W per channel to reach reference home theater volume levels. Dual rear-firing ports require clearance from boundaries to avoid bass bloat.
