Short answer: a tie on sound quality. Both are rated 3.8/5 (#161 and #149 of 226 floorstanding speakers) at nearly the same price ($1,999.98 vs $1,998), so choose on features and fit.

The case for the KLH Model Four: A slim floorstanding member of KLH’s Model collection, with an 8” woofer and the same 4” midrange and 1” aluminum tweeter as the measured KLH Model Five (4.76 Spinorama preference score). The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured KLH Model Five.
The case for the SVS Prime Pinnacle: 3-way floorstanding tower featuring triple 6.5-inch woofers, each in its own discrete rear-ported internal sub-enclosure with individual 2-inch ports. The catch: At 1044mm tall and 57.1 lbs (25.9 kg) each, this tower requires space and clearance for its three rear-firing ports to prevent boundary room mode loading.
Buy the KLH Model Four or the SVS Prime Pinnacle on features: they are rated the same for sound quality at close to the same price.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KLH Model Four 3.4 to 4.1; SVS Prime Pinnacle 3.6 to 4.0). Treat this verdict as provisional.

KLH Model Four: $1,999.98 per pair Estimated Amazon eBay
Same family: the KLH Model Three (bookshelf, estimated 3.8/5), the KLH Model Five (larger floorstanding, ranked higher, rated 4/5) and the KLH Model Seven (larger floorstanding, ranked higher, estimated 4/5).
Pros: A slim floorstanding member of KLH’s Model collection, with an 8” woofer and the same 4” midrange and 1” aluminum tweeter as the measured KLH Model Five (4.76 Spinorama preference score). The sealed cabinet is only 210mm deep and can sit 6 inches from a wall. KLH rates it 46Hz to 20kHz (±3dB) and 35Hz at -10dB.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured KLH Model Five. Free-field sensitivity is 85dB and the impedance falls to 3.5 ohms at 120Hz, so it needs more amplifier power than its size suggests.
