Short answer: the KEF R7 Meta. It ranks #19 of 226 floorstanding speakers by sound quality, rated 4.6/5, at $5,999.98. The Paradigm Founder 100F ranks #53, rated 4.4/5, at $5,599.98, $400 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the KEF R7 Meta: Mid-sized 3-way floorstander in KEF’s high-end R series. The tradeoff: Dips to 3.2 ohms minimum impedance, requiring an amplifier capable of driving 4-ohm loads with stability.
The case for the Paradigm Founder 100F: Dedicated isolated 6-inch AL-MAG midrange driver and triple 7-inch CARBON-X woofers yield excellent dynamic headroom and bass authority down to 26Hz. The catch: Significant physical size and price tier.
Buy the KEF R7 Meta. It is rated higher for sound quality, and the $400 you would save on the Paradigm Founder 100F does not close the gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KEF R7 Meta 4.4 to 4.8; Paradigm Founder 100F 4.2 to 4.6). Treat this verdict as provisional.

Older model: the KEF R7 (ranked lower, estimated 4.2/5). See every KEF R Series generation.
Same family: the KEF R3 Meta (bookshelf, rated 4.6/5), the KEF R5 Meta (smaller floorstanding, ranked higher, rated 4.6/5), the KEF R11 Meta (larger floorstanding, ranked lower, rated 4.4/5), the KEF R2 Meta (smaller center, rated 4.3/5) and the KEF R6 Meta (larger center, rated 4.2/5).
Pros: Mid-sized 3-way floorstander in KEF’s high-end R series. Combines a 12th-generation Uni-Q array (1-inch vented aluminum dome with MAT and 5-inch aluminum midrange) with dual 6.5-inch hybrid aluminum bass drivers in an extensively braced, constrained-layer damped cabinet. Delivers 48Hz to 28kHz (±3dB) with 27Hz in-room extension, 88dB sensitivity, and under 0.5% THD across the midrange.
Cons: Dips to 3.2 ohms minimum impedance, requiring an amplifier capable of driving 4-ohm loads with stability. Rear-firing port requires boundary breathing room to maintain tonal neutrality.
