Short answer: the Ascend Acoustics Sierra Titan Tower. Both are rated 4.4/5 for sound quality (#45 and #53 of 226 floorstanding speakers), and the Ascend Acoustics Sierra Titan Tower costs $2,998 against $5,599.98 for the Paradigm Founder 100F, and with sound quality even, the cheaper one is the better buy.
The case for the Ascend Acoustics Sierra Titan Tower: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. The tradeoff: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier Ascend Acoustics ELX Ribbon Tower.
What the Paradigm Founder 100F does well: 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 tradeoff: Significant physical size and price tier.
Buy the Ascend Acoustics Sierra Titan Tower. Both are rated the same for sound quality, and it costs $2,601.98 less than the Paradigm Founder 100F.
About the ratings: the Paradigm Founder 100F’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.2 to 4.6, so this verdict could change once it is measured.

Ascend Acoustics Sierra Titan Tower: $2,998 per pair Ascend Acoustics eBay
Same family: the Ascend Acoustics Sierra 1 v2 (smallest bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-2EX V2 (bookshelf, rated 4.3/5), the Ascend Acoustics Sierra-LX (largest bookshelf, rated 4.3/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5). See every Ascend Sierra generation.
Pros: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. The bass alignment Q of 0.72 keeps the low end reasonably well controlled. Backed by the same 7 year parts and labor warranty and hand matched +/-1.5dB pairs, each shipped with its own production line frequency response printout. Measured bass extension of 58.6Hz (-3dB).
Cons: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier Ascend Acoustics ELX Ribbon Tower. Sound power response falls off more steeply above the crossover than the ribbon version, so off axis and in room treble energy rolls off faster. Ascend sells direct only, with no dealer network or third party retailers for an in person audition.

Paradigm Founder 100F: $5,599.98 per pair Estimated Audio Advice eBay

Cons: Significant physical size and price tier. On-axis treble maintains the energetic Founder voicing, rewarding parallel or gentle toe-in room placement.
