Short answer: the Jamo S7-15B. It ranks #53 of 168 bookshelf speakers by sound quality, rated 3.7/5, at $299; the Polk Signature Elite ES15 ranks #69, rated 3.5/5, at $299. Close enough in price that the sound-quality gap is the deciding factor.
What the Jamo S7-15B does well: Distinctive 7-degree tilted cabinetry, fabric-dome tweeter and a solid 4.52 raw local Spinorama score. The tradeoff: Despite the 45Hz snapshot extension metric, Jamo specifies a conservative 71Hz +/-3dB bandwidth, so deep bass needs support.
The Polk Signature Elite ES15 is the deeper-bass choice. A compact 5.25-inch passive bookshelf speaker designed for hi-res stereo music and home theater surrounds. Its bass reaches about 58Hz before falling 3dB, against 69.6Hz for the Jamo S7-15B. The catch: The 5.25-inch woofer has lower sensitivity (88dB) and less low-bass extension than its larger sibling, the 6.5-inch Polk Signature Elite ES20.
Buy the Jamo S7-15B. It is rated higher for sound quality than the Polk Signature Elite ES15 at the same price, so only choose the other one for a particular feature it does better.

Same family: the Jamo S7-17B (larger bookshelf, estimated 3.7/5) and the Jamo S7-25F (floorstanding, estimated 3.7/5).
Pros: Distinctive 7-degree tilted cabinetry, fabric-dome tweeter and a solid 4.52 raw local Spinorama score. With a subwoofer it reaches 6.66, while the compact format and magnetic grilles suit living-room use. Measured bass extension of 69.6Hz (-3dB).
Cons: Despite the 45Hz snapshot extension metric, Jamo specifies a conservative 71Hz +/-3dB bandwidth, so deep bass needs support. The four-ohm load and modest 86.3dB sensitivity require a capable amplifier.

Polk Signature Elite ES15: $299.00 per pair Passive Amazon eBay
Older model: the Polk Audio Signature S15 (ranked higher, rated 3.7/5). See every Polk Signature generation.

Pros: A compact 5.25-inch passive bookshelf speaker designed for hi-res stereo music and home theater surrounds. Features a 1-inch Terylene dome tweeter capable of extending up to 40kHz alongside a 5.25-inch mica-reinforced polypropylene woofer and Polk’s patented Power Port bass-reflex technology. Erin’s Audio Corner Klippel NFS testing demonstrates excellent directivity control and smooth listening-window response with very low distortion. Power Port reduces turbulent air noise and provides clean low-frequency reinforcement down to approximately 58Hz. Measured bass extension of 58Hz (-3dB).
Cons: The 5.25-inch woofer has lower sensitivity (88dB) and less low-bass extension than its larger sibling, the 6.5-inch Polk Signature Elite ES20. A dedicated subwoofer is recommended for home theater action dynamics and full-range orchestral playback.
