Short answer: the Focal 100 OD6 on measured sound quality, the Polk Audio Atrium 4 on price. The Focal 100 OD6 ranks #4 of 13 outdoor speakers, rated 3.7/5, at $698. The Polk Audio Atrium 4 ranks #11, rated 2.6/5, at $117, $581 cheaper.
The Focal 100 OD6 is the better-sounding pick. Modern outdoor successor to the Chorus OD 706 V featuring Focal’s signature 6.5” Polyglass mid-bass woofer and inverted aluminum dome tweeter in an updated IP66-certified high-density polypropylene enclosure. The tradeoff: Sealed cabinet acoustic design limits low-frequency bass punch, rolling off below 65Hz (-3dB) and 55Hz (-6dB) without boundary wall assistance.
The case for the Polk Audio Atrium 4: Extremely compact, lightweight (1.63 kg), and affordable outdoor pair with Speed-Lock quick mounting bracket. The tradeoff: Small 4.5” driver restricts low-end performance; bass extension drops steeply past 98Hz (-6dB) with little acoustic energy below 100Hz.
Buy the Focal 100 OD6 when sound quality outweighs the price for you, and the Polk Audio Atrium 4 when the price outweighs sound quality instead.

Focal 100 OD6: $698 per pair Estimated Crutchfield eBay
Older model: the Focal Chorus OD 706 V (ranked higher, rated 3.7/5).
Pros: Modern outdoor successor to the Chorus OD 706 V featuring Focal’s signature 6.5” Polyglass mid-bass woofer and inverted aluminum dome tweeter in an updated IP66-certified high-density polypropylene enclosure. Excellent weatherproofing protects against intense rain and UV exposure, while the reinforced notched aluminum bracket allows 180° rotation for flexible horizontal or vertical mounting.
Cons: Sealed cabinet acoustic design limits low-frequency bass punch, rolling off below 65Hz (-3dB) and 55Hz (-6dB) without boundary wall assistance. Full laboratory-grade Klippel NFS Spinorama directivity curves have not yet been published, so preference scores are estimated from the measured Chorus predecessor.

Polk Audio Atrium 4: $117.00 per pair Amazon eBay
Pros: Extremely compact, lightweight (1.63 kg), and affordable outdoor pair with Speed-Lock quick mounting bracket. Clean build quality that easily survives harsh rain and sun exposure. Smooth dispersion pattern (+60/-70 degrees horizontal). Measured bass extension of 112.8Hz (-3dB).
Cons: Small 4.5” driver restricts low-end performance; bass extension drops steeply past 98Hz (-6dB) with little acoustic energy below 100Hz. Notable mid-treble shelf gives it a forward, bright presentation and yields a low 1.46 preference score.
