Short answer: the Marshall Acton III. It ranks #11 of 28 powered desktop speakers by sound quality, rated 3.7/5, at $298.99. The Klipsch The One Plus ranks #7, rated 3.4/5, at $239.99, $59 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Marshall Acton III: At 6.3 lbs (2.85 kg), Marshall Acton III combines 4” (midrange/woofer), 1x 4” midrange, 2x 0.75” Dome tweeters with Bluetooth, Aux. The tradeoff: Bass is limited by its 45Hz to 20kHz (Manufacturer specified) specification.
Why pick the Klipsch The One Plus: The One Plus updates Klipsch’s tabletop Heritage speaker with Bluetooth 5.3, Broadcast Mode for linking 10+ compatible units, and USB-C playback with 10W reverse charging. The catch: Bass drops steeply below 55Hz and the single-cabinet design delivers limited stereo soundstage width.
Buy the Marshall Acton III. It is rated higher for sound quality, and the $59 saving on the Klipsch The One Plus is not enough to make up the difference.
Worth knowing: the Klipsch The One Plus has not been measured yet. Its rating is estimated from related models, with a likely range of 3.2 to 3.6, so treat this verdict as provisional.

Klipsch The One Plus: $239.99 each Amazon $239.99 eBay
Older model: the Klipsch The One II (rated 3.3/5). See every Klipsch The One and The Three generation.
Same family: the Klipsch The Three Plus (larger model, rated 3.4/5).
Pros: The One Plus updates Klipsch’s tabletop Heritage speaker with Bluetooth 5.3, Broadcast Mode for linking 10+ compatible units, and USB-C playback with 10W reverse charging. It features a biamplified 2.1 acoustic system rated at 60W continuous power driving two 2.25-inch full-range drivers and a 4.5-inch high-excursion woofer with dual opposing 4.5-inch passive radiators, delivering solid output down to a specified 55Hz (-3dB). App support via Klipsch Connect provides customizable three-band EQ.
Cons: Bass drops steeply below 55Hz and the single-cabinet design delivers limited stereo soundstage width. It requires AC power with no internal battery, lacks on-device track skip/pause controls, and omits the optical and phono inputs found on its larger sibling, the Klipsch The Three Plus.
