Short answer: the Marshall Stanmore III. It ranks #6 of 19 powered desktop speakers by sound quality, rated 3.8/5, at $345.99. The Bose Lifestyle Ultra Speaker ranks #12, rated 3.7/5, at $299, $46.99 cheaper, which does not close the gap in sound quality.
Why pick the Marshall Stanmore III: At 4.4 kg, Marshall Stanmore III combines 5” (midrange/woofer), 1x 5” midrange, 2x 0.75” Dome tweeters with Bluetooth, RCA, Aux. The tradeoff: Bass is limited by its 45Hz - 20kHz (Manufacturer specified) specification.
Why pick the Bose Lifestyle Ultra Speaker: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. The tradeoff: RTINGS lists sub-par directivity as its main weakness, and reviewers agree a single unit sounds narrow from side to side, so it works best as a stereo pair.
Buy the Marshall Stanmore III. It is rated higher for sound quality, and the $46.99 saving on the Bose Lifestyle Ultra Speaker is not enough to make up the difference.

Bose Lifestyle Ultra Speaker: $299.00 each Amazon eBay
Pros: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. Stuff gave it the edge over the Sonos Era 100, and TechRadar called its tonal balance fairly neutral, with tight bass control and high detail. Alexa, including Alexa+, is built in, and RTINGS found its microphones picked up commands easily from across a noisy room. It streams over AirPlay 2, Google Cast, Spotify Connect and Bluetooth 5.3, keeps a 3.5mm aux input that the Era 100 lacks, and two units can be stereo paired or used as rear surrounds with the Lifestyle Ultra Soundbar.
Cons: RTINGS lists sub-par directivity as its main weakness, and reviewers agree a single unit sounds narrow from side to side, so it works best as a stereo pair. Deep bass is limited: Engadget found the low end restrained and preferred the Denon Home 200’s sound, Stuff noted it can’t separate sub-bass from the bassline and that DSP pulls bass back at maximum volume, and TechRadar heard a slight toothiness in the treble that needed EQ to calm. The EQ is only bass, mid and treble with no automatic room calibration. Bose warns the aux and Bluetooth inputs add lip sync delay for TV use, it has no battery or IP rating, and both SoundGuys and Engadget needed several restarts to get stereo pairing working.
