Short answer: the Audio Pro C5 MkII. It ranks #1 of 17 powered desktop speakers by sound quality, rated 4.5/5, at $300. The Sonos Era 100 ranks #13, rated 3.6/5, at $219, $81 cheaper, which does not close the gap in sound quality.
Why pick the Sonos Era 100: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. The catch: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments.
Why pick the Audio Pro C5 MkII: At 2.4 kg, Audio Pro C5 MkII combines 4” woofer, 2x 0.75” tweeters with Bluetooth, Wifi, RCA. The catch: Bass is limited by its 50Hz - 20kHz (Manufacturer specified) specification.
Buy the Audio Pro C5 MkII. It is rated higher for sound quality, and the $81 you would save on the Sonos Era 100 does not close the gap.

The Two Speakers In Full
Sonos Era 100: $219.00 each Amazon eBay
Pros: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. Alexa is built in with a far-field mic, and it ties into the wider Sonos S2 app ecosystem for multi-room audio.
Cons: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments. There’s no Google Assistant, the USB-C line-in needs a separately purchased adapter, and there’s no battery.
