These sit in different size classes, so this is not a straight ranking comparison. The Amazon Echo Studio 2nd Gen ranks #2 of 9 powered desktop speakers by sound quality at $219.99; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.
The case for the Amazon Echo Studio 2nd Gen: SoundGuys called it the best-sounding Amazon speaker they have tested, scoring it 7.8 of 10. The tradeoff: SoundGuys still marked it down on Value (4.0 of 10) given the $219.99 list price, and it is explicitly not true left-right stereo from one cabinet, so a stereo pair is needed for real width in a larger room.
The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the Amazon Echo Studio 2nd Gen at $219.99 for a powered desktop speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.

The Two Speakers In Full
Amazon Echo Studio 2nd Gen: $219.99 each Amazon eBay
Pros: SoundGuys called it the best-sounding Amazon speaker they have tested, scoring it 7.8 of 10. A 3.75-inch high-excursion woofer and three 2.25-inch full-range drivers fire left, right and upward, giving a real sense of width and instrument separation from a single enclosure, with vocals sitting forward and clean cymbals even at moderate volume. It supports Dolby Atmos and spatial audio on compatible content, stays distortion-free up to about 70% volume, and includes a built-in Zigbee, Matter and Thread smart home hub plus a 3-band EQ with a Dolby Virtualizer toggle.
Cons: SoundGuys still marked it down on Value (4.0 of 10) given the $219.99 list price, and it is explicitly not true left-right stereo from one cabinet, so a stereo pair is needed for real width in a larger room. There are no wired audio inputs of any kind and no battery, so it must stay plugged in, and Bluetooth is limited to the SBC codec. Voice recognition wasn’t perfectly reliable in testing, occasionally playing the wrong track for a specific artist-title request.
