These sit in different size classes, so this is not a straight ranking comparison. The Turtlebox Grande ranks #78 of 100 boombox speakers by sound quality at $730; the Soundboks Mix ranks #33 of 49 party speakers by sound quality at $799.
The Turtlebox Grande is a rugged boombox built for boats and job sites. Its 10-inch woofer and titanium tweeter play in stereo in an IP67, crush-proof shell, its 158Wh battery is rated for about 25 hours, and it links with other Turtleboxes in party mode. Its bass is shallow for that woofer, falling 10dB around 55Hz, and it charges only from its barrel-plug adapter.
The Soundboks Mix is a party speaker with a swappable battery. Its 10-inch woofer and horn tweeter are efficient, it claims 40 hours at mid volume, and its battery fast-charges over USB-C and can be swapped out. TeamUp links up to five other Soundboks speakers. It is rated IP65, a step below the Grande, and can sound bright in the treble.
Buy the Turtlebox Grande ($730) for a boombox speaker; the Soundboks Mix ($799) suits a party speaker instead.
