These are not really the same size class, and that is the honest framing here. The JBL Partybox Ultimate 2 ranks #2 of 13 large party speakers by sound quality at $1,799.95; the Soundboks 4 ranks #10 of 17 battery-powered PA speakers by sound quality at $1,199.
Why pick the JBL Partybox Ultimate 2: A huge mains-powered party speaker with very loud output, deep bass, Wi-Fi streaming and inputs for mics and guitar. The tradeoff: Its deep bass doesn’t hit as hard as the price suggests.
The Soundboks 4 is the battery-powered choice. A very loud battery party speaker with two 10 inch woofers and a removable 40 hour battery for big outdoor gatherings. Its battery is rated for 40 hours, while the JBL Partybox Ultimate 2 needs an outlet. The tradeoff: Not as neutral or as deep of bass as the above Partyboxes.
Buy the JBL Partybox Ultimate 2 at $1,799.95 if you want a large party speaker. Buy the Soundboks 4 at $1,199 if you want a battery-powered PA speaker instead.
