JBL Boombox 4 Portable Bluetooth Speaker

The JBL Boombox 4 represents a significant evolution in portable audio, prioritizing powerful sound, extended durability, and modern features. Its core specifications reveal a true powerhouse designed for both indoor and massive outdoor gatherings.

The Boombox 4 features a redesigned 7-driver system, consisting of two 5-inch woofers, two 0.75-inch tweeters, and three passive radiators (two circular on the sides and one racetrack on the back). This configuration delivers a massive audio output of up to 210W RMS in AC mode ($2 \times 65W$ RMS for woofers, $2 \times 40W$ RMS for tweeters) and a still-powerful 200W RMS in battery mode (a substantial 50% increase in battery power output over its predecessor). It boasts an extended low-frequency response down to 37Hz for deep, chest-thumping bass and supports a frequency range of $37 \text{ Hz} – 20 \text{ kHz}$.

A key technological addition is AI Sound Boost, a real-time audio analysis and adjustment system that maximizes power while minimizing distortion, ensuring clear sound even at maximum volume. Users can also select between two dedicated Bass Boost modes—Deep Bass for a rich, full low end, or Punchy Bass for a tighter, more energetic sound.

 Battery Life and Endurance

The speaker is powered by a high-capacity 99.02 Wh Li-ion battery pack, offering up to 28 hours of continuous music playback at moderate levels. A feature called Playtime Boost can extend this to an impressive 34 hours under specific conditions. Crucially, the Boombox 4 features a user-replaceable battery design (battery sold separately), significantly enhancing the speaker’s longevity and product life. Charging is accomplished via the AC input, achieving a full charge in approximately 3 hours.

Connectivity and Durability

The Boombox 4 adopts Bluetooth 5.4 for enhanced stability, range, and efficiency. Its most notable connectivity upgrade is the transition from the proprietary PartyBoost system to the industry-standard Auracast™. Auracast allows for the connection of an unlimited number of compatible JBL speakers for a synchronized, scalable sound system, including creating a true stereo pair. Additionally, the USB-C port now supports lossless audio playback when connected to a compatible source, catering to audiophiles.

Built for the elements, the speaker carries an IP68 rating, confirming full protection against both dust ingress and water submersion, making it perfectly suited for beach, pool, or any rugged outdoor environment.
