JBL BoomBox 3 Bluetooth Speaker – Brand New

Description

The JBL Boombox 3 is a premium portable Bluetooth speaker designed for loud, bass-heavy outdoor and indoor use. It delivers massive JBL Original Pro Sound with deeper bass than its predecessor (Boombox 2), thanks to a redesigned three-way audio system. It features a rugged, IP67-rated build that is fully dustproof and waterproof (submersible up to 1 meter for 30 minutes) and even floats in water, making it ideal for pool parties, beach outings, camping, or backyard gatherings.

Design and Build
The speaker retains the iconic cylindrical “boombox” silhouette but receives updates for a bolder look:
• Sturdy metal handle with comfortable orange silicone grips for easy carrying.
• Twin protective sidecaps.
• Durable, waterproof and dustproof fabric grille.
• Available in colors like black and camouflage (“Squad” variant).
Dimensions: 48.2 x 25.7 x 20.0 cm (19.0 x 10.1 x 7.9 inches)
Weight: 6.7 kg (14.7 lbs) — portable with the handle but hefty for long hikes.

Audio Performance
The Boombox 3 uses a 3-way speaker system:
• One racetrack-shaped subwoofer (189 x 114 mm) for deep, powerful bass.
• Two midrange drivers (2 x 80.9 x 80.9 mm / 2.75 inches).
• Two tweeters (2 x 20 mm / 0.75 inches) for clear highs.
Frequency response: 40 Hz – 20 kHz
Output power (RMS):
• AC mode: 1x 80W subwoofer + 2x 40W midrange + 2x 10W tweeter (total ~180W peak).
• Battery mode: Slightly reduced (1x 60W sub + 2x 30W mid + 2x 8W tweeter).
It produces a warm, bass-forward sound profile with good clarity for vocals and instruments. Reviews note it gets extremely loud with minimal distortion/compression at max volume, filling large spaces effectively. The sound is enjoyable for parties and various music genres, though the soundstage is somewhat narrow and directional. Sibilants (e.g., cymbals) can occasionally sound harsh, but the JBL Portable app offers a graphic EQ (or 3-band EQ) for customization.
It supports JBL PartyBoost, allowing you to pair it with other compatible JBL PartyBoost speakers for stereo or multi-speaker setups to amplify the party.

Who It’s For
The Boombox 3 excels as a high-performance party speaker for outdoor adventures or large gatherings where deep bass, volume, and weather resistance matter. It’s not the lightest or most compact option (heavier than some competitors), but its handle and ruggedness make it transportable in a car or for short carries. Some users note it’s pricey, but many praise the upgrade in bass depth, clarity, and overall power compared to the Boombox 2.45
