JBL is stepping beyond traditional portable speakers with the launch of the BandBox series, a new category that blends a smart practice amp with a portable speaker. The JBL BandBox lineup introduces two variants, BandBox Solo and BandBox Trio, both built around on-device AI technology designed specifically for musicians. Instead of focusing on casual playback, JBL aims this range squarely at practice, rehearsal, and creative sessions, whether alone or with a group.

At the core of both models is an approach that treats music playback as something interactive rather than passive. With AI-powered stem separation, musicians can reshape songs in real time, removing or isolating vocals and instruments directly on the speaker. This positions the BandBox series as more than a Bluetooth speaker, but less cumbersome than a full studio setup.

AI Stem Separation as a Practice Tool

The defining feature of the BandBox series is Stem AI, an on-device vocal and instrument separation system. Unlike cloud-based solutions, this processing happens locally, without requiring an internet connection. Musicians can reduce or remove vocals, guitars, or drums from any Bluetooth-streamed track, turning existing songs into flexible backing tracks.

For practice scenarios, this means guitarists can mute the original guitar part and step into the mix themselves, while vocalists can rehearse without competing lead vocals. The real-time nature of the AI keeps the experience immediate, avoiding latency or workflow interruptions that often come with software-based solutions.

Portable Sound Tuned for Instruments

Both BandBox models are tuned for instrument-focused audio rather than pure consumer playback. JBL emphasizes balanced mids for guitars and vocals, supported by clear highs and controlled low-end response. This tuning makes the speakers equally suited for music playback, practice amplification, and small-scale performances.

While the Solo focuses on compact power, the Trio scales up significantly with a multi-driver configuration designed to fill larger spaces. In both cases, the goal is consistency, allowing musicians to hear their instrument clearly whether practicing quietly at home or playing with others.

BandBox Solo: Compact and Individual

JBL BandBox Solo is built for individual musicians who want a streamlined setup. With a single guitar or microphone input, it targets guitarists, singer-songwriters, and home players. The Solo supports amp modeling, pedal-style effects, and practice tools like a tuner and metronome through the JBL ONE app.

A built-in looper and pitch tools expand its creative potential, while USB-C connectivity allows direct recording into a DAW. The Solo is designed for portability and simplicity, making it easy to move from bedroom practice to outdoor writing sessions without additional gear.

BandBox Trio: Built for Groups and Jams

JBL BandBox Trio extends the concept to group playing. With four instrument inputs and a built-in four-channel mixer, it supports small bands, duos, or jam sessions. Physical controls on the unit reduce reliance on the app, offering faster adjustments during rehearsals.

The Trio also introduces a replaceable battery system for extended sessions and significantly higher output power. It can function as a monitor speaker or connect with additional PA systems, making it suitable for small gigs or collaborative setups where flexibility matters.

In the conclusion, JBL confirms that BandBox Solo and Trio will be available for pre-sale starting now, with shipping beginning March 1, 2026 via JBL and select retailers. Pricing is positioned to reflect their different use cases, with Solo aimed at personal practice and Trio at group performance.
