BOSS CUBE Street II Battery-Powered Amplifier

Wherever you perform, great sound and projection are essential to engage your audience. The BOSS CUBE Street II gives you everything you need to perform with confidence—anywhere, anytime.
Evolved from the best-selling Roland CUBE Street and now proudly branded BOSS, this portable, battery-powered amplifier delivers rich stereo sound, dual-channel flexibility, and onboard effects designed for musicians, performers, and presenters alike.

With built-in vocal harmony, looping, and Bluetooth® expansion options, the CUBE Street II is your all-in-one performance companion for busking, street gigs, livestreaming, and public speaking.

Portable Power and Performance

The CUBE Street II delivers 10 watts of stereo power (5 W x 2) through two custom 6.5-inch speakers, providing clear, full-range sound in any environment.
Its durable ABS injection-molded cabinet is lighter than ever—just 4.4 kg—while delivering excellent projection for outdoor or indoor use.

• 10 watts total output (5 W + 5 W)

• Dual 6.5-inch speakers for crisp, clear stereo sound

• Lightweight and durable ABS enclosure (4.4 kg / 9 lb 12 oz)

• Angled face design for improved sound projection

• Eco mode extends battery life for longer sessions

Dual Channels for Versatile Setups

Two independent channels give you complete flexibility for microphones, guitars, keyboards, or line instruments.

• Mic/Instrument Channel: XLR/TRS combo input with 3-band EQ, reverb, and vocal harmony

• Guitar/Mic Channel: ¼-inch input with nine amp types, 3-band EQ, chorus/delay, reverb, and tuner

You can easily balance vocals and instruments for a professional live sound without any external gear.

Built-In Harmony, Looper, and Effects

Enhance your performance with creative tools designed for live use. The harmony function automatically generates natural vocal harmonies based on your guitar chords or a set key. The built-in looper provides up to 45 seconds of stereo recording—ideal for layering parts and building backing loops on the spot.

• Harmony effect with three modes: Unison, High, and Higher

• Looper with up to 45 seconds of stereo recording

• Onboard chorus, delay, and reverb effects

• Optional footswitch control for hands-free looping and harmony activation

Connectivity for Every Situation

The CUBE Street II supports a wide range of connection options for both live performance and recording.
Use the i-CUBE Link or USB connection to record or livestream directly to a computer or mobile device, or connect to a house PA for expanded sound.

• USB audio output for recording or streaming
