Cube EX Street - Battery-Powered Stereo Amplifier

The Boss CUBE Street EX is the ultimate grab-and-go amplifier for musicians who perform beyond the confines of a traditional stage. Designed for buskers, street performers, travelling musicians and mobile events, this battery-powered stereo amplifier delivers impressive power, versatility and professional sound quality wherever you play.

Despite its compact and portable design, the CUBE Street EX packs serious punch. With 50 watts of stereo power available when running on AC and adjustable power modes for battery operation, it’s capable of filling outdoor spaces with clear, full-bodied sound. Whether you’re performing on Grafton Street, playing a small outdoor event, or rehearsing in a park, this amp is built to project.

The CUBE Street EX features two 8-inch woofers and two tweeters, creating a wide stereo field with excellent clarity and low-end response. Vocals, acoustic instruments and backing tracks all come through cleanly, making it ideal for solo performers and small ensembles.

Connectivity is where this amp really shines. You get four independent channels, allowing you to plug in microphones, guitars, keyboards or backing tracks simultaneously. Dedicated vocal channels include built-in reverb and EQ, while guitar channels feature Boss COSM amp modelling and effects, letting you dial in great tones without extra pedals.

For performers who rely on backing tracks, the aux input makes it easy to connect phones or media players, while the line outputs allow you to send your mix to a PA system or recording setup when needed.

One of the biggest advantages of the CUBE Street EX is its portability. Running on eight AA batteries, it can deliver hours of performance depending on the selected power mode. The lightweight design and optional wireless capability make it perfect for musicians on the move.

You can even link two CUBE Street EX units together for a wider stereo spread and more power — ideal for larger outdoor performances.

At Musicmaker, the CUBE Street EX has become a favourite among buskers and acoustic performers across Ireland. It’s reliable, flexible and genuinely powerful for a battery-powered amp.

If you’re searching for a battery-powered busking amplifier in Ireland that delivers professional sound and flexible connectivity, the Boss CUBE Street EX is one of the best options available.
