GB-001 Curtis, Portable Bluetooth Speaker with Cassette Player
With 104 watts of power delivered through four Hi-Fi speakers(two woofers for deep bass, two tweeters for crisp highs), the GB-001 turns any space into a full-on concert hall. It plays and records both Type I and Type II cassettes with a premium-grade mechanism, and an adjustable motor for ultra-stable playback.
But this boombox is more than a retro revival —it’s fully modern: Bluetooth 5.4, a rechargeable and replaceable battery, microphone input, fine-tuned sound controls (bass, treble, balance),backlit VU meters, and even an amp function for your guitar. Ready for a rap battle or a karaoke night? Plug in two wireless mics and put on a show.
RETRO LOOK, MODERN SOUND
The GB-001 isn't just a cassette player/recorder that rivals home cassette decks—it also delivers exceptional stereo sound with a full-spectrum stereo image, thanks to its separate left and right woofers and tweeters.
Whether you're listening to cassettes, using a wired connection, or streaming via Bluetooth, its four Hi-fi class loudspeakers (two powerful woofers for extended bass response and two soft dome tweeters for refined voices and treble) provide an impressive 104 Watts of total power output. That's enough to compete with the best connected speakers available.
But power is nothing without control. That's why we've included special features like dynamic power control to reduce distortion, refined equalization for a natural “We Are Rewind” sound signature, and a spatialization function for a wider, more immersive stereo experience.
RECORD & PLAYBACK AT ITS FINEST
This boombox features a top-of-the-line cassette deck mechanism, complete with a powerful, user-adjustable motor that includes internal speed regulation.
For recording and playing, it supports both Type I and Type II (chrome) cassettes with optimized biasing. To ensure low-noise recording and the best possible frequency response, it uses an active AC erasing head.
Like some of its predecessors, this boombox is equipped with two backlit VU meters, giving you control over playback and recording levels.
Finally, it includes a microphone input with adjustable level for live recordings.
ALL EYEZ ON YOU
The GB-001 reimagines the iconic 80s boombox with a sleek, neo-retro design that truly stands out.
Crafted from premium materials like brushed aluminum, it blends durability with modern aesthetics. It includes all the classic features of the era’s boomboxes, such as woofers, tweeters, a cassette player/recorder, VU meters, and a folding handle, all within a rectangular design.
Beneath its retro appearance, this "2.0" boombox is packed with modern technology, featuring Bluetooth 5.4 and a rechargeable, replaceable battery.
