DB1 Doublebass Round Bluetooth Speaker

Experience full-bodied bass and room-filling clarity with the only portable speaker that delivers 93 SPL, engineered to go wherever music takes you.

What Makes the DB1 Doublebass Different

Most wireless speakers make you choose. Sounds good, or carry easily. The DB1 doesn't accept that. It's built around a patented spherical enclosure with twin 5.2-inch passive radiators, pushes 40W through a 185mm chassis that fits in a backpack, and hits 93dB with bass that reaches 40Hz. That's the kind of low-end you feel somewhere around your sternum, not just register as "good bass".

Sound That Fills a Room

The sphere isn't just a design flex; it's acoustic engineering. A perfect sphere distributes audio evenly in every direction, cutting the internal reflections that give boxy speakers their characteristic coloration. UB+'s internal cavity works alongside the passive radiators to reinforce low frequencies without drawing more power to do it.
On paper: 40W woofer, 20W tweeter, flat response from 40Hz to 20kHz, 93dB max SPL. In practice, it holds up at volume without compressing the mids. That's rarer than spec sheets suggest.

Built for Outdoor and Indoor Use

IPX5 keeps rain and splashes from being a problem. The 4 × 2500mAh battery runs up to 20 hours on a charge, with Quick Charge bringing it back in 5 to 8 hours. Bluetooth 5.3 pairs fast and stays connected, and if you need a wired connection, there's a 3.5mm AUX and a USB-C port.

A cowhide leather strap handles one-hand transport. The optional anodized aluminum tripod stand elevates it for better projection when you want it in a fixed spot.

Stereo Mode and App Control
Pair two units via TWS (True Wireless Stereo), and you get actual left/right stereo channels, something most portable wireless speaker setups can't pull off convincingly. Latency is 75ms, which works fine for video.
The UB+ SEEK app (iOS and Android) unlocks EQ controls for bass and treble adjustments beyond the hardware buttons. Worth using if you move the speaker between different rooms.

What's in the Box

Single Speaker: DB1 Doublebass, USB-C cable, leather strap, strap fastener.
