Enjoy impressive audio from the UB+ dB1 DOUBLEBASS spherical speaker. Producing audiophile-quality sound from its 4.5″ woofer—with a 90 mm magnet—and 28 mm tweeter, it also has a pair of 5.2″ passive radiators and TWS. The passive radiators are 3 times larger than the speaker drive and produce pulsating movements known as symmetrical oscillation. Delivering low-latency and low-bass sound, it has a super wide 40 Hz to 20 kHz frequency response and a 93 dB sound pressure level. Use Bluetooth 5.3 to synchronize up to 8 units for surround sound. Moreover, its carefully designed details and audio performance deliver. Additionally, it has 2 discreet attachment points for a carry strap. That makes it easy to take it with you anywhere you go. Alternatively, you can mount it on a sleek tripod for in-home use. With a waterproof exterior, it can handle accidental spills or splashes from the pool.
