Portable Bluetooth speaker with subwoofer

The SOWO Surgeboom 3 is a wireless audio component built around Bluetooth 5.0 for instant pairing with phones, computers and laptops. Its IP67 rating makes it fully dustproof and waterproof, so it suits outdoor use at the beach, by the pool or in the bathroom. The one-piece injection-moulded body and mesh grille are designed to withstand rough handling while travelling.

Simple wireless setup with light control

Pairing is handled entirely through Bluetooth 5.0; no cables or drivers are required. The only common issue is forgetting that the RGB radiator lights default to on, which drains the battery faster; they can be switched off via the onboard controls when not wanted. The rugged IP67 shell means sand or water ingress will not interrupt playback.

32% bass boost via BASSBOOM technology

The deciding specification is the DSP-driven BASSBOOM enhancement that raises low-frequency output by 32% over the base tuning. Dual power diaphragms keep total harmonic distortion below .5%, while two passive radiators and dedicated tweeters deliver the richer tone that separates this model from basic portable speakers.

Questions about this item

How can I verify the subwoofer is performing within the stated distortion limit after setup?

Play bass-heavy audio at high volume; the dual power diaphragms are engineered to keep total harmonic distortion below .5% so the low end should stay clean without audible cracking.

What accessories are included in the box versus what must be purchased separately?

The speaker ships as a single unit with its integrated subwoofer, passive radiators and RGB lighting built in; no extra cables, mounts or batteries are listed as included.

Which colour option should I choose among Black+Blue, Pink and Red?

All three finishes share identical IP67 waterproofing, Bluetooth 5.0 connectivity and BASSBOOM tuning, so pick the hue that best matches your style or riding gear.
