What customers like about Demerbox DB2

  • Virtually indestructible, crush-proof build utilizing a genuine Pelican 1300 case
  • Fully waterproof and submersible when using the provided port plug, plus it floats in water
  • Exceptional battery life lasting over 40 hours on a single charge
  • Dual-purpose design offers dry internal storage to safe-keep valuables like keys, phones, and wallets
  • High volume output with loud, crisp sound that easily cuts through outdoor environmental noise
  • Power bank functionality allows charging of external devices via built-in USB ports
  • Sustainable design that is fully serviceable and repairable by the manufacturer
  • Strong, long-range Bluetooth connectivity that remains stable up to 100 feet
  • Multi-speaker pairing capability allows cascading multiple units together for a larger audio footprint

What customers don't like about Demerbox DB2

  • High retail price point makes it significantly more expensive than traditional portable speakers
  • Limited stereo separation and narrower soundstage due to the compact spacing of the internal drivers
  • Heavy-duty Pelican case clasps can be rigid and difficult for some users to pry open
  • Waterproof protection is completely negated whenever the case is open to use reverse-charging or auxiliary inputs
  • Sound profile leans heavily toward punchy bass frequencies, which may not appeal to audiophiles looking for flat, nuanced precision
  • Using the waterproof port plug slightly dampens the audio fullness compared to leaving the port open
  • The physical box lacks external mounting options or native integration with popular jobsite storage stack systems
  • Top-heavy or poorly packed internal contents can cause the unit to tip over easily

Verdict

The DemerBox DB2 is a highly rugged, portable Bluetooth speaker hand-built inside a crushproof military-spec Pelican 1300 case, delivering a maximum output power of 20 watts (11W RMS per channel) via two 3-inch aluminum-cone drivers and Class D audio circuitry that pushes up to 94 dB of sound. Its key pros include an exceptional 40+ hour battery life from its 2600mAh internal lithium-ion battery, a built-in USB port to charge mobile devices, secure dry internal storage for personal valuables, and an IP67 waterproof rating that allows it to float and withstand full submersion when using the included port plug. However, its primary cons are its hefty weight of 5.44 lbs compared to standard portable speakers, a high premium price tag, the requirement of line-of-sight to maintain its maximum 100-foot Bluetooth range smoothly, and the lack of smart app integrations or built-in radio functionality.
