Polk Audio BOOM Swimmer Duo

Waterproof portable speaker system with wireless connection and speakerphone function. Protected from moisture ingress according to the IPx7 standard, it is able to maintain performance even under water (up to 30 minutes at a depth of up to 90 cm). Designed for use in bathrooms, showers, on the beach or in outdoor areas exposed to atmospheric precipitation. The manufacturer is positioned as a model of the middle price category, designed for the widest possible range of potential buyers.

It consists of a hardware unit and a screw-in replacement mount. It comes with two mounting options: a flexible leg that can be fixed on a pipe / hook / bar / bicycle frame and a suction cup designed for mounting on even and smooth surfaces, such as glass. In the second case, a flat and smooth surface can play the role of an additional sound emitter, enhancing the acoustic effect.

The nominal power of the Polk Audio BOOM Swimmer Duo speaker system is 2.5 W, which is quite enough for personal use. According to the manufacturer, the frequency range from 240 to 16000 Hz is reproduced. Connecting to a smartphone or tablet is done using the bluetooth wireless interface, which is also responsible for the hands-free function that turns the speaker into a bluetooth headset. To connect an analogue signal, there is a line input AUX IN. The capacity of the built-in lithium-ion battery is enough for 4.5-5 hours of battery life at maximum volume or 8 hours of moderate use.
