Sony SRS XB43 Specs, Specifications

Here, we list Sony SRS XB43 Extra Bass Bluetooth speaker specs.  Firstly, these specifications cover the unit’s length, width, weight, battery recharge time, output power, and music play time per charge.  We also include the frequency response, driver size, Bluetooth support details et al.

Secondly, it’s clear from the published specs, that the Sony SRS XB43 released in May of 2020, sounds pretty good for its size. E.g. It plays loud enough for small parties on patios, swimming pools, et al, with its roughly sixteen (16) watts RMS of total audio power.

Plus, even at loudest volume, the lithium ion battery can last from four (4) to twenty-four (24) hours per recharge depending on the party light setting, surrounding temperature, and program content.  Indeed, the specs certainly do not mislead as to the great features Sony put into this IPX7 water resistant Bluetooth speaker.
