You can find in the reviews something about low volume. From my own experience, I realized that it depends on the connection method and the device. For example, a phone with a minijack is 2 times quieter than the same phone with BT. And the minijack macbook plays the full power of the speakers. In the living room, 25m² sounds great, the speakers are 3 meters apart. The cable from the kit for connecting the master speaker to the secondary speaker is 5m
