The bottom is not something that is completely absent, but a person working with sound will not like these bottoms) maybe it will give 80-90, but not lower. They squeak normally, the volume is also enough for 20-30 squares, then it’s scary - the fart is still the same . At the exit to the rated power, the rear radiator heats up terribly, you can get burned. Of course, you can run it through a crossover, steer the frequencies, add an equalizer, dance with a tambourine and achieve something, but! After a week of use on background music (listened at low volume, sat quietly talking), the speaker farted and wheezed! A week! Dropped it off and got my money back. Do not want anymore.
