This little speaker has a very good range of higher frequencies. There is not much room for bass resonance but it is a kicker for this small sizea. The packaging was a little bit damaged but the Item is good. Reaches from 200Hz to 12Hz and from 8000Hz to 20000Hz. In loudest settings this speaker generates 80 when measured from 30cm away. I would recommend the product and seller.
Excellent column, with excellent sound. The material of the case is metal. At the bottom of the silicone lining from sliding. The sound hitting the surface of the table is reflected and sounds great.
