The big sister of the X 130 is equipped with a 165 mm bass-midrange driver. With an extended bass range that delves down to 30 Hz and an upper cut-off frequency of 36,500 Hz, it ensures full music enjoyment regardless of whether it´s used as a monitor speaker directly on a workstation, or as a speaker in a hi-fi configuration on a shelf or sideboard. An efficiency level of 92 dB and a maximum load capacity of 220 watts ensure a high dynamic range. The dimensions, however, remain pleasantly compact: Measuring 186 mm wide and 310 mm high, it is hardly any bigger than an A4 sheet. A weight of 3.3 kg, however, gives you an idea of just how much technology is incorporated in the Symbol X 160.
