The big sister of the 130 offers a 165 mm bass-midrange driver. With an extended bass foundation down to 30 Hz and an upper cut-off frequency of also 36,500 Hz, it also ensures full music enjoyment, whether as a monitor directly at the workstation or in hi-fi configuration on the shelf or sideboard. The efficiency here is even 92 dB and the maximum power handling is 220 watts, so even more dynamics are assured. The weight, however, gives an idea of how much technology is in the Symbol X 160.
