The big sister of the 130 model features a 165 mm mid-bass driver. With an extended bass foundation down to 30 Hz and an upper cutoff frequency of 36,500 Hz, it ensures full music enjoyment, whether used as a monitor directly at the workplace or in a HiFi configuration on a shelf or sideboard. The efficiency is even at 92 dB, and the maximum load capacity is 220 watts, ensuring even more dynamics. The weight, however, hints at how much technology is packed into the Symbol X 160.
