Question about Sony Str-Dh190

There is no subwoofer output. I cannot make a speaker recommendation, as this depends on personal and spatial factors. However, it is important for the connection to the STR-DH190 that the speakers have a nominal impedance of 6 ohms or higher (Sony requirement for this receiver).

This reciver has no subwoofer output. 60 - 80 watt speakers are suitable. There are many brands and price ranges, you have to choose for yourself.
