Yamaha's NS-AW392 speakers are mounted on the wall using a special stand. Their power is 40W RMS, which means that they can be connected to an amplifier of the same power. But you should also check the impedance of the speakers and amplifier to make sure they are compatible with each other. These are 2-way speakers, that is, the sound frequencies are reproduced by two loudspeakers, a tweeter for the highs and a woofer for the lows.

Frequency Response: 60 - 25000Hz

Sensitivity: 86dB
