Large woofers and highpoweroutput mean the A5 provides an immersive listening experience even in large rooms, thanks to a generous 5.5 liters of acoustic volume.
To meet the need for low weight and highpoweroutput, the designers opted for the same lithium ion technology as used in the batteries of most modern smartphones and laptop computers, where the demands are rather similar, but on a much smaller scale.
The TX-NR807 has seven powerful 135-watts-per-channel Onkyo WRAT (Wide Range Amplifier Technology) amplifier sections for highoutput and low distortion, offering a dynamic power rating of 300 watts into 3 ohms.
