If the B&W has speaker level binding posts you can connect the sub just like a pair of speakers to the Amp.
Connecting a subwoofer
Hi everyone, I’m wondering whether I can connect my subwoofer directly to my amp. My VTL preamp is temporarily out of service, so I’m listening to music the following way.
Wiim pro streamer>Auralic Aries DAC>MC275>Sonus Faner Olympica I.
In the current setup my B&W sub is out of the picture, can I plug the sub into the amp, if so, how?
Thanks
