A:Answer For wireless speakers, any of the models in Denon's Home Series speakers which have a very open, room-filling presentation. There are three models; small medium, and large. It just depends on the size of the room you have. There's also a Soundbar.
A Sub-woofer can also be added to any of these speakers.
The Home speakers do plug into the wall for power. And to work wirelessly, the Home speakers need to be partnered with a compatible device - like the Marantz Model 40n, or any of Marantz' receivers, which the CD60 can be connected to with RCA cables. The CD60 is not a wireless device itself, but it can be connected directly to Denon's Home speakers with an RCA to 3.5mm cable.
