HomePod has multi-room support thanks to AirPlay 2, but your five-year-old Bluetooth speaker can't join in on the party. That is unless you have Airfoil. It's a simple program that lets you stream audio from your Mac or PC to any AirPlay and Bluetooth speakers at the sae tine.
Though you can currently AirPlay to multiple devices from iTunes on your Mac, it's only possible with iTunes and doesn't combine AirPlay and Bluetooth speakers. Airfoil is incredibly universal, allowing you to use AirPlay and Bluetooth to stream music to as many devices as you want from any audio source you want on your Mac or PC.
See at Rogue Amoeba
Did you say it works with both AirPlay and Bluetooth?
