That is gold right there! Looks like a pair of Abbeys and maybe a smaller Nathan center channel. They will work especially well in your smaller room since they're controlled directivity designs. You definitely need to use the subs as the Abbeys do roll off fairly high, despite the apparent size of them. Being pro drivers they are also rather efficient, so high power isn't as necessary. Start out with REW to measure and integrate them with the subs and you're mostly good to go.
