Is my room big enough for ProAc D38's

Room Size 14.5 ft wide x 19.5 ft long x 8.5 ft tall. Dedicated media room. I currently have ProAc D15's and am looking for more of a true full range experience. I've heard a lot of good things about the D38's. I run Theta gear for electronics. Will the D38's complement the room size well???

Other speakers I plan on auditioning are:
Avalon Ascendant
Wilson Sophia II
