[OB] Please! my new old paradism 21 or 18 with a 0.7QTS

Hello all,

Please could you try to help me to replace my good old two Visaton WS25E (1:QTS and 0.8m^2 of emissive surface) with an ultimate 21 or 18 (0.7QTS) for a small room !

A good OB is 15" Dayton IB385-8. Never tried OB for the ultimate, is it good?
