You could use one of these on the reflector and 5" ducting from it to the fan.

I would put 6" "increasers" (reducers lol) on the fan so you have all 6" ducting exept the fan itself. You lose a lot of flow through ducting so keeping it as large as possible will be good.

Also the airflow in the ducting will be slower which might mean less noise.
