They will both have the same sonic signiture it is just that the 2500 will have more bottom end and even at low volume levels will control the SF's better. The higher current driving capacity of the 2500 will give more substance to the music at all frequencies. It is not the 90 db sensitivity that creates the issue for the 2250 it is the 4 ohm nominal impedence.
