What do you mean by overload? If it is a power handling limitation in the amp, get bigger one. If it is a power handling limitation in the speakers, get the 800Diamonds.;-)
If it is an acoustical problem, as suggested, you need to (in order of preference) either (1) reposition speakers and/or listener, (2) treat your room with bass traps or (3) consider EQ.
