So as you say your circuit does not have the R2 resistor.
If you use one 10W R, as was said, or you think you need more power for some reason, say another application and you only have that wattage available, use 4 Resistors in series-parallel. Many manufacturers have 40W in their stock, but price goes up very fast, let's name only two (I am in Europe) MUNDORF and VITROHM. The other way (if you are afraid) of protection, is the use of a light bulb or a PTC in the xover (this may not be fast enough with the first being more common).
