    The one in the second picture is a 5 watt, 1.75 ohm resistor.

    You should figure out why that resistor cooked before you replace it.

    I also noticed both lead ends on the board at D2 are green meaning the wire has oxidized. That issue needs to be addressed.

    Seeing oxidation on some of your driver leads, as mentioned above....
    Best bet, replace resistor with a 10 watt (or higher) of same value.
    Were the speakers played very loudly recently??

    Polk no longer has any parts for the LSi25 to my knowledge. You have been giving excellent advice above
