Hello everyone! Guys, can you tell me if it is possible to parallel resistors with different resistance in the speaker crossover? It is necessary to replace the 3.6 Ohm/10 Watt resistor. I don't have one, but I have two resistors for 12 and 5.1 ohms/5 Watt. Will there be any negative consequences from two different resistances?
If the power is shared reasonably between them. Space them apart some.
Using equal resistances does ensure equal power dissipation.

Yes, max wattage dissipated on 5.1 ohm resistor will be 7W - that is too much for a 5W resistor, it may overheat and broke. Correct wattage for 5.1-ohm resistor is 7W at least.
If those resistors are all that he has, certainly they will work. The original rating should have been conservative,
and would only matter at loud volumes anyway. Probably it's a tweeter attenuation resistor.

Yes, it is. In our backwater, I found a 3.6 ohm resistor, but at 5 watts. Works. It doesn't warm up at the volume I'm listening to, but there's always someone who wants to turn the volume up a bit more🙂.
