Hello, friends! I wanted to use the TDA2050 amp to power a system of two drivers, each 4 ohms. 6.5 W should go to the tweeter, 15 W to the woofer. Crossover and Lpad diagram in the figure. R1 = 1.3 Ohm, R2 = 7.6 Ohm. But I'm not sure about the overall circuit resistance. After all, the drivers are connected in parallel, so their total resistance is about 2 ohms. But this is too little for the TDA2050! Or am I wrong?
Please, help me to understand.
PS. Unfortunately, I don't have 8-ohm speakers.

The total impedance will be about 4 ohms, not 2. The cross over steers the current to the woofer at low frequencies and to the tweeter at high frequencies, and at the cross over point the network ensures each presents about 8 ohms, so their parallel combination there is still about 4 ohms.
Assuming the values are correct!
