I see in class D amps datasheets some advertising about the PBTL config providing 1 channel with twice the power. However, this only seems effective with low impedance drivers (2-3R).
Looking at datasheets, I don't see 5", 6", 8" drivers with "low impedance": 4-8R seems the norm. Is this correct? In those cases, the PBTL does not looks much relevant.
There seems to be better use cases for subwoofers, by combining dual coils for ex. So PBTL configuration would be relevant only (almost) for subwoofer?
Can PBTL help for woofers ?
Best regards,
