Use a Combo amp (2 x 12") as a Speaker Cabinet - 2 solutions but with a question

[kagliostro]

I've find two possibol solution to the question





Both solutions plan to equip the combo amplifier with a female jack socket and use a cable to connect the combo amplifier to its speakers or connect the speakers to another amplifier

Does anyone know if it is possible to exclude the use of a cable to connect the combo amplifier and connect it directly, without the cable (only the original speakers wires) and to exclude it by inserting a cable that connects the speakers to an external amplifier without losing the possible options offered by the two schemes that i posted , or, at least, maintain some option ?

Thanks
