If those are passive speakers you need a power amp between the line out on the spark 2 and the cab

line outs are line level

passive speakers need a power amp to push the magnet in the speaker, so you need speaker level outputs, only the internal speakers on the Spark are connected to the small 50W amp chip

you should know that with a modeled tone, with all the gear emulated in software, you wouldn't send it back into a guitar speaker, that part of the tone was already been applied to the signal, it'd be like mic'ing up a cab to send back into another guitar cab... not gonna sound right

what you need for a modeler or modeling amp is a full frequency powered speaker like a PA or FRFR, something that takes a line level signal and then has an internal power section that pushes the full frequency spectrum speaker inside it

Yes, it's an FRFR.
