When i got the monitors (which are by no means great) it was unbelievable how shit these sounded.
i was using:
this bullshit i bought from a guy for like 12€
the cable with volume control on it was fucked and they would only play properly when the volume control was set to max and the cable was in a specific position the sub wad fun tho, even if it was all mud and it wouldn't play below 50hz lol
before that i also used these badbwoys
to which i 'expertly' wired (gonna post a pic later) speakers from old Aiwa stereo - something like this - sub was acting like an amp
