Do Studio Monitor Speakers Usually Have RCA inputs On The Left, The Right Or Both

I found some fairly priced speakers by Technical Pro (MB5000). They claim to have RCA inputs, but I dont know if I need just one L/R or 2 L/R (both speakers) to connect directly to my sound card.

It seems that one box contains amplifier and PSU, with speaker wire going to the other box. You need just single audio out.
