According to Samson they're not studio monitors:
they're PA foldback wedges. There's no reason why they couldn't be used as general purpose PA type speakers, but I don't imagine they will deliver a very refined sound. They should however be loud.
You will need an amplifier to drive them. They're rated 175 Watt, with 8 Ohm impedance. Any modern amplifier will be suitable for home use, as 8 Ohm has been standard load impedance for decades, and efficient speakers like that will fill a room with any power from a few tens of watts.
It would just be a matter of having the appropriate leads - quarter inch jacks from the speakers to whatever speaker output is on the amp (typically bare wires), and 1/8 (3.5mm) stereo to RCA pair is usually what you'd need for computer to amp line in. If you found a straight power amp, it could also have 1/4" inputs, but the output from the computer may not have enough signal level to directly drive a power amp well.
