new stereo

so today i was doing yard work for my grandpa when his neighbor came over and asked me if i had my own stereo, and i dont. he told me he had one he was getting rid of it and, asked if i wanted it and i did. so as we are removing the stereo system he asks me if i want the huge ass speakers that go with it, these big speakers come up to my hip and im almost 6 foot. so now i that i have them set up in my room and tested them there so loud that im scared to turn them up to max. the actual system is about 10 years old but its in great shape and works just fine so far so its pretty awesome that i got it for free.
