IMO, near-field monitors sound best carefully aimed at your noggin from fairly close range . . . and thus have a fairly small sweet spot. A pair of comparably priced bookshelf speakers will probably be more to your class' liking. For your purposes, a used receiver and some bookshelf speakers might be better; but I don't think the monitors are going to sound terrible relative to many of the other alternatives.
That said, I know someone that sort of haphazardly placed a pair of monitors in their garage's rafters and is happy enough with the sound. I wasn't so impressed, but politely kept my thoughts to myself . . . and the effect is kind of interesting. The speakers are sort of placed back-to-back and firing to the front and back of the garage.
