First, I'm not saying he has to build a theatre room lol. It could be as simple as a throw rug, putting a bookshelf behind his speakers in his room, etc. Removing echoes and reflections from a room simply is a higher order difference than the price of your speakers. I don't care how good your speakers are, they sound terrible with echoes. Like in my room now... Do as I say not as I do.
Second, OLD speakers are not necessarily bad, unless they're broken or something. Finding an old pair of monitors/bookshelves and then hooking them up to a receiver or something with speaker connectors is always an option, and at least in the US it's usually pretty darn cheap if you dive dumpsters/estate sales/swap site listings. Obviously, this isn't a how cheap is cheap enough thread, dude literally wants to spend govt money. So spend away. I don't know exactly how cheap/old OPs current speakers are, but I'm not gonna knock them until I've listen to them in action, but saying his old speakers are BAD because they're OLD really tears at my trash picking heart...
