Recieved an email from the Homeless Man. His loudspeakers are still available, no they haven't been test in a lab, and he will not reveal his source for speakers. Nevertheless, I did find on the Internet were his is soliciting for someone in China to supply him with speakers.
Its survival in the city
When you live from day to day
City streets don't have much pity
When you're down, that's where you'll stay
Just me, The Man, keeping Homeless Man down.
