Good Sounding Speaker that Won't Attract Thieves?


Moving my painting & drawing studio (formerly our living room + den while the wife was at work) to a 14' x 24' metal barn and am basically looking for a pair of speakers with a sonic personality generally similar to a JBL Century 100 that I can pick up cheap at a rummage sale and run with a plain Jane 2 channel receiver. Preferably something that's a sleeper, soundwise, but which which, cosmetically, practically screams to a crack addict, "You probably couldn't even trade me for a six pack of beer." Any suggestions?

Aside from us, nobody buys anything that won't fit in their pocket these days.
Big, heavy speakers would be the answer if you're really worried about it.
If no one knows you have it, you should be good2go. An alarm system should be used.
I can only suggest what not to buy - Sonus Faber Minima Amators. I had some stolen in a break in. They look great and are easy to carry. They left the stands!
