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?

Vintage KLH or AR speakers///Usually look beat up but still sound very respectable..I actually like the KLH 6 very much.........
why not just weigh the speaker down with lead and sand then bolt it to the floor. That should be much more then any thief would be able to handle?

I have a friend whose house was broken into on several occasions. The thieves would walk past the Wilson Watts, Audio Research and Theta to steal his Sony TV. Finally they broke in and stole the woofers out of his Duntech Sovereigns.

So, I guess the Wilson Watts are the way to go.
