Local pickup for speakers - should I let the buyer in the house or use the the garage?

 NO FEEDBACK on USAM,how about eBay or other places where they have bought or sold?
Absolutely no feedback then I urge caution & stick to the garage,along with other security measures..
 I sell some things on FB & when I have anyone coming to my home I ask them straight out if they are thinking about robbing me & let them know up front they will be on video from the time they reach my front door..I don’t mention the fact that I will also be armed..

@freediver 

do you actually ask them if they're thinking of robbing you? That's crazy! If you asked me that, I'd think that you might be considering robbing me, and I'd run.

I would demo the speakers in the garage using my oldest cheapest amp and sources, just good enough to show that the speakers work.  I don't need to make them sound good, especially given garage acoustics and the mediocre upstream equipment -- not sounding great would be understandable.  Presumably, the buyer has already decided he wants these, so I'm not trying to give a sales demo here, just show that they're not broken.

I’ve always let folks in and been invited in to verify the equipment is working before a deal. If you feel uneasy have a friend over too.
