Well, I managed to talk some into letting me demo their newly constructed Orions. After months of back and forth e-mailing, the guy says I can come over this weekend.
However, I've never done a speaker demo before. What's considered proper etiquette? Should I bring something over (besides music) as a gift? What's a normal amount of time to spend listening to them?
I don't really know this guy save for a few e-mails, but I know he's local and he's reputable (college professor).
Any tips would be welcome.
