I just received the SA stands. A "hardware pack" for each speaker comes with two allen wrenches and two small black bolts which, I presume, bolt into the two screw holes on the front bottom of the speakers. Another "hardware pack" comes with the jam nuts, washers, spikes, and four larger black bolts. I don’t know where these larger black bolts screw in. Any ideas? I have sent an email to Sound Anchors on this, but thought maybe someone might have a quick answer. Thanks.
