Well, my 4BSST took forever, but that was the dealer's (West L.A. Music in L.A.) screw up...the BP6 purchased from another dealer (Reference Audio/Video in Gardena, CA) came rather quickly.
I'll never do business with West L.A. again. They are not professional. At least this guy I dealt with wasn't.
I highly recommend Reference Audio/Video. The owner, Ken rocks!
