In my opinion speaker burn-in is A BIT overrated -- a good speaker should sound pretty good new out of the box, so I prefer to just play them when I play them and let nature take its course. Sure it takes a little longer to burn them in this way, but you get the added enjoyment of getting to hear them evolve from decent sounding to fine sounding. Just my opinion as I say. Enjoy! I had RB-5IIs a while back and found them quite satisfying.
