Magnepan 1.6 - packing?

You do not need that extra piece in order to pack your 1.6's. I shipped mine long distance without, and they were fine. It seems odd to not use it but the box will be more compact without. Good luck and insure!

Call them...they should be able to help you out!

I would be nervous as well. I don't remember how my Maggie 1.6's pack, but I would look to see that you have styofoam on the bottom, top and in-between the speakers. Those are the areas I would look for styrofoam and as I recall, the box needed some compression to seal properly. I hope this helps. :o)
