Shipping floor standing speakers


I have a brand new pair of PSB Imagine T2 speakers I'm going to sell. Can anyone tell me how I should ship them properly? They have never been opened and in original packaging.

Thank you

+1 for riaa....
If you're in a position to be able to put a second box on the original packing, it would be a winner.

I used to box up speakers from the loudspeaker manufacturer I worked for, and ship around the globe. Stand mount speakers in cardboard with foam had a soft material wrapped over speakers to not scratch the finish.
His larger 165lb floor standers went into ply crates, on a baby pallet.

It was an expensive learning experience, I often wondered if a GoPro attached might show them being dropped, rolled, or heavy items dropped onto them in transit?!
Thank you. Chris the back story is I traveled to an audio store several hours away. I bought an integrated amp, turntable and these speakers.

Before I even opened the box I changed my mind and decided to upgrade significantly...on all components. Thus my situation!
  How far is the shipping location?
meet halfway.?  
   We went through 4-5 pairs of Energy rc-70’s shipped, ups and fedex were used, 
bases wrecked, sides cracked, puncture holes in boxes.
took. Me about 5-6 months receiving, and sending back to get a good pair. 
  It’s a shame, all those great speakers destroyed in transit.
ups and fed ex guys are all morons, they don’t care, dropping the boxes off the truck to the street, 
    I’m sure the boxes was adequate, but the delivery guys were mindless, idiots!

good luck w shipping.
I would triple box w padding, more padding on a pallet for safety.
