Packing & Shipping Large/Heavy Speakers

"simply crating" isn't so simple.  Still have to be protected and fastened right.  make sure to use softeners on the corners where you fasten it down unless you use clear wrap.

You might want to see if you have a local Craters and Freighters

They helped me with a pair of heavy and expensive ProAc speakers from NC to OR and they arrived perfect. The buyer was beyond pleased with the care they took to pack, crate, and palletize for a safe transit.

I agree  you need to hire a professional Craters and Freighters, They have a branch in Tulsa. They also may be able to make a recommendation on a company in OKC.

Learned this the hard way shipping carbon Kevlar fuel tanks to SOCAL many years ago. Not heavy but a bit more fragile that steel.

Definitely use a freight company, not UPS or Fedex.

Currently in the process of filing a claim for damages from using UPS to ship a pair of speakers from Texas to Arizona. Both speakers were damaged.

Never again!

Those speakers are huge.  Good suggestions here to use professional Craters and Freighters. 

Another option would be to draw a circle on a map corresponding to the miles away you are willing to travel to hand deliver them.  Double that circle and you would have the distance that you could meet a buyer half-way.  I am currently looking for a very heavy subwoofer and there are several that have been for sale for the past 3-6 months, but the sellers simply will not ship them and the distances to me are in the range of 12-30 hours by car, which is too far.  Based on this thread, I am going to get a quote from Craters and Freighters and, if I am ok with the amount, then I will reconnect the sellers to see if we can work it out.
