Help shipping a speaker over seas

It might be worth your effort to actually crate them up inside of a wooden crate. Anything to make them more difficult to damage. Tvad is correct that speakers are very prone to damage. And, if you can, airfreighting them, despite it being more expensive, will do even more to protect your speakers.

Good luck!

Yup the faster the shipping the better for speakers. Triple boxing?..you should be fine. FedEx express did a fine job with a pair of 240lb speakers I shipped over seas..they arrived without a scratch.

First of all, please kindly consider what country are you going to ship that speakers. I would assumed you are sending an expensive pair of speakers. So make sure the buyer will pay for import duty. Triple boxes? 40 lbs per box? It only helps a little unless you have protecting material between each box. Good luck

Here's a few more details as requested

I'm shipping these to Europe
I will be using styrofoam to protect the speakers for each box
The speakers MSRP is approx 4k

Use Bax Global. I shipped a pair of Wilson Duettes during the Winter to Hong Kong. They arrived without issue in 2 days and cost less than shipping via UPS ground to California (from Michigan). The shipment was one crate at over 100 pounds. This is exactly where BAX specializes and they do an excellent job, fast, reliable and reasonably priced. For what it is worth, we ship all of our (my company's) equipment for the optical disc industry to Mexico vis BAX Global and have never once had any damage or lost shipments.
