I've used Uship.com in the past. It allows you to create a quote for what you'd like shipped, lets you pick the level of service you want (up to and including white-glove treatment) and then lets shippers bid on it, including letting you read reviews before selecting one.
Shipping heavy speakers
I have had a few offers on a pair of Revel Salon1's that i've shied away from because they weigh 240 lbs each and the offers all came from 800 miles away or more. Can you guys offer me some suggestions on how to ship these speakers? They're in near showroom condition and it would be a waste to see them destroyed. Tks
