LARGE speaker shipping options???

I'm downsizing to a condo and need to sell my HT and stereo speakers which I plan on listing here (Audiogon). However I'm not sure about shipping. I have original boxes but have several large and over 200lbs each and 100lbs each speakers. I'm guessing these would have to go by a freight line. What is the SAP individuals are using and doing for this?

Just want to have all my ship(ping) in order before I list.
