Call them up and see what they are offering. The training was really good a decade ago - I took both and got something from both.

There are also other training avenues as well.
Gold-line use to have courses to take.
The ASA (Acoustical Society of America) has courses.
JBL has courses thru out the year, as do other manufactures and test equipment vendors.
It is best to start with courses geared toward "small room acoustics" however. Since that is what we deal with. And the THX & HAA courses do that perfectly. The other courses come in handy as well thou - outdoor sound systems, large venues you might work on, and an expanded acoustic knowledge in general.
