Audio EAX 5.0?

I'm making a game with some assets I found off the web. The maps and such are there, but I need to add 3D sound effects. FMOD is not the best at this. Could I use OpenAL EAX libraries for more realistic sound quality?
Here is a video demoing what it can do in Software via OpenAL (demo of hardware EAX5, is usable with OpenAL on modern systems and on onboard audio)
