Hi, I'm Jordi from Catalunya (North Spain). I have a question about IQ. Is this protocol an open and free to use system? Can I control my own Sub-Wooffer with build in DSP with the IQ protocol and the software that exists? I have acces to the DSP and I can program it. I want to make an interface for translate the information about DELAY, EQ and Volume than travels in the IQ protocol and insert it in the DSP of my own Sub-Woffer system! Thanks.
