I've been really busy recently and distracted from this project, but thought that I should provide an update. If you're familiar with the term "askhole" I'm trying to avoide it applying to me.
I did call the local professional and got a quote ($400) for coming out and doing a full setup. He also recommended that we consider a Symetrix Jupiter 4 ($1,000) for our application. We had a long discussion about how the monitors, under balcony speakers, and main speakers all needed to have a different EQ to achieve the best results.
At this point I'm working with the rest of the AV Team to evaluate our options. I know that the Church Board would approve the $1,400 (because they trust us) so it's important that the AV Team have consensus on the best solution. My personal feeling is that I would prefer to have something with more flexibility than the Dx38 if we are going to spend the money to have a professional setup done. I think I may have to contact the person that previously helped setup the system in my church originally to see if he still has the equipment and willingness to help. I am not sure what his level of skill really is, but it shouldn't cost anything to find out.
I'll take another look at the Sabine GraphiQ.
Thanks again for the ideas and information.
