While you didn't ask for a response, I think a decision might be considered as to whether this is a forum about buying manufacturer built speakers or about DIYing your own line array speaker systems.Most of the discussion over time has been about building them oneself. Only recently has the discussion turned to buying someone's already manufactured or pe-manufactured kit.
Its a valid discussion either way, but each choice will have a different set of interested posters.
If you are the moderator then you should encourage the participation in either individuals who have already built their own systems from scratch, or manufacturers who are trying to sell their wares to the speaker BUYING rather than speaker BUILDING public.
The devolving of the forum has happened around these two topic possibilities.
