I just moved and have 4 CSS Trio 12s. I'm starting fresh since I just moved. I'm not sure what I want to do with these yet. They seem better suited for 19hz ported design than anything, but I'm thinking a pair of dual opposed.
Space is somewhat a concern, but not the end all. I'm more interested in sound quality (aka flat response) than anything. So spread out multiples would be good. The extention of a sealed design is appealing, but not the end all either.
What should I do? I'll build a couple test boxes and am prepared to rebuild if it doesn't work. And I can test outdoors and indoors. But would like to at least start in a reasonable direction.
