Well, I finished my quad EHQS12 build just last night and I figured I'd share it with all of you here. What I ended up with was 2 dual boxes that are (WXDXH) 16x19.5x50.5. It ended up costing just a little less than 150 for all the parts going into the subs(350 if you count the amp thats coming and feedback destroyer). I don't really know what else to say except for that it was a fun trial and they turned out sounding awesome. I feel bad saying this, but at levels not extremely loud, I think I prefer the sound slightly to my 16Ov.2s. Granted the 16Ov.2s go much much louder and lower, making the EHQS12s not at all competitive in that aspect. I did get surprised though at how good they sound.
BTW you'll see a few pictures of my 16Ov.2s in there for comparison.
