OK guys, what would you do?
I've been messing with sub placement for what seem like forever. See this thread
if you want to know the details.
Anyways, I've basically narrowed it down to 2 different configurations:
- 2 up front / 2 in back
- all 4 up front / 2 stacks of 2
This is with 4 XS15s (original, non-SE).
Here's the measurements:
Here's the waterfall comparison:
Green is front/back, red is stacked up front. As you can see, I'm getting much better extension with all 4 up front (+20db at 10hz!), but I have a huge suck-out from 55-67hz. I prefer the sound with all 4 up front, but seat-to-seat variance suffers...heck, if I just lean forward in my chair the response changes significantly. That being said, I rarely move around when watching a movie or doing critical music listening...and my wife couldn't care less.
It could just be in my head, but I swear I miss that narrow band where the null is....it is pretty narrow though...prolly in my head.
Oh, and when I have all 4 up front, I only have to run the subs 4db hot. When they are in the rear I bump them up 7db.
I want to get a couple more subs to put in the back of the room fill in that null and smooth across seats, but until funds become available....which set up would you want to live with?? Do you think upgrading all 4 to SE would be worthwhile or no?
