I've seen a couple people mention putting a small baffle between 2 speakers to separate them from canceling each other out. I'm just wondering if this is a good practice or not on a spl only box

Testing would be tough because it would change the volume of the box, and I'm not sure if I should add it to my box as I'm tunning it.

Here's a crappy pic to give you a idea of what I'm talking about.

 

Btw, thats the port on the left of the diagram. Not another baffle.

 

Pointless to me i would suggest putting a brace in between the subs, but if they are both running of the same amp it is pointless, if they are on seperate amps both should be seperately enclosed.

 

that does gain, same amp or not. i do that in every single common chamber box i make.

 

I am with Yuli, I would use it as a brace as well

 

Thanks for the replies. Looks like I am bracing it.
