The picture shows bars in question. I was going to upgrade the insulation in Jbl 4343. I removed this bar in order to install new insulation. Any idea what the purpose of it is? I know the bolts in the back of cabinet used to have a tag saying something about their purpose, but can't remember what it said.

It's probably there to reinforce the cabinet for wall or ceiling mounting.

Yep, that's their purpose.

I can make a photo of the tag tomorrow (hope the text is still visible).

Ok. So for floor standing, they are not used. I thought they were for cabinet stability but I did not know it was for only wall mounting. Thank you for the information

I would suggest you reinstall it so that any future owner doesn't lose most of the cabinet and all of the drivers down on the customer's heads (or friends or family).
