Rumble 100 question

I've tried to search but I always get lost on the technical jargon used on most music forums.

When using my rumble 100, if I use the line out XLR port, would the signal coming from that port be an equivalent to the one going to the rumble driver speaker, or would it be the "raw" signal from the bass built in electronics but just in a balanced connection?

Another question related to this: Is the XLR out good to plug into what? Can I plug it into a digital interface? What about one of those large speakers with XLR inputs?

I'm asking this because I've been playing a lot with the EQ and effects on the amp and I've found some quite nice tone for some settings, and it would suck to lose that if using the XLR out. Thanks for everyone that answers this.
