How do I get the Core macro "X-over 3wLR4+" to output sound?

Hi,

I am dabbling in multiband processing and ran across a Core macro in the factory library titled "X-over 3wLR4", which seems like an ideal way to split a signal into three discreet bands via Linkwitz-Riley LR4 filters. And got stuck trying to get it to work as intended..

The Reaktor Core manual advises to use a "X-over 3wLR4" to split the signals, sending each band to be processed, and then recombining the splits with a "X-over 3wLR4+" macro. Doing it this way apparently solves all that nasty phase/sample delay issues which might otherwise manifest from multiband processing. However, when I connect the split band signals back to "X-over 3wLR4+", all audio output is muted..

What am I missing? Any further insight would be appreciated. Attached screenshot shows what sort of core patch results in no sound.. If patch the "X-over 3wLR4" directy to the outs, I do get sound from the splitbands as expected..

EDIT: There is something I am indeed not getting.. "X-over 3wLR4+" looks like this inside - that red can't be good right?

EDIT II: Ok, so supplied the SR bus bundle from the splitter module to the combiner, and now I do get sound.. So I might have solved it for now, but appreciate someone explaining to me why this particular macro wants the SR bundle when many others work without it?

It's not just an SR bundle

Bundles can be any bunch of connections. In this case it contains two different parameters one from each of the internal filters in the main crossover filter macro, they are 'prewarped' filter cutoff values. Looks like the '+' macro needs one of those to make phase corrections prior to mixing.
