Wiim Ultra with REL T/x series subwoofers

[Promso]

Hi Guys!
I bought Wiim Ultra and pair of active speakers with integrated amps.
Think to order now REL T7X subwoofer, but I found in manual that they highly recommend to connect the sub as an inactive speaker for best quality. Screenshot from manual attached.

Anyone tried to connect such sub to Wiim Ultra? Which connection method you use? How is the quality?

I’m thinking that maybe it will not perform as well as it should if just connecting through sub out on Wiim and then maybe not even worth to overpay for this nicely sounding sub and just order something a bit cheaper.

I connected my ULTRA by splitter cable to both HT1205 Mk2 L/R IN. I did it instead of just using one cable to LFE IN on the Sub.

It slams harder, more punchy and requires less volume set on Sub. Now it seems to me that it's better

Why is this happening? Is it because there is simply 2x signal is going to it? Could this have any additional benefits from just simple one cable connection? Any risks? Additional noise or something?

Thanks for reminding me. Do I connect the sub and Wiim Ultra using the following cable?))
