I see. So in effect you have the speakers and the sub wired in parallel to the WiiM Pro outputs.
Sadly there's no way to adjust relative delay between the speakers and the sub in this kind of setup. But that may not be such a big deal if you are still able to get a smooth frequency response after RoomFit.
By the way, which SVS subwoofer do you have? If it the older fully analogue model (e.g. SB-1000 Classic) or one of the newer models that is DSP-equipped and comes with the companion app?

If it sounds good, it is good.Yes, I have connected them in parallel. Moving the Subwoofer affects its delay. SB-2000, not pro version. They sound good. Later I can post measurements of the frequency response.
Enjoy!

To be honest, from raw performance perspective your existing SVS SB-2000 (12" driver, -3dB at 19Hz) should actually be a better sub than the Genelec 7050 (8.5" driver, -6dB at 24Hz).View attachment 34721No need for a separate subwoofer output from WiiM
Note that your SVS SB-2000 (non-Pro) also has a built-in high pass filter (12dB/oct at 80Hz) on the line outputs. The Genelec 7050 has a built-in high pass filter at 85Hz on the line outs.

I was thinking this same thing as well--integration is all well and good, but at the end of the day, the outright performance of the unit is what matters most with bass and, "real subs," are in a completely different league from that Genelec.

You can still use the phase control of the sub to tweak the integration.Yes, I have connected them in parallel. Moving the Subwoofer affects its delay. SB-2000, not pro version. They sound good. Later I can post measurements of the frequency response.
I'm happy with how well the SVS matched the 8030. Yeah, the 8030 has that crossover 85hz dip switch, and the SVS likes to be a 90hz crossover. The Wiim RoomFit corrects 20-160hz and does it well. 
I don't have a measurement microphone yet, just an iPhone. I really like the WiiM pro and it's much cheaper than some Genelec room measurement.

Some measurement. The subwoofer volume is about 3/10 in that measurement. Do I understand correctly if I still need to lower the subwoofer volume? The 8030 are the old A models, so they also have their own volume control.
I'll have to look into it a bit more later. Thanks for the help.

The subwoofer level is high relative to the speaker level, yes - though RoomFit is taking care of the level mismatch so you could just leave it as is.View attachment 34733

A benefit of this approach is that you get smooth extension down to 20Hz, at the cost of reduced max SPL.
Your response after RoomFit correction looks quite good to me, actually.
Thanks 
A reduction of 30 dB by RoomFit is a bit much, though. RoomFit will probably combine (or waste) multiple PEQ filters to realise this attenuation. The subwoofer level could probably be reduced by another 10 dB without having non-boost mode running out of steam. This could free up PEQ filters that might or might not be put to better use by RoomFit.
OTOH the response up to 200 Hz looks very good already.

I would like to return to this topic. Now that I have been listening for a while and have tried different settings, I can tell you that:
I think that my bass adjustment doesn't need to be very precise, because the measurement already shows that I have strong room reverberation at around 51hz-60hz.
Another point where I have a room echo problem is around 200hz. I understand very well that I would have to treat my listening space better with some bass traps and so on. (I don't live in a music studio).
However, measuring has helped me understand things like: My old Genelec 8030A speakers, (The Genelec 8030A was in production between years 2005 - 2013). They still work well, and there is no channel imbalance or anything.
WiiM measurements have given also me an idea of what kind of room reverberation problems I have. I have also managed to make the Genelec sound even better with the measurements, cuz I got those DIP switches to better positions to better respond to room echoes on Genelecs.
So I've achieved all this with this cheap WiiM pro streamer. I'm thinking next ahead; Pro is starting to sound boring, I have in mind the Fosi DAC, which has XLR connectors, and an option to rolling opamps. I can also fix the room echoes, little by little, and also get a better measurement microphone.
I think that, sun is shining to this purist from high.
And so on, and and thank you All. Cya. 
and, God bless,

If you are using its analog out then I wholeheartedly agree!
imo an external dac is a must for a pro. I have 3 pros with external dacs, and they are great!
I’m also using an external tube-based AD1865 DAC with the WiiM Pro, and the sound is to put it mildly at least two levels higher. So for me, an external DAC is a must. That said, the WiiM Pro is still worth its weight in gold for streaming and room correction. Cheers!I would like to return to this topic.

Honestly room treatment, positioning of subs, listening position, „roomfit callibration“ is 60% of the story, 30% is the listing material (how songs have been recorded) and 10% is the DAC - at least for me. For me the Pro DAC is already very very good. You might see it as „boring“, but psycho acoustics is another topic… 
I completely agree. Before I positioned the speakers and sub properly and then ran room correction, the sound wasn’t even close to good in fact, it was somewhat disappointing. But a good DAC still makes a difference. Whether it’s just a few percent or more, I’m not sure, but yeah.Honestly room treatment, positioning of subs, listening position, „roomfit callibration“ is 60% of the story, 30% is the listing material (how songs have been recorded) and 10% is the DAC - at least for me.

We could 
about this for hours!
The 3 worst dacs I have heard are wiim mini, wiim pro and fiio k11 (although I like the k11's headphone output; it's the rcas that suck).
But yes, my other dacs are otherwise somewhat similar and some judicious EQ etc. has far more impact.
For me, even high energy dance tracks are boring via a pro's analog output!

This might be also depending on the rest of the equipment…
