How do wireless subwoofers do this?

I love the idea of adding one or more subs like the Syzygy ones   to my system but I'm confused as how it would work. 

As I understand it you hook a wireless transmitter via RCA cables connected to your preamp outs. Then the signal is transmitted wirelessly to your sub, some of which even have DSP room correction. All good so far.

Here's what I don't get.

Say your speakers go done to 35hz, and typically the subs suggest setting the crossover around 120 or 80hz.

Doesn't this mean there is an overlap of what the subwoofers are covering and what your speakers are covering so both your speakers and sub are producing any music below 120 or 100? Doesn't this cause distortion?

Or does the DSP function solve this, so the sub is only functioning below your speakers?

Both my subs are wireless but I have never bothered to try them wired so cannot compare.

However I went wireless for a different reason to most I am sure.
With my old wired sub I was getting some ground loop hum I could not eliminate.
The first wireless sub cured that and even though I have changed main equipment since which may have also fixed the ground loop hum I have never bothered to try wired again.

Besides as noted it does make placement and cable runs much less of a problem!
