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?

Subwoofer DSP room correction does not implement a crossover. A preamp with bass management will implement a crossover.


A crossover is a combination of 2 filters.  Low pass and high pass.

A subwoofer's input can certainly implement the low pass. The high pass function is the main speaker's natural roll off.

So, it is possible to implement this limited filtering in the subwoofer alone.

Ideally, the sub handles the integration seamlessly.


Yes, you can do this without adding a filter on the satellites. I do it this way. I suggest if your main speakers are ported, seal them before calibrating.

Best,
