At the top in the graph you can see the effects of the crossover. As you can see here, this channel is crossed over at Hz with a slope of 48dB very steep slope. Here are some round numbers to help you get started if you have never set crossover points before. This means that you can not only boost or cut any one of 31 frequency bands, but you can also choose the center frequency of each band as well as choose the "Q" value of that band more about that below.
Below you can see a comparison of the same EQ adjustment with two very different "Q" settings. Both screenshots show the same 18db cut at 1khz but with two different "Q" values. On the left the "Q" is set low. When using a low "Q" value many of the surrounding frequencies are affected. On the right the same adjustment is made but using a very high narrow "Q" factor.
With a high "Q" value there is very little affect on surrounding frequencies. The center frequency of that EQ band is pretty much the only frequency range that is affected. For low frequency adjustments to woofers you will typically use a higher "Q" value. The default "Q" value of 4. At higher frequencies tweeter range a lower "Q" value is recommended. Sharp changes in frequency response at mid and high frequencies do not sound good. The way that humans process and perceive sound dictates that we are much less sensitive to dramatic changes in bass frequencies than we are to dramatic changes in higher frequencies.
Use a second smartphone and download any one of a thousand free RTA apps. Also download a pink noise track. It shows the frequency response of your sound system using your smartphone's built in mic. Pink noise is a special sound track that sounds like FM static. It is a recording of random bursts 31 bands of frequencies all at equal levels. If your sound system was perfect none are all of the bars on the RTA would be level with each other and form a straight line across the screen.
In the real world that never happens. Using the RTA app you will be able to see what frequencies need to be cut or boosted. This will help you identify problem areas and quickly make the correct adjustments using the DSR1 EQ.
Make sure that you have the correct speakers selected when you make EQ or crossover adjustments. This is easy to miss.

Higher order slopes of 24 to 48db will allow you to play your speakers louder and harder without damage but may not have the sound you like.
Subwoofers should always be bandpassed. This means that you use a combination of high pass as well as low pass to form a narrow bandwidth that the speaker is allowed to play within. A good starting point is a high pass of 30 to 40hz and a fairly steep slope of 24db or higher. This will effectively filter out a lot of wasted energy that will only over work your subwoofers and tax your charging system without producing any more sound that can be heard.
Combine your high pass with a low pass that will reduce higher frequency information from being sent to the subwoofers.
