This way , everybody using closed box main loudspeakers can make them go 20 Hz deeper in the bass .
If doing DIY and making a closed loudspeaker, one can make the boxes half the size and get the same deep bass with a Linkwitz transformer filter ( the cons are some limits in SPL ) .
This is easíly done with the use of PEQ in the Ultra.
Where the bass starts to drop off, at , maybe - 6 dB at 50 Hz you set the shelving filter in the PEQ to do the opposite , + 6 dB with Q =1 at 50 Hz . This way you might have a flat response inroom to 30 Hz or lower. Laborate with gain, frequency and Q values, after some hours listening you will have a much better bass sound than before.
If needed, If there is a little elevated frequency response just above the bass rolloff, one can use higher Q values for the shelving , such as Q=1.21 to equalize this - like in this Linkwitz picture.
