In my case this great, -20 are 75 dBs of gain and indicates my Onkyo TX-NR809. If I put it to the fullest, would stay very high volume and can even use all his power dynamics, Audyssey in its sweep, would indicate that the subwoofer is very high gain and would have to adjust the volume in a few less dBs = gain.
Another problem is that if you leave the highest Subwoofer in a calibration, can affect the response time of the automatic power subwoofer, making it take longer to ignite.
Anyway, calibrated to 75 dBs as the reference indicates, this perfect and I notice the "Slam" and proper earthquake effect (present but without overwhelming the entire soundstage). lol
