It all depends on your room size (l x w x h), openings to adjacent rooms and their size, relative volume of the other speakers in your system.
My sub output level on the 1800 is set anywhere from -2dB to +2dB, depending on which memory setting I 'm using (which depends on what material I'm listening to, and listening position).
EDIT: for some subwoofers, using a y-cable to connect the LFE cable to both L/R increases the signal coming into the Sub, thus increasing the sub's output. again, that's for SOME subwoofers. not sure about your specific brand.
A couple of things to check:
Set your 1800's DRC to "Off"
Set your 1800's LFE to "0dB" (no attenuation)
Set Dynamic Range to "Max"
If still not enough, you can decrease the volume levels of your other speakers to compensate for the low signal coming from the sub.
Are you using a SPL meter? If so, using the 1800's pink tone, set the subwoofer volume so that it's 3-5 dB louder than your other speakers from the listening position.
Hope that helps.
