I see. Where does this leave us then? I'm using convolver [EDIT: I'm using Jrivers convolution-engine] with REW-generated freq-correction filters. What steps should I make to get proper LFE-sound level (as well as subwoofer-level for redirected sound?
Thank you very much for your help (and patience with my lack of understanding!)
Best regads,

My comments here are based on the assumption the your convolver filters establish a system with equal gain on all channels including LFE. I'll assume REW does that.
Here is a solution from Audiolense that Trumpetguy used:
In DSP Studio in JRiver:
*Move the "Room Correction" module to the top.
*Enable
*Amplify sub with 10dB.
This will attenuate the all other input format channels except the LFE with 10dB, while the LFE will remain at 0dB. This means those of you who have dedicated subwoofers with 10dB extra gain are wasting 10dB of gain. For those of you who feeds the LFE to mains speakers this is a perfect solution, where you have as much gain as you can have without risking audible clipping.
Here is another work around I suggested:
Put a -10 dB pad in the LFE channel interconnect before the power amps. EQ your room normally. Take out the pad for normal program playback.
Any rerouted bass now needs to be attenuated 10dB. JRiver does this automatically except with bass rerouted in user designed convolver filters.
Bass rerouting filters in convolver can be edited in the config file (.316 scale factor).
