With SAM engaged, the speakers go as low as the sub, so extension was not my problem. It's the fact that from measurement, I know that I have a GIGANTIC wide + deep suck-out at 50Hz. By being in just the right place near the corner, the sub is able to fill that in, with a much smoother bass response graph.[quote pid='81336' dateline='1548074421']
So the success of a sub might depend more on the 'nulls' in your room. Also, getting the time-alignment right took weeks, and I found that the SAM% setting had a critical effect on the smoothness of the response (due to phase relationships), finally ending up with 25% as the best.
Don't forget that once you engage SAM, you can't use REL's High-Level connections from the speaker terminals.
How so? That means I need a preout version? I might just get a 140 Pro as other models seem to be overkill for LS50.

So be sure to get the optional pre-out board installed.
