Question for those who use REL subs with Wilson speakers


Question for those of you who have experience using REL subs with Wilson Audio speakers:

I have Wilson Sasha 1s with a pair of S/812s. Love the sound. Before getting the subs, I had considered possibly upgrading in the Wilson line eventually (I had Sophia’s before). However, now I am wondering if it may be more effective in terms of overall sonic improvement to perhaps add a second pair of S/812s or even eventually having 2 stacks of 3 with my Sashas. I am very happy with the sound I have now, so I do not feel like I have to change anything at all; but I am intrigued by this question. Thanks in advance for your opinions.

Sorry, can't offer any opinion, just a couple of comments.
Do you use corner bass traps? If not, you might get more effectiveness with them.
Have you tried stacking the 2 subs that you already have to get a sense of what it might sound like having them stacked? Try doing to both sides of the room.
Just curious how big your room is, and what amp your using. How are you connecting the subs (amp-speaker cables, xover, preamp).
