Thanks for the input again everyone. Spent way too much time looking over all the options. I was most tempted by the rythmik f12g or l12 but didn't want to have to worry about shelling out for return shipping if I found I didn't like it or a sub. The svs sb1000 was also appealing, big driver in a small cabinet, and free shipping both ways within the demo period. Ultimately it came down to finding a 3mo old rel t7i locally for almost the same as a t5i so I did that. Setup was painless even doing it alone. Everyone says that they wished they tried a sub sooner, but guess I'm not. How else would I have known exactly what I was missing. Forget the bass and low end, it's all about soundstage for me. Almost makes my setup seem shouty and super narrow without, which matches what most everyone else says. So far the rel is plenty punchy and able to keep up with single driver omegas based on a couple days off listening. I'll leave it there since I have nothing else to add. Wish I had a bigger listening area to consider a second sub but this will have to be it for now.
