Using JL Audio Esub with Merlin VSM

Looking to add a sub or two to Merlin/fila/Oppo 105 combo. Does anyone have experience using different input choices on sub....if so....what were pros/cons.
-high level speaker inputs with BAM in path
-high level speaker input without BAM
-line level using sub x over
-sub out from source/pre....in my case sub out from Oppo 2.1 application

 My room is somewhat small....maybe 15 x 12 x 9h

Surely someone has some valuable experience with JL?....

in your set up, what is your source to sub? Are you forced to use the sub as second volume control? JL does recommend using line level vs high level input. That would allow to use either Oppo or JL's crossover....using Oppo crossover would eliminate BAM...and probably still force me to use two volume controls.
SO....I would favor high level input so I could control all volume from Amp.

I recently hooked up 1 E10 using Oppo sub out & crossover. 
I used test cd and instructions from Barry O. As suggested in this thread.
-crawl around method 
-set distance on sub speaker placement to sure up timing
-dialed in phase deg. By inverting main speaker to reach NULL
on constant frequency.
 VERY  different from sound of high level speaker input method. I tried speaker input just as a starting point. Much louder But somewhat muddy.
My only issue is that I don’t notice much if any difference in crossover setting of Oppo. Not sure if that is normal?
just thought I would give an update on JL sub and my experience hooking it up. 
I don’t have ic,s long enough to try using JL crossover but I would think there may be a timing issue going that route.
