Happy addition after some tweaks
I'm so glad I worked through the various issues I had integrating this into my system. It works very well and adds to the experience in my 5.1.4 setup. Everyone i demo this for loves it. I find myself smiling when I watch movies. Last night I watched Ford vrs Ferrari and that inspired me to leave this review.
Some things to consider... The amp is set at 100hz which is way too high for movies. I ended up buying a 50hz FMOD RCA crossover and that smoothed things out.
The couch kit didn't work for me. This thing hits so hard it was lifting my LoveSac couch which resulted in some intense (almost scary) flapping on the floor. I would have returned it for this reason. Instead, I drilled some holes and mounted it directly to the couch base. Problem solved!
