So I know these speakers are overkill in one of the most righteous ways......but maybe a projector and AT screen are in order at some point to keep up? With an AT screen, you can backlight it and still show people the Mountains of Mayhem that lie beyond.
This is assuming your house is still standing after your LLT upgrade...
An AT screen is definitely on my list. For the sake of back row seating, I need to raise the center up at least a few feet which I'd need an AT screen to do as well.
