Sounds like you need more drivers to load the new space better. Towers or sub or both. Sounds like a system overhaul. Choices ahead. smile

Since it isn't a dedicated space I would vote towers and center. Bump your monitors to surround duty and get a pair of Phil 3s and a center. Those look impressive.

Otherwise your M80s/100s and 160 sound like a good option.

Depends where you think you are out of gas now.
