My "theater" is anchored by arros. Its a small room as well and I do obviously use a sub with them, and I am very pleased with the results. I also do not use a center speaker as I don't feel I need it with the fantastic imaging of the arros. Like you, I do not need my house rattling at the foundation for a moving musical or movie experience either.
Totem Home theatre
I am interested in those who have used totems for Home THeatre. I love them but hard to imagine thiose little things handling the dynamics and volume. I am not a loud listener, but also have small room. Particularily interest in Arro based system. Have a well matched sub, but wouln't mind comments.
