Since you already have an HSU sub you could simply use the Ventriloquist system they have. For a bedroom this would be more than sufficient. I am selling my set since my new media room allows for larger speakers. If not interested for $199 then good luck in your search.
Selling (2) Energy CB-20 and (1) CC-10 - perfect condition - will include (2) Omnimount 20.0 wall mounts.
