Here's my situation: looking for a sub to put in my newly added living room. I will be using KEF's new T series speakers for my front and rear duties, but I don't think their slim sub of the same series will do for my room. The room measures 14.5' wide by 20' long and is a fairly open floor plan. Listening will be mostly movies with occasional music. I'm looking for something that won't be lost in the open design of the room. I have been looking at offerings from HSU and Velodyne, but the more I read the more confused I get. Thanks in advance for your thoughts.
