Difficult to see how small cone can make this much bass but it does! Obvious why Steve calls them High Definition Towers because they definitely are. Every sound on the recording is evident but all musical and not harsh or piercing to the ear. Bass fools you because it is not bloated and overhung in the room. It just plays and stops as it does live. All around great speaker as expected since Says he uses it voice his products. No higher praise needed?     Pick these up for a bargain price!

PM for questions. Obviously not a pro photographer but will try to clarify if you have specific question/concern
