Speaker compare - TB TO-2008S vs Scale Sound Systems

A comparison of two different speakers. The TB speaker is very large and required that I remove a significant portion of the weight (ScaleTrains Dash 9), as well as thin out the speaker housing.
The Scale Sound Systems speaker is built specifically for this model (Atlas C40-8W) and is a simple plug and play install. They are currently not available.
Listen to both and see what you think. My goal was to obtain bass like the Scale Sound System speaker offered, since that was the best I had heard.
Both locomotives are the same distance from the mic (shotgun mic) and both at the same volume.
