So, I went for some rap. I broke out Shoanna Z's album "Racism Exposed", "NBC, ABC, CBS, CNN, AKA Left Wing Trickery". This track features massive energy at 40Hz. While the 5WS did not have the authority of larger subs on this opening passage, it is one of the tightest and most "impactful" subwoofers that I have ever used. I would love to hear this again with eight of these bad boys instead of just four.

Now I wanted to see what kind of "Jolt Factor" the Utopia 5WS subwoofer could reproduce. (The term was coined by my friend and teacher Rob Greene; he uses it to describe how well an audio system can jolt you by a surprise hit of volume.)
