Tonight, we switched between the two subs for War of the Worlds - specifically the lightning scene then the machines break through the ground scene.
In the machines coming through the ground scene, I was worried, both times, that I would be calling for new drivers.
Both subwoofers were pretty potent - louder than I care to listen, with rare exceptions. That being said, they both would require multiple units to achieve that elusive "reference" level in our 4000 ^ 3 foot basement.
In this case, the SVS was a bit more forceful in energizing the room than was the Hsu - and these two scenes need LOTS of horsepower. The SVS, subjectively, has a bit more HP in the deepest bass.
The units were set up as follows: Two ports open, 16 Hz for the Ultra and Turbo installed, 16 Hz for the VTF-3 HO.
Next up is posting the graphs - and watching Return of the King.
Will the graphs match the subjective ?
