@maxwave, to an extent that is how it works ... the area of a driver (circular) increases exponentially with radius but a greater linear displacement also helps to generate bass at low frequencies.
The cone shape is also a factor.
One > two drivers double cone area and add to symmetry (power output).
Two > balances internal energy.
If you get hung up on 'driver envy' consider the fact that @ 40 Hz the wavelength is 8.6 M or about the same dimension of an interior wall (large room).
@stereo5, sealed enclosures have relatively good output response and if
given good power will perform very well.
KEF produces extreme HiFi Gear and I personally would not hesitate to trust in the engineering some.
A single sub is smart ... not a mistake.
+1 @nonoise, good review article btw.
+1 @ozzy, Hsu is also very good and possibly a more affordable model.
