How do the Q Acoustics 2020i sound? In short, excellent. Enjoy big sound from a medium sized speaker that exudes quality. The beautifully finished, low resonance cabinet encapsulates the 25mm ferro-fluid cooled tweeter & precision engineered 125mm bass driver to produce a speaker with extended bass, an open mid-range, astonishing transient response & exceptional high frequency clarity. The 2000ST or 2000WB allow the 2020i to be stand or wall mounted.
