Edifier today introduced the S550 ENCORE 5.1 Multimedia Speaker System, which features two, 10 - inch
super bass drivers producing 120 Watts each, creating ground shaking audio.
By contrast, the Erato Apollo 7 use a micro-sized dynamic
driver — like a
super tiny version of the
driver in your home speakers or full - size headphones — and, therefore, the
bass on these bad boys is very impressive.
