Unlike many subwoofers in the
market the DALI SUB E-9 F has
been engineered to perform equally
well on both music and movies. It is
important to us that a subwoofer is
capable of rendering a performance
true to the input signal. Therefore a
DALI subwoofer is everything but a
‘boombox’.

Over the years DALI’s engineers have
developed a set of sound design
principles. Today these are applied
in the creation of basically any DALI
speaker. Naturally our subwoofers must
be able to enter into any setup without
sacrificing the purpose of providing
wide dispersion, time coherent and
low-loss performance.
