In-ceiling speakers offer an enticing
alternative to traditional box speakers
by introducing the possibility of playing
music in rooms where precious floor
space will not allow, or where the look
of the room may be negatively affected
by a standard box loudspeaker system..
With a lot of in-ceiling speakers
however, these possibilities can come
at the cost of the overall sound quality.
Sadly, many of the in-ceiling products
available today seem to focus only
on the convenience of the product
category, and leave a lot to be desired
when it comes to audio performance.
DALI believes that in-ceiling speakers
and true Hi-Fi can go hand in hand,
so the PHANTOM E Series of speakers
delivers on both stylish design and
fantastic sound.
When designing an in-ceiling speaker,
there are a couple of things to be very
aware of:
All install speakers are mounted into a
large surface, such as a wall or ceiling.
This situation can, if used correctly,
help extend the bass reproduction by
working with the surface, and including
it in the speakers baffle area. The
downside of this is that the surface
material is often not of the equivalent
level of quality when compared to
the materials used when designing
cabinets for box speakers. To counter
this, the mounting system and front
baffle of a quality install speaker needs
to be extremely rigid.
Another unknown is the cavity space
behind the install speaker. This area
can be well dampened and thereby
absorb many of the lower frequencies.
On the other hand, there can be no
damping at all, and standing waves
can have a very negative effect on the
speakers bass reproduction. An open
back install speaker must be built to
handle both situations and keep the
driver under control.
DALI has more than 30 year experience
in building and designing traditional
loudspeaker cabinets and driver units.
This knowledge has been invaluable
in the design and manufacture of the
PHANTOM E series, and has helped
ensure that this brand new open back
in-ceiling speaker delivers on all of
DALI’s sound principles.
