Good Design The theory of
According to Quad’s philosophy
a good loudspeaker should add
nothing, nor remove anything from the
recorded sound. Many loudspeakers
on the market adhere instead to a
philosophy of extending the high
and low frequencies to make an
artificially ‘impressive’ loudspeaker.
Such an approach can sound good in
the dealer’s demo room but is quickly
fatiguing and often masks the more
subtle nuances of a recording.
Our engineers focus instead on the
audible range, ensuring as smooth
as possible an integration between
bass and treble. This is the most
crucial region of any loudspeaker’s
frequency response. The human ear
is at it’s most sensitive through the
vocal range of frequencies, which
is also the range that moving-coil
loudspeakers crossover from using the
mid/bass driver to the high frequency
tweeter.
The art of a good crossover is
simplicity, but for other manufacturers
the crossover needs to compensate for
slight miss-matches between bought
in components – Quad doesn’t buy
in components, we make them all
in-house, so our loudspeakers are
designed in perfect synergy. Our
crossovers are extremely simple and
retain all of the precious mid-range
detail and purity that can so easily
be lost. We use the highest quality
components and windings to ensure
nothing is compromised.
