Introduction
We are pleased to introduce the Qln Prestige Five – an
unprecedented 2.5-way, floor standing loudspeaker that marks the
advancement and continuation our highly successful Prestige series.
Decades
of design experience has proven time and time again that what separates
a good loudspeaker from an exceptional one is the midrange. For the
Prestige Five, we spent years developing a new, superb sounding 184mm
Kevlar® mid-woofer that conveys instruments and vocals with
unprecedented clarity, resolution and naturalness. From there, we
listened for 1000s of hours to decide on the exact woofer and tweeter to
carefully balance the music spectrum and housed them in their own
non-resonant and optimally-tuned enclosures.
Prestige Five
The
Prestige Five exemplifies a timeless combination of form, function and
performance. It is the fruit of Qln’s four decades of speaker research,
development, design and construction. A meticulous selection of matched
components ensures every part of the speaker synergizes perfectly
together. This was an extensive process involving multiple systems and
genres of music over a long period of time to verify consistency. When
you experience the Prestige Five, we are highly confident that our
design approach and efforts will make perfect sense to your ears.
Your ears will tell you how right we are.
Our technology
Cabinet design
Our
slanted baffle provides perfect time alignment between woofer and
tweeter and the truncated pyramid cabinet top with its minimized baffle
area suppresses standing waves inside the cabinet as well as baffle
effects which in turn improves 3D imaging. The cabinet construction is
based around Qln’s unique Qboard® technology, where structural
resonances are eliminated. The bass reflex port with its trumpet shape
at both ends eliminates air turbulence. The Cabinet is de-coupled from
the floor via solid feet with cones and pucks constructed out of hard,
high damping materials.
Woofer
Our 184mm Kevlar® mid-woofer
was custom developed by Qln together with industry renowned Danish
driver manufacturer Scan Speak and offers the latest in 21stcentury
advanced driver technology. It features an under-hung magnet system were
the voice coil is in the magnet gap all the time, resulting in a
totally linear motor system. Together with the extremely open basket,
this allows for air flow without any compression or turbulence which
offers more micro details and lowers acoustic noise typically found in
standard baskets. Built-in copper rings in the magnet system offers
symmetric drive and lower voice coil inductance, which results in higher
dynamics in the midrange while also suppressing intermodulation
distortion.
The long stroke, 184mm hard cone woofer with the same
unique magnet system as the mid-woofer works harmoniously with the inner
volume of both drivers to produce well-controlled, powerful bass down
to 26Hz.
Tweeter
The advanced 25mm wide surround tweeter
offers remarkable vocal reproduction and excellent imaging at all
listening positions. Its large roll surround and textile dome diaphragm
provides a flat frequency response above 30 KHz with outstanding
off-axis dispersion. The unique AirCirc magnet system and its rear
chamber eliminate any reflections and resonances.
Crossover
The
constant impedance crossover in the Prestige Five is hardwired with
non-inductive capacitors bypassed with copper film capacitors for the
tweeter section. For the mid-woofer, we strictly use flat foil
inductors. All components are fastened with soft damping glue and
inductors are baked to avoid any internal component and filter
resonances. Precision metal film resistors with high power handling
capabilities, low noise, and temperature stable performance are used,
resulting in perfect timing within the crossover and low noise
throughout the entire frequency range.
Cables, speaker connectors and internal damping.
Internal
cabling is our own special design produced in Sweden. Solid pure copper
core wrapped around a polypropylene core with polypropylene isolation,
bounded with a high damping acoustic shield to minimize acoustic
feedback. All components are carefully hand selected and individually
tested for any deviances.
Speaker terminals are WBT Nextgen®
connectors made of the highest grade silver plated copper with minimal
copper mass for low energy storage lowering distortion and offering the
purest contact to the speaker cable.
For internal acoustic damping we
use real wool. Wool is the best material for internal acoustic damping
but we need a small amount of syntetic fibre to get the right density.
Non-Resonant Behavior
Every
part of the speaker has one thing in common – non-resonant behavior.
From connectors, cables, crossover components, speaker drivers, the
cabinet, and even the damping feet are all characterized by non-resonant
behavior. This suppresses disruptive noise, vastly improving dynamics
and preserving silence between tones as a result of the low noise floor.
The Prestige Five presents a more dynamic and relaxing sound with
remarkable clarity. Nothing is added – just pure music!
Finally
All
parts have one thing in common. Non-resonant behaviour from connector,
cables, crossover, speaker drivers through the cabinet with the damping
feet.
This suppresses disturbing noise, offering more and better
dynamics with better silence between the tones thanks to the lower noise
floor.
The Prestige Three presents a more relaxing sound with remaining details – nothing is added – just pure music!
