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.
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.
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.
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.
Our 184mm Kevlar® mid-woofer was custom developed by Qln together with industry renowned Danish driver manufacturer Scan Speak and offers the latest in 21st century 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.
Likewise, the unique Illuminator tweeter offers superb vocal rendition and excellent imaging and extension 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 eliminates any reflections and resonances.
Cables and speaker connectors
Internal cabling is our own and specially designed and produced in Sweden. It consists of 12 solid core pure copper wires wrapped around a polypropylene core with polypropylene isolation, bounded with a high damping camel body. All components are carefully hand selected and individually tested for any deviances. Speaker terminals are WBT Nextgen® connectors with minimal connection materials made of silver/copper for best connection to the speaker resulting in lower distortion.
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!
