Introduction
The One marks the beginning of Qln’s truncated cabinet speaker design. The One debuted in 1981 at CES as the first truncated monitor speaker in the world. The shape is an original Qln design combining aesthetic expression with functionality. We are proud to re-introduce this important speaker 40 years later as a testament to Qln’s commitment to advanced design and excellence in sound reproduction.
We don’t draw attention to our technical acumen but rather a piece of furniture that can elegantly find its place in your living room. All the technical parameters for quality sound reproduction are present in our designs but the only role for them is to recreate recorded music from your source. We must not forget that the purpose of a speaker is to recall an original sound event. Making it live again and providing the same emotion we feel when listening to a big orchestra, a string quartet, a rock band, a jazz trio, or vocalist performance. Music lives in the subtleties and nuances we strive to capture.
Qln thinks of speakers as musical instruments. We know that good sound depends on the acoustic chamber just like an acoustic instrument. But unlike music instruments we don’t create sound, we reproduce it.
Qln has always searched for cabinet shapes and proportions that will guarantee exceptional control of internal resonance, perfect acoustics, excellent driver stability, phase response and easy room integration.
The Qln One is that speaker.
Design details
Cabinet
A slanted front baffle provides perfect time alignment between woofer and tweeter. The truncated pyramid cabinet with its minimized baffle area suppresses any standing waves inside the cabinet while also offering improved three-dimensional imaging.
By again basing the cabinet construction around Qln’s unique Qboard® technology, structural resonances are significantly minimized. The bass reflex port with its trumpet shape eliminates air turbulence.
The cabinet is heavily braced for stiffness, but we utilize damping pads to reduce internal resonances which distort sound in the time domain. Natural wool is used to further dampen the internal acoustic chamber. We use minimum damping material and apply it strategically.
Crossover
We utilize the same constant impedance crossover technology found in the Prestige series with fine tuning for the compact two-way design. All coils are air core, and all capacitors are of polypropylene material. All coils are baked so the wires are glued together to reduce internal vibration.
The constant impedance crossover produces an even impedance response that eases the load an amplifier sees (especially tube amps) providing better phase coherence for the driver. The crossover is hard wired for best contact between components with as few contact points as possible. Every component is soft glued to increase damping and minimize vibrations.
Drivers
The drivers have been specifically selected and custom developed by us along with Scandinavian manufacturers to offer the latest in driver technology. The Reed paper cone mid/bass driver with its built-in copper ring in the magnet system and Titanium voce coil offers symmetric drive and higher dynamics in the midrange while concurrently suppressing intermodulation distortion. This results in spectacular voice reproduction, and astonishing micro/macro dynamics uncommon for a compact 2-way speaker design.
The 25mm wide surround tweeter offers superb vocal presentation and excellent imaging in a wide listening area. Its large roll surround, built-in copper ring and textile dome diaphragm provides a flat frequency response above 30 KHz with outstanding off-axis dispersion. The rear acoustic chamber delivers low compression and lowers the tweeter’s system resonance far below the crossover point.
Cables and speaker connectors
Internal cabling is our own specially designed cable optimized for use inside the speaker. All components are carefully hand selected and individually tested for any deviances. WBT pure copper NexgenTM pole screws are used with grip-friendly screws.
