Qln One Hi-End speaker for small rooms


The One marked the beginning of Qln’s truncated pyramid design, debuting in 1981 at CES as the first speaker of its kind in the world. The shape is an original Qln design combining aesthetic expression with functionality. The Qln One has been the little brother of the Signature since the Signature was introduced in 1989.
When we updated the Signature in 2022, preparations began for the 7th generation of the Qln One speaker. We are proud to introduce this new speaker as a testament to Qln’s commitment to advanced design and excellence in sound reproduction.

Qln One
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 to recreate recorded music from your source. We must not forget that the purpose of a speaker is to recall an original sound event. Our goal is to provide the same emotion you feel when listening to a big orchestra, a string quartet, a rock band, a jazz trio, or vocalist performance. It is this pursuit along with music’s subtleties and nuances that we strive to capture.
The design goal for the new Qln One was not to make a small speaker sound impressive in large rooms but to make a mini monitor that works in a smaller room with the Qln quality standard.
So, if you are looking for the highest level of performance from a speaker in a small or difficult room, the Qln One is that speaker.


Our technology


Cabinet design
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 designing the cabinet construction with 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 and Qboard® to reduce internal resonances which distort sound in the time domain. Natural wool is used to further dampen the acoustic chamber internally. We use minimum damping material and apply it strategically.

The proprietary 5,5” mid-woofer is a custom designed sandwich paper cone offering state of the art 21st century driver technology.

The specially coated sandwich paper cone bass/midrange driver with under hung magnet system (where the voice coil is in the magnet gap all the time) forms a completely linear motor system. This allows for open air flow without any compression or turbulence resulting in micro details and the absence of acoustic noise commonly found in most basket designs. A built-in copper ring in the magnet system offers symmetrical drive, and lower voice coil inductance producing higher dynamics in the midrange while also suppressing intermodulation distortion. All these technical innovations result in astonishing micro/macro dynamics from a 2-way speaker design.

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.


The crossover for the Qln One is comprised of very few components and arranged in a very special way. The core crossover has just two components with few adjustments.

This makes the Qln One play lively with a big sound from a small enclosure.
The crossover is hard wired with as few contact points as possible between components. Every component is soft glued to increase damping and minimize vibrations.


Cables, speaker connectors and internal damping. 
Internal cabling is our own special design produced in Sweden. Solid pure copper core wrapped around a polypropylene inner layer 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 use a small amount of synthetic fiber to get the right density.
