Qubic 10

Your ears will tell you how right we are.

Introduction

The goal of the Qln Qubic 10 was to create a speaker with a combination of visual timeless design and the ability to make you just listen to music and not to the technical solutions involved.
Where others show off their technical solutions, we try to hide them and just present a piece of musical furniture that can be nicely placed in your living room. All the technical solutions are present, but the only role for them is to recreate the 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 emotions we feel when listening to a big orchestra, a string quartet, a rock band, a jazz trio or just a vocal with a piano.
This is why Qln thinks of speakers as musical instruments. We know that good sound depends on the acoustic chamber – just like in a string instrument. But opposite to music instruments we don’t create sound, we just 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 integration in rooms.

As always, here at Qln the total functional design is the result of the demands for the resulting sound.

 

Design details

Cabinet
The cabinet is tuned to make a natural roll-off without any ringing in step response. Cabinet are made of 21mm thick HDF-board with internal damping pads for minimising cabinet material resonances. Cabinet is heavily braced to give stiff cabinet and the damping pads make in non resonant so the cabinet don’t store sound in the time domain. Natural wool is used for internal acoustic damping because it sond best and have a wider frequency damping  of the internal sound. It is loose packed so we don’t store sound in the damping material. We use minimum damping material and apply it where it do the most use, in centre and middle of the cabinet there air speed is at it maximum. Then we can apply minimum damping material to achieve  maximum damping of the internal sound.

Crossover
The 2 way crossover with it minimum number of components is hardwired with high-end Mundorf capacitors and baked air coils to avoid any internal component and filter resonances. The result is perfect timing within the crossover and throughout the entire frequency range.

Drivers

The drivers have been specifically selected and custom developed by industry renowned Danish driver manufacturer Scan-Speak and offers the latest in driver technology. The fiber cone mid/bass driver with its built-in copper ring in the magnet system offers a symmetric drive and higher dynamics in the midrange concurrently suppressing intermodulation distortion and resulting in industry leading high-end voice handling and an astonishing micro/macro dynamics unheard in a compact 2-way speaker design.
The 25mm wide surround tweeter offers a 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 an outstanding off-axis dispersion. A large rear acoustic chamber gives low compression and lower the tweeters system resonance far below the crossover point.
