Sonora

Your ears will tell you how right we are.

Introduction
We proudly present a new era in Qln history. The Qln Sonora with fullrange diver with add-on tweeter that plays perfect with low-powered amplifier from 5W and above. Sonora is a classical designed high sensitivity speaker with the latest drive units technology. With focus on easy to drive, low distortion and non resonant technology. The goal is to make an uncomplicated sound that is easy to listen to that respond well to the smallest input signal. The core of Qln filosofi is still there. Time alignment drivers, silent non resonant cabinet that don’t add  coloration to the music. Drive units with extremely light cone that is easy to drive with a small amplifier and give high sensitivity. With low cone mass there will not go deep in small cabinet, so we make a larger cabinet. Then we will have deep clear un compressed natural bass with high sensitivity.

The elegant speaker design is on the inside. Qln Sonora sharing the same DNA as the other Qln speaker. We just made it in a different way.

 

Design details

Cabinet
The cabinet is tuned to make a natural roll-off without any ringing in step response. Cabinet are made of 19mm 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 1,5 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 8” fullrange and treble drivers have been specifically selected and custom developed by industry renowned driver manufacturers and offer the latest in 21st century advanced driver technology. The unique light weight 8” fullregister driver with its built-in copper rings in the magnet system offers symmetric drive suppressing intermodulation distortion. Low losses and large window in the chassis to reduce reflection air noice resulting in industry leading high-end voice handling and astonishing micro/macro dynamics in its hole frequency range. Likewise the 30mm wide surround waveguide tweeter offers time alignment superb vocal rendition and excellent imaging at all listening positions. Large roll surround, built-in copper ring and textile dome diaphragm provides a flat frequency response above 30 KHz. Large rear acoustic chamber give low compression and move tweeter system resonance far from crossover point. The level is a few dB lower that the 8” full range driver and just ass little extra details, resolution and dispersion over 10k to assist the full range driver.
