QLN Sonora
Beschrijving / Description
The cabinet is tuned to produce a natural roll-off without any ringing in step response. The cabinet is made of 19mm thick HDF-board with internal damping pads for minimizing cabinet material resonances. It is heavily braced for "stiffness", and the damping pads role is to ensure that the cabinet does not "store" sound and interfere with the correct restitution of the time domain. Natural wool is used for internal acoustic damping because it sounds best, and it provides damping over a wider frequency spectrum. Further, the wool is "loose packed" so we don't store sound in the damping material. We however use a strict minimum of damping material, and apply it only where it provides the most benefit -- in the center and the middle of the cabinet where the air speed is at its maximum. This way, we are able to apply a minimum of damping material to achieve maximum damping of unwanted internal sound waves.
The 1.5 way crossover, with its minimum number of components, is hardwired and features 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.
The 8 inch full-range and treble drivers have been specifically selected and custom developed by renowned industry driver manufacturers, and offer the latest in 21st century advanced driver technology.
The unique light-weight 8 inch full-range driver with its built-in copper rings in the magnet system offers a symmetrical drive capability, thus suppressing intermodulation distortion. Low losses, and a large port in the chassis further reduces reflection of air-induded noise, and results in industry leading high-end vocals restitution, as well as astonishing micro/macro dynamics across the entire frequency range.
Likewise, the 30mm wide surround waveguide tweeter offers precise time alignment, superb rendition of vocals, and excellent imaging at all listening positions. A large roll surround, a built-in copper ring, and a textile dome diaphragm, all combine to provide a flat frequency response above 30 KHz. The large internal acoustic chamber allows for low compression, and moves the tweeter's system resonance far away from the crossover point. Its output level is a few dB lower than that of the 8 inch full range driver's. This allows it to just add a little extra detail, resolution and dispersion over 10k to assist the full range driver.
