KEF Q75

Commentary

A toll-boy type speaker system that employs the fourth generation UNI-Q driver.

In the lower range, it is equipped with a racetrack bus unit, an elliptical cone woofer newly developed by KEF, and a passive radiator of the same diameter.
This unit has a heat sink attached to the center cap.

16cmUNI-Q driver, a coaxial type unit unique to KEF, is installed in the middle and high range.
The UNI-Q driver consists of a 16 cm polypropylene cone type woofer and a 1.9 cm soft dome tweeter.
The tweeter uses neodymium iron boron, which has 10 times the magnetic force of ferrite, and ferrofluid, a special coolant with enhanced power handling. This realizes ultra-small size and high performance of the tweeter. This enables fine adjustment of the position of the tweeter in the direction of the vibration axis, so that the phase of the two units at the crossover point is perfectly positioned.
In addition, this unit adopts the latest version of the fourth generation utilizing UNI-Q technology developed by the latest reference series. By adopting half-clear diaphragm material and tweeter pure silk material, the sound connection from the low range to the high range has been further improved.

It has a perfect magnetic shielding design and has no adverse effect on cathode ray tubes, etc.

The network section is designed by computer acoustic analysis.

The enclosure bass reflex port has a geometric form.
In addition, the exterior has a rosewood veneer finish.

A speaker terminal for bi-wiring and bi-amplifier drive is adopted.

Spike for installation is included.
