KEF Q10 (1993–1996)

Name: KEF Q10
Brand: KEF

A compact bookshelf speaker from KEF's Q series, with a coaxial Uni-Q driver and magnetic shielding for CRT compatibility

Overview

The KEF Q10 is a bookshelf loudspeaker built from 1993 to 1996 as part of KEF's Q series. It's a compact two-way system built around KEF's Uni-Q coaxial driver. The Uni-Q puts a 16 cm polypropylene cone woofer and a 1.9 cm soft dome tweeter into a single point-source array. The acoustic centers of both drivers line up in depth, which improves phase coherence and gives a more focused soundstage. The enclosure is bass-reflex with a 9-liter internal volume. It has magnetic shielding so it won't interfere with CRT displays, which makes it usable near older televisions or monitors. It was priced at ¥26,000 per unit around 1994, a space-efficient speaker that kept to KEF's engineering principles.

Design

The Q10 uses a Uni-Q coaxial driver with a 16 cm polypropylene cone woofer and a 1.9 cm soft dome tweeter. The diaphragms are aligned in depth for better phase coherence. The tweeter's magnetic circuit is neodymium iron boron, a material with ten times the energy of ferrite, so the tweeter can be more compact. The crossover network is mounted on the rear terminal panel and built with independent wiring to balance frequency response. The enclosure is a bass-reflex design finished in ash black.
