Product details

Overview

What is the KEF Ci200QSB-THX?

The KEF Ci200QSB-THX is an 8-inch (200 mm) in-wall or in-ceiling subwoofer that runs either in passive mode with its crossover on, or in active mode with the KEF KASA500 amplifier. KEF lists 40 Hz to 100 Hz in passive mode and 18 Hz to 140 Hz in active mode. Installers in the UAE specify it for home cinema rooms that need low-frequency output without a floor-standing subwoofer.

The KEF Ci200QSB-THX is an architectural subwoofer with a 200 mm (8 in) driver. KEF lists two operating modes: passive (crossover on, 6 Ω, 10 to 150 W recommended amplifier power) and active (driven by the KEF KASA500 amplifier).

  • Installation

    KEF lists a cut-out of 238 × 238 mm, a mounting depth of 101.6 mm from the surface, and ceiling thickness from 6 mm to 40 mm. An optional rough-in frame, the RIF200S, is available.
