Delivering fl agship standard sound quality from in-wall speakers is a challenge, but Jamo believes it has
achieved just that with its new Concert-series derived Jamo IW 827 LCR.
Specifi cally designed for LCR use this speaker is equipped with optimized drivers hailing from the Jamo
C 800 series and therefore makes use of all Jamo’s core technologies. These include Decoupled Tweeter
Technology (DTT), WaveGuide, Hard Conical Cones (HCC), Active Impedance Correction (AIC) and solid
aluminum woofer/midrange Centre Plugs.
The IW 827 LCR is a 2½ way system with a 180mm/7in woofer positioned above a 25mm/1in tweeter while
a 180mm/7in woofer/midrange sits underneath. This layout ensures great vertical dispersion of sound
without the midrange cancellation effect of a regular 2-way LCR woofer-tweeter-woofer layout. As a result
the optimal listening angle of the IW 827 LCR is directed slightly downwards which means the speaker can
be placed next to a fl at screen TV or otherwise relatively high on the wall.
For ease of installation and maximum sound quality the optional sealed back-box has been divided in two
separate but identical sealed boxes, both lined with damping material. The crossover features high-grade
components, carefully positioned and mounted on a thick fi berglass PCB – equipped with gold-plated,
heavy-duty push terminals - to give crystal clear high frequencies and a pure, distortion-free bass.
