New Jamo in-wall speaker delivers high-fidelity sonic thrills along with near invisibility

Delivering flagship 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.

Drawing on the same technologies as that have been used to such devastating effect in our award-winning Concert C 80 series the IW 827 LCR is specifically designed for LCR use, meaning that the same speaker can used for Left, Center and Right channel duties in a surround sound system.

As you might have surmised the IW 827 LCR 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 at the bottom. This particular layout ensures great vertical dispersion of sound without the inherent midrange cancellation effect that usually accompanies a regular 2-way LCR woofer-tweeter-woofer layout.

As a result of the layout, with the woofer above and the woofer/midrange below the tweeter, combined with the clever crossover design, the optimal listening angle of the IW 827 LCR is directed slightly downwards. What this means is that the speaker can be placed next to a flat screen TV or otherwise relatively high on the wall while maintaining a perfect performance at the listening height when seated.

To avoid using an inconveniently large enclosure, the optional sealed back-box has been divided in two separate but identical sealed boxes, both lined with damping material. One box surrounds the upper woofer while the other takes care of the lower woofer/midrange. The physical separation means that there’s much less chance of mutual interference between low and mid frequencies.

To ensure the highest sound quality the crossover is equipped with carefully selected high-grade components, carefully positioned and mounted on a thick fiberglass PCB (printed circuit board). Metalized polypropylene film capacitor and metalized film resistors are used in the high-frequency circuit, allowing the tweeter to deliver a crystal clear high frequency reproduction. A low DCR air-core inductor type is used for the woofer/midrange giving low distortion as well as bass purity and clarity

Last but not least gold-plated, heavy-duty push terminals are mounted directly onto the crossover PCB, giving the most direct path for audio signals from an amplifier.

When correctly installed and mated to a quality source amplification the Jamo IW 827 LCR is capable of delivering extraordinary sound quality, a testament to its Concert-series heritage.
