Core Concert Series technologies, such as Decoupled Tweeter Technology (DTT), WaveGuide, Hard Conical Cones (HCC), Active Impedance Correction (AIC) and solid aluminum center plugs, are found in these high-performance models.

The IW 827 LCR is a 2.5-way design with a 1-inch DTT silk dome tweeter located between the 7-inch woofer and a 7-inch midrange/woofer - both featuring high-end fibreglass/honeycomb composite drivers. This design, coupled with a crossover, achieves excellent vertical sound dispersion without the midrange cancellation that can happen in a traditional two-way speaker's woofer/tweeter/woofer layout.

The driver configuration gives it a slightly downward optimal listening angle; in other words, it can be installed next to a flat panel TV or alone, relatively high on a wall, and still deliver optimal audio to those seated in the room.

For installations that require a sealed back box, the speaker has an available two-part enclosure. The halves are identical and are lined with damping material. By using separate boxes for the upper woofer and lower woofer/midrange, the possibility of mid- and low-frequency interference is reduced.
