At the heart of the new in-ceiling and in-wall LCR models is a unique Inverted
Dual Concentric (IDC
®
) pivoting midrange/tweeter module with up to 18
degrees of play. Speakers can be discreetly positioned, and then the sound can
be directed into the desired listening zone by pivoting the IDC
®
driver module to
maximize performance. These models are true 3-way designs and offer superior
performance and exibility over typical 2-way or xed angle speaker designs.

Inverted Dual Concentric Driver module
Only Monitor Audio offers the innovative IDC
®
driver module. Our special
inverted 4” midrange driver provides superior dispersion, while enabling the mid-
range cone and tweeter dome to be set as far forward as possible, allowing
clear acoustic ‘sighting’ of the desired listening zone and negating undesirable
diffraction effects. It’s impossible to avoid diffraction effects with two-way
designs where signicant vocal band information comes from a bass driver set
3” to 6” back from the speaker grille.
