Developing a Reference Class On-Wall
The key to this three-way is the crossover frequency
between the 10” and 7” is established precisely where
the wall dip occurs when a woofer is boundary plane
mounted. The dip is the result of an out of phase
relationship at that frequency between driver and
boundary. Attached is a simple illustration of the adverse
effects of a single near boundary.
As professional studios became more compact with modern digital workstations, we
began getting requests for reference grade monitors that could be placed flat against
walls. They needed to be as dynamic as premium floor monitors, low in and profile, and
fire above the workstation desktop height.
Wall speakers are typically utilitarian. Limited by their placement, physical size and build
quality, the sonic results of wall speakers usually qualify them as restricted range surround
channels or background music.
The development of the Silhouette speaker required a new 10” bass driver with a powerful
motor design, yet only 3.5 inches of total depth. A rugged new 10” passive radiator with
compliance optimized to extend response in the compact enclosure. The 4”AMT ribbon and
the 7” silver/graphite midrange/midbass is the same used in several of our towers such as
Focus SE and the Signature SE.
The key to this three-way is the crossover frequency between the 10” and 7” is established
precisely where the wall dip occurs when a woofer is boundary plane mounted. The dip is the
result of an out of phase relationship at that frequency between driver and boundary. The
