How much difference is there between the “in-air” testing/performance of Onsia, and, the In-Wall finished sound?
The difference is enormous. The In-Wall speakers are designed specifically to be covered with drywall compound and integrated into your wall system. Even after installation, it takes up to 40 hours of playback for the speaker to break in. Onsia In-Wall speaker panels are pre-stressed (curved) to maintain linearity upon installation. This means that the panels will have “resonance” and will not have a full-range, rich sound until after they are installed in your wall or ceiling. The speakers have been engineered to fully perform only after they are integrated into your wall or ceiling, with drywall compound and paint or wallpaper over the panel.
