The Sonance Invisible model IS4 is simple to install and sets a new acoustic standard for the invisible speaker category. It’s a 3-way design that offers more low end, better mid-range clarity, high frequency extension with up to 170 degrees of dispersion. When mounted in a ceiling with low profile lighting fixtures, the resulting high-fidelity sound will amaze and thrill potential home buyers as they tour the model homes'. Invisible speakers do not have to be specified for the entire home, although many dealers have done this for some of their more design-focused clients. Some dealers will specify Invisible for formal dining rooms and even better fidelity cone/dome direct radiators for home theater rooms and studies. The key to success is to arrange for a demo of both types of speakers and let the client decide for themselves. Letting the client hear their new Invisible speakers for the first time after the paint has dried can be risky.
