This is Sausalito Audio’s first CSA waveguide with a more conventional form factor.  While the internal geometry is the same as other CSAs, the mouth of the waveguide has been modified so that it can mount on a flat surface — like a more conventional waveguide.  While we were thinking of in-wall speaker applications, this could certainly be used in other speakers.
