There are two choices for installation.  A "dog frame" allows for installation on standard drywall.  In this case, a mounting plate contains the speaker wire connections.  These are perfect options for in-wall substitute, where cutting the drywall is not an option.

The speakers contain a 5.25-inch Kevlar woofer and a 1-inch coaxially mounted, pivoting silk dome tweeter.  There is no information on price at this time.
