Smart Features:

Slim Bezel Design
Boston's unique Slim Bezel Design provides interior designers and consumers the
look that blends with a room's destinctive design. Slim Bezel Design also offers
an installer-friendly wide mounting flange to cover any imperfections in the cutout
hole and magnetic grilles for easy finish work.

Boston Kortec® Tweeter
Boston's exclusive Kortec tweeter utilizes a silk-like dome backed by a stiff material
to provide smooth high-frequency reproduction and stability at high volume levels.
The tweeters also pivot to allow installers to aim the tweeter toward the prime
listening position making speaker placement less restrictive

Rugged Pivoting Mounting Arms
All Boston custom speakers include pivoting mounting arms (or sometimes called "doglegs")
that not only make installation a snap but also they are built to withstand the
force imposed by even the most powerful screw guns.
