COMPACT FLUSH-MOUNT SPEAKER
PERFECT FOR CEILING AND WALLS
A round flush-mount speaker can give the maximum performance in the
smallest space. Its shape is ideal for ceiling mounting, and matching the shape
of round light fixtures. Yet many round speakers are designed to the lowest
standards of performance allowable. Not so with the Snell AMC680r. The
AMC680r utilizes our “Directed Power” tweeter, a custom waveguide, that gives
the sound of a large full-range speaker. This deisgn feature alone surpasses all
other round flush-mount speakers. The “Directed Power” tweeter gives near
constant beamwidth over a much wider range of frequencies than “pivoting eye
socket” tweeters. By aiming it at a 20 degree angle we can direct the energy
toward the listening position and assure clarity and imaging that is remarkable
for an in-ceiling speaker. Alternatively, when used as a surround speaker the
system can be aimed away from listeners so that energy bounces off of adjacent
wall surfaces to give a desirable increase in diffusion. The large area of this
waveguide also reduces rearward bounce off of the woofer cone for a much
smoother tweeter response allowing a lower crossover point.
The crossover network used with the AMC680r is much more complex than in
competitive models for highest possible performance. As with every Snell
speaker, the AMC680r is hand tuned by our technicians to ensure that each pair
sounds as well balanced and detailed as our design engineers intended.
