FEATURES AND BENEFITS
(In-Wall and In-Ceiling Models)
• Kevlar
®
composite woofer – Woofer construction combines
exceptional rigidity and lightness to provide the perfect linear
movement needed to reproduce dynamic, tight bass and
incisive midrange frequencies
• AeroNylon tweeter diaphragm – Aerospace-grade
nylon tweeter diaphragm combines very low mass and high
tensile strength to provide crystal-clear treble response and
exceptionally accurate tracking of even the most challenging
musical transients
• AutoSurge™ circuit protection – Built-in AutoSurge
protection responds to potentially destructive power peaks
automatically and resets after the event, helping prevent
speaker damage
• Advanced phase/time alignment guide – A precise
phase/time waveguide is used to properly align sound without
mis-aligning the tweeters – a problem with many adjustable
in-wall speakers – in order to provide extremely accurate
stereo imaging
• Precision dividing network – The dividing network (or
crossover) used in all Spec-Grade Sound speakers is made of
high-spec components to ensure total audio signal electronic
integrity up to the last microsecond before the signal is
converted into sound
• Inert mounting frame with “dogleg” installation
points – To eliminate any transmitted vibrations that could
color in-wall or ceiling sound quality, Spec-Grade Sound
speakers rely on a baffle-frame assembly incorporating
higher-density plastics and a series of adjustable “doglegs”
to rigidly clamp the speaker to the wall or ceiling material
