Ceiling Speakers
A new house is a great place for a home theater.
But, in many cases the room layout makes it difficult
for ordinary speakers to track with the video motion
across the sound stage. When using built-in speakers
for video in a corner or an entertainment cabinet, it
takes away the flat surface needed for correct sound
propagation.
Enter Proficient’s LCR Ceiling Series speakers. With
this revolutionary design you can get imaging and
staging that would be lost with regular, down-firing
ceiling speakers. We accomplish this because our
woofers are set at a 15˚ angle. The critical high and
midrange frequencies are then pointed toward the
listener, not the floor. So, when your video tracks
left to right, the sound tracks right along with the
video. You can even use them for rear and side
surrounds in a 5.1 or 7.1 system.
The new C870 is our flagship LCR ceiling speaker
and is designed for larger theater rooms and highend systems. They feature an 8" Kevlar woofer,
1" aluminum dome pivoting tweeter and 175 watt
power handling. Plus, you can tailor bass and treble
up or down thanks to front-mounted contour
switches. The C870 speakers will look good and
sound great for years to come.
Quality-built, of course. Exactly what you’d expect
from a premium brand like Proficient.
