Premium Bass, Small Space, No Face
Polk's patented PowerPort bass venting system greatly enhances the
smooth low-end response in this easy-to-place, single-woofer in-wall
speaker. Recommended for use as left and right front channel speakers,
stealth side or rear surround speakers in an RTi theater system setup,
or for superior dynamics in practically invisible multi-zone music
systems. Virtually-flush mounting with a minimal-flange design means
this speaker never attracts attention by its looks, only by its
Vanishing Series RT speakers are timbre-matched to Polk RTi speakers
to insure utterly seamless blending from speaker to speaker in systems
that combine traditional and built-in speakers.
Superior imaging and clear, lifelike detail is revealed by the
responsive silk dome tweeter in Vanishing RT speakers; it's set in a 15°
swivel housing, for more direct high frequency control, excellent
off-axis imaging and more placement flexibility.
Vanishing Series built-in speakers feature our exclusive
wafer-thin Sheer-Grille™, a magnetically-secured grille that protrudes
only 7mm from its surroundings. Sheer-Grilles have nearly transparent,
ultra-small perfs, and are acoustically inert, for dynamic, unimpeded
sound and more uniform coverage, even in larger rooms.
Painted to match your décor, Vanishing Series built-in speakers are virtually indistinguishable from their surroundings.
Reflective surfaces in rooms can make sound brighter and cause
image distortion. Engaging the Vanishing reflective room compensation
feature (by selecting the low setting) lowers the tweeter level to
compensate for reflective surfaces. Vanishing reflective room
compensation is a custom audio control that cuts the level only in the
4-5kHz range, exactly where reflectivity destroys sound quality. Outside
this narrow 1kHz band, the tweeter retains its detailed and accurate
high frequency response, for no loss of realistic musical details.
If positioning limitations demand that your loudspeakers be
installed closer than 2 feet from side walls, the proximity of the
surface can result in a response bump between 50 and 200Hz. This can
create a ‘boomy' sound. The Vanishing wall distance toggle switch is a
custom audio control that adjusts the crossover to flatten response and
tune out boominess, without sacrificing deep bass response, for more
lifelike sound and more flexible placement.
PowerPort bass venting is Polk's patented design for smoothly
transitioning the air flow from the port into your listening area,
eliminating turbulence and distortion, for bigger, more efficient, deep
Easy one-cut, drop-in installation puts built-in audio within
reach, with Perfect Fit templates, a precision flange, and (available)
pre-construction brackets; achieve secure, vibration-free efficiency
with a simple turn of the patented Rotating Cam system.
