CASCADE TAPERED ARRAY
Place two drivers near each other and interference between the two drivers creates frequency response
errors (called “comb filtering”) for off-axis listeners; you won’t hear the same tonal balance as listeners
who are “on-axis” in the center of the listening area. Polk Audio multi-driver speakers, combat this with
“Cascade Tapered Array” crossovers. One driver is “crossed over” at a lower frequency than the other
driver, filtering out the frequencies where the interference will occur. The Cascade Tapered Driver Arrays
in select Polk multi-driver speakers produce clearer, more detailed sound and uniform tonal balance
throughout the room. The sound is consistently accurate whether the listener is standing or sitting, in-line
or off-axis. See more about Cascade Tapered Driver Array at www.polkaudio.com/catalog/technology/.

A neodymium magnet with low-viscosity ferro-fluid
cooling and a heat sink on the back of the tweeter
assembly, create better power handling and reliability.
Mirrored, triangular cabinets that aim drivers and
tweeters in opposing directions to produce a more
enveloping sound field and wide, lifelike surround-
sound effects.

at the mouth of the port, while allowing simple wall-mounting.
5-way binding posts accept a variety of wiring connectors
and speaker cable up to 10 AWG.

midrange “boom” for clear, natural mids.
Bipole/Dipole switch for the most flexible placement
options and highest performance surround effects.
