T W E E T E R S

WA R N I N G : Do not operate the tweet­ers without crossover networks.
Damage to the tweeter from therm a l
overload will result without the pro t e c­tion provided by a crossover and will
void your warr a n t y.

The Polk Audio Signature Reference
t w e e t e r, in component setup, offers
two mounting options for installation
f l e x i b i l i t y . (See Figure 6)

N O T E : If you choose to operate the
system with an active cro s s o v e r, the
c rossover frequency for the tweeter
must be greater than or equal to 3.5kHz
with a minimum 3rd order (18dB/octave)
slope. Please note that the tweeter
could be damaged at excessive listen­ing levels. For the best tweeter pro t e c­tion, use the crossovers supplied with
the systems.

TWE ET ER L EV EL

The jumper levels inside the crossover box
adjusts the level (volume) of the tweeter
relative to the mid/woofer. Start with the
jumper in the “0dB” position and listen.
If you want a “brighter” sound, move to
the left position, “+1dB,” and listen again.
The “+1 dB” setting provides the gre a t e s t
amount of tweeter output. -1.5dB and

-3dB reduce output to a greater degree.

(See Figure 10)

POL AR ITY /
B L E N D I N G

If it seems that the tweeters and drivers are
not “blending” seamlessly, change the polar­ity of both tweeters by reversing the positive
(+) and negative (-) tweeter wires at the
c r o s s o v e r. Reversing the phase of the tweet­ers will usually optimize the blending of the
system components when the tweeters and
drivers are located far apart from each other.

Your speakers will work well with a variety
of electronic components. As little as 25
Watts (RMS) per channel will deliver ade­quate listening levels in most cars. If you
intend to play your system at loud listening
levels, more power is necessary to achieve
the best perf o rmance. Consult your Polk
Audio Dealer for specific re c o m m e n d a t i o n s .
We recommend using an external power
amplifier that has a power rating of 50 - 150
Watts per channel to get the best possible
p e rf o r m a n c e .

SAF E L IM ITS
OF O PE RAT I O N

Your Polk Audio loudspeakers are made with
the highest quality materials for years of
t ro u b l e - f ree perf o rmance. However, damage
to loudspeakers can occur when an amplifier,
re g a rdless of its wattage, is made to play at
higher listening levels than its power can
cleanly produce (usually beyond the “1 to 2
o’clock” position on the volume contro l ) .
This results in very high levels of audible dis­t o r tion, originating in the amplifier, which
adds a harsh, gritty sound to the music.
C o n t r a r y to popular belief, a speaker is more
likely to be damaged by trying to get too
much volume from a low-powered amplifier
than from a high-powered one.
