Enclosure Features
• Input Terminal Cup – The input terminal cup provides
quick and easy connection of the enclosure to the ampli-
fier.
• Precisely Tuned – The enclosures utilize a specialized
tuning port to increase it's output effeciency. For maxi-
mum performance it is important not to block the airflow
from the port as it will degrade sound quality.
• Plexiglass Window – The see-through plexiglass window
lets you see how hard Punch Woofers can hammer!
Silkscreened with the famous Rockford logo you can
show your friends that your ride has the best woofers in
the world.

Speaker Features
• Woofer – The woofer supplied with the RBP enclosures
is a genuine Punch HE woofer designed to withstand
high power levels. A Black Anodized Aluminum Voice
Coil Former dissipates heat away from the voice coil and
a Vented Pole Piece allows fresh air to circulate around
the voice coil assembly. These features dissipate generat-
ed heat very efficiently and allow the woofer to with-
stand higher thermal power handling.
