INTRODUCTION
OPERATING / FEATURES
Amajordesignchallengewhenbuildingaventedspeakerenclosureisthe
turbulence generated by the air moving through the port. The air move-
mentcausesharmonicdistortionaswellasawhistlingnoisefromtheport.
The Aeroport was designed to reduce this effect. Inspired by the bell on a
brass instrument, the flanges on the ends of the Aeroport reduce the air
friction and distortion inherent in the operation of a conventional tube.
This manual provides information on the features, installation and
operation of the Aeroport. We recommend you keep this manual for
future reference.
We strongly recommend you have your Authorized Rockford Fosgate
Dealer install your new Aeroport; however, if you choose to do the
installation yourself, please be sure to read the entire manual before
beginning. When installing this product, please use the proper safety
precautions while using power tools or flammable materials.

tube can reach that amount with only 10 watts of input where as the
Aeroport reaches only .05% distortion with 50 Watts of input. The end
result? You can apply more input power with less distortion or use a
smaller diameter Aeroport in place of a standard tube.

CALCULATING PORT LENGTH
After the enclosure has been designed, the following formula may be
useful when calculating the port length:
Lv =
Lv = port length in inches
Vb = volume of box in cubic feet
Fb = tuning frequency
R = radius of port

When cutting the Aeroport center tube, the length should be cut 3"
shorter than calculated. When the end flanges are affixed, each end

then the fully assembled Aeroport (center tube with flanges attached)
shouldmeasure 11" (theextra 1/2" on each endcontributes to harmonics
