The BTR Enclosures are designed to provide superior sonic performance from
a pre-fabricated enclosure. These enclosures, designed and tested at Rockford
Fosgate, can satisfy even the real “head banger” with their output capabilities
while still providing the sound quality many have come to expect from
Rockford Fosgate.
BTR Design Goals
Woofer Features
Black Anodized Aluminum Voice Coil Former
Because aluminum is an efficient thermal conductor, the black, anodized
aluminum voice coil former keeps heat from concentrating in the voice
coil during normal operation. This improves the thermal power handling
capacity of the “Box That Rocks” speaker.
Vented Pole Piece
To allow operation at reasonably high power levels, ventilation is needed.
This is done through the use of a vented pole piece. The venting allows
fresh air to circulate and remove the built-up heat from the voice coil
assembly.
PVA Treated Paper Cone
The cone is constructed from a lightweight, rigid paper material. The cone
is treated with PolyVinyl Acetate which lowers the resonance and reduces
distortion of the cone. The PVA also reduces damage from the harsh
environmental conditions typical of a car interior.
