Polyglass Cone: The woofer cone has a cellulose pulp base
and is coated with a uniform deposit of hollow glass microballs. The addition of
the Polyglass layer significantly increases the cone's rigidity without adding
much weight. This combination takes advantage of the accuracy and neutrality of
the hard outer surface, but maintains the superior damping characteristics of
the cellulose pulp.
Surround: The butyl rubber surround is resistant to ultraviolet
rays, temperature extremes, and humidity, adding to the speaker's reliability and
Zamak Basket: The woofer features a cast Zamak basket. Zamak
is a rigid alloy of Zinc, Aluminum, Magnesium, and Copper. Zamak is non-magnetic.
Voice Coil: The voice coil is wound around a 1" diameter
low-mass Kapton former, ensuring no coil deformation.
Polyglass Cone: Like the woofers, the midrange drivers use
Polyglass cones with butyl rubber surrounds.
Zamak Basket: The midrange drivers also feature a cast Zamak
Size: The 4" midrange drivers will fit many factory 4"
speaker locations. They can be top or bottom mounted and have these dimensions:
- Depth (top mount): 1.572"
- Mounting height: 0.273"
- Flange height: 0.181"
- Depth (bottom mount): 1.753
- Tweeter protrusion: 0.092"
- Cutout diameter: 3.682"
- Frame diameter: 4.02"
Inverted Dome Tweeter: The 1-3/4" tweeter is an inverted
aluminum dome, producing a broad sound stage. The tweeter has a Neodymium magnet
to provide a powerful magnetic field for the voice coil, while still maintaining
the tweeter's compact dimensions.
Mounting Options: The tweeter can be surface or flush mounted
using the included adapters. The included angled cup allows surface mounting at one
of two angles; approximately 10° and approximately 30°.
| ||Flush Mount ||10° Surface Mount ||30° Surface Mount |
|Mounting Height ||0.274" ||1.212" ||1.553" |
|Depth ||0.962" ||0.552" (screw depth) ||0.552" (screw depth) |

|Frame Length ||N/A ||1.842" ||1.776" |
Components: Focal uses audiophile grade polypropylene
capacitors and solid core inductors to ensure high definition and a dynamic
Tweeter Level: You can adjust the output level of the tweeter
on the crossover to -6 dB, -3 dB, or 0 dB.
Crossover Slopes: The crossover uses 2nd order (12 dB/octave)
low-pass, band-pass, and high-pass filters. The crossover points are 400 Hz and
Wiring: The inputs and outputs are screw terminals; they will
accept bare wire or spade connectors up to 0.3" wide.
- Width: 3.335"
- Height: 1.577"
- Depth: 5.088"
