Focal's 3-way Polyglass VR3 component speaker system uses precision craftmanship and advanced materials to make a strong sonic impression. The system includes two 6-3/4" woofers, two 4" midrange drivers, two tweeters, two external crossovers, and assorted hardware.

2-layer woofer cone
The 165 VR3 system features a 6-3/4" woofer with a Polyglass cone that's created by depositing a layer of hollow glass microbeads over a layer of cellulose pulp. This unique material combines the warm sound of cellulose with the incredible strength of glass, for a cone that responds rapidly with extremely low resonance. A butyl rubber surround helps control cone movement and promotes high power handling. The zamak (zinc alloy) basket provides a non-magnetic, non-resonant housing that won't color the sound.

Unique tweeter design
Focal designed the aluminum/magnesium inverted dome tweeter to disperse high frequencies evenly for a big, open soundstage. The external 2-way crossover ensures a smooth transition from lows to highs, so vocals and instruments sound natural. You can select from 3 tweeter levels to get the right balance in your vehicle.

4" midrange speaker
The shallow-mount 4" midrange driver, identical in construction to the woofer, adds focus and detail. Mount the midrange and tweeter as close to ear level as possible in your vehicle, and enjoy the powerful soundstage created by these precision speakers.

Note: This component speaker set consists of a separate woofer, midrange speaker, and tweeter. Our Car Selector checks to make sure the woofer will fit in your factory location. You'll have to custom install the midrange and tweeter.

Note: Focal describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Woofer

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 to add to the speaker's reliability and longevity.

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.

Midrange

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 basket.

Neodymium Magnets: The midrange drivers use Neodymium magnets, which have the same magnetic flux power as a ceramic magnet 10 times their size, reducing the size and weight of the speaker.

Size: The 4" midrange drivers will fit most factory 4" speaker locations. They can be top or bottom mounted and have these dimensions:

  • Depth (top mount): 1.57"
  • Mounting height: 0.33"
  • Flange height: 0.19"
  • Depth (bottom mount): 1.76"
  • Tweeter protrusion: 0.14"
  • Cutout diameter: 3.672"
  • Frame diameter: 4.022"

Tweeter

Inverted Dome Tweeter: The tweeter is an inverted aluminum/magnesium 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. Focal recommends flush mounting, but the included angled cup allows surface mounting at one of two angles; approximately 10° and approximately 30°.

Crossover

Components: Focal uses audiophile grade polypropylene capacitors and solid core inductors to ensure high definition and a dynamic sound quality.

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 4,000 Hz.

Wiring: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.3" wide.

Tweeters:

  Flush Mount Angled Surface Mount
Mounting Height 0.274" 1.186"
Depth 0.688" (1.01" including screw) 0.527" (screw depth)

Hands Down, Focals are the best!!

Written By 2fast4thelaw, Denver, CO on Wednesday, September 02, 2009

These speakers are absolutely amazing. I have owned several sets of Focal speakers and that is all I will buy. They are loud and clear with detail you never knew existed! The midbass is very strong! Those little 4" mids really crank!

I have these installed in my 2006 Nissan Armada. The midbass are installed in the factory location in the doors, the mids are mounted up high in the door and the tweeters are in the stock tweeter location in the dash. The imaging is incredible and they fill that huge cabin with sound.

I am running 75Watts RMS from my Alpine amp and its plenty of power. I can't handle them full blast for more than a minute or two and I like my music LOUD!

If your looking for 3-ways, these are it!! Just buy them and forget what they cost. They are worth every penny! Best sounding speakers I have ever owned and I have a couple of sets of the higher end Ply Kevlar K2P Focals but they are 2-ways. If you can possibly fit 3-ways, they are the way to go!
