Our take on the Focal Polyglass 165 V30

by Buck Pomerantz

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.

Focal's Polyglass V30 component speaker systems use precision craftmanship and advanced materials to make a strong sonic impression. Each system includes two tweeters, two woofers, two crossover networks, grilles, and assorted hardware. Power this system with a quality amplifier, and you'll be knocked out by the precise, natural sound of these Focal speakers.

2-layer woofer cone
The 165 V30 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 2 tweeter levels to get the right balance in your vehicle. Woofer grilles are included.

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.



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.

Voice Coil: The 1" diameter voice coil is wound around a low-mass Kapton former, ensuring no coil deformation.


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°.


Components: Focal uses audiophile grade polypropylene capacitors and air 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 0 dB or -3 dB.

Crossover Slope: The crossover points and slopes are switchable; choose 6 dB/octave low-pass and 12 dB/octave high-pass at 3,700 Hz or 12 dB/octave low-pass and 18 dB/octave high-pass at 5,000 Hz.

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

Midgrade materials + premium craftsmanship = great value!

Written By hayasa8, Atlanta, GA on Wednesday, November 28, 2012
Really pleased with the sound of these in our 2000 VW Golf. They need more power than a head unit can give them to really shine, but are actually pretty efficient and would likely exceed most folks expectations on a 22-watt RMS Head Unit (specified b/c that's what my unit is rated). Feature a very nice but neutral sound but appropriate mid-bass snap. If your head unit allows you to high pass the channels these are on- set it at 40-60Hz and you can save yourself some power and keep these things well fed on the H/U The tweeters are excellent- among the best I've ever heard. The crossover has versatile settings and is small enough to not be cumbersome to install. Great value, very precise speaker that is accurate and never taints the music with its own personality. Just accurate and nice over a divers spectrum of music styles. I'm an audiophile- have been for years. I have Diamond Audio Hex and the old M5 gear in my 350z with old Steve Mantz amps, Dynaudio 362 with a Diamond Audio MacDaddy 12 in RX8 with McIntosh amps fed by a quad burr brown DAC based processor (optical connections from all until we get to the amps), & have put together systems for all my friends and family (of all budgets) for years. In comparison to the vehicles referenced above I'd put the Focals right ahead of the Diamond Audio gear because the tweeter is much nicer and smoother for longer periods - less listening fatigue. My only beef is that woofer isn't quite as ?hardy? as I'd like to see.
Sounds better than most things twice its price. Efficient. Can play anything well. Very smooth tweeter, not harsh no matter what I throw at them, from Foo Fighters (IMHO very busy tracks that kind of turn to harshness with most systems) to Stevie Wonder & even Adele. Just right, never irritating. Phase plug seems to actually help keep soundstage elevated and keeps sounds like the meat of snare pop from getting lost. Woofer excels at transitions that leave other drivers sounding like mud.
The woofer basket is plastic and pretty flex-y, so I wonder how well these will age in the heat of a car. Also, make sure you keep them very flat when mounting- spec is so tight that the easily warping basket could cause premature failure if not flat/level and secure. Really needs a small amp to shine, but best quality and efficiency you'll find if you're limited to H/U power. Tweeter surface mounts aren't very good, while the flush mount seems nice.

Focal Polyglass 165 V30

Written By Marty, Hervey Bay on Wednesday, February 08, 2012
Generally nice sounding, however the treble is a bit harsh, overpowering and fatiguing. However this may be because of other factors such as the position of my tweeters (head height on door frame) or head unit (pioneer). Also worth mentioning that my pair are not brand new and have had a well used life.

Crutchfield Customer Review (What's this?)
Installed them in my 2011 Chevy Tahoe and man what difference in sound from the factory speakers. I was going to go with a set of JL Audio speakers but after reviewing both products and with the Focal on sell i jumped at the chance and purchased the Focals. No disapointments here.
GREAT SOUND with an amp.

These are some sweet sounding speakers powered with alpine pdx f4 amp with all doors completely deadened with dynamat. I have no sub but midbass is amazing and smooth. Tweeters are good. Not harsh. No complaints except for the fact that they re expensive. Hands down most expensive set I ever bought. No regrets. Well built, seems like it will last awhile.
Sounds awesome.
Oversized 6 1/2 so had to fabricate custom brackets to install.

love for sound

Written By offerald, raleigh, nc on Tuesday, March 29, 2011
i have heard every expensive component set there is ucrrently in the industry. these components are better than the standard polyglass. mid bass is incredibleand has a live sound a feel. I am currently using krx3's is current car car and these in my 96 accord. This is the best component for the price money can buy. i choose these over JL c5 Alpine X-type polk SR and a few others. Need at least 100 watts and sound best on a/b power supplies.

Focal Polyglass 165 V30

Written By Cory, Ventura, CA on Sunday, August 29, 2010
This component set is amazing. Natural sounding tweeter and great midbass. Orginally had other components installed but the tweeter was too harsh. Focal was a little more expensive but worth the price. Paired with an JL Audio HD600/4 or even Alpine PDX 4.100 these work well. Filled the rear with a high-end series and the truck sound quality and level is awesome.
