Larger tweeter in a 3-way system

Handmade in France, the Elite K2 Power Series 165KX3 component system is the culmination of Focal's passion for perfect sound, exceptional standards, and technological advances. Focal's sound gurus engaged in intensive listening sessions designing this line of speakers so that you hear uncanny realism, sweeping dynamics, and breathtaking depth in your music.

A classic woofer with a new twist

The 6-1/2" woofer uses Focal's classic "W" sandwich cone design to reproduce your audio with incredible accuracy. The nimble Kevlar and glass-fiber woofers demonstrate the control needed to play delicate classical passages, yet they'll handle the power needed to drive your bass-heavy tracks with authority. Focal adds a new Tuned Mass Damper (TMD®) rubber surround which minimizes harmonic distortion for the cleanest midrange possible. The 3" driver in this 3-way system uses the same sandwich cone to deliver all the midrange details.

A redesigned tweeter

The ES 165KX3 employs a unique 1-1/8" aramid fiber tweeter with an "M"-shaped inverted dome design that disperses the highs with remarkable precision, all the way up to 22,000 Hz. The K2 Power crossovers use hand-made components developed by Focal to deliver an ideal blend of the highs and lows for a dynamic stereo image. Three levels of tweeter control let you dial in the sound to your car's environment.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

A dynamic and fluid 3 way component set!

Tony from San Diego, CA on 11/13/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

These are installed in a Hyundai Accent, circa 2013 by a shop in La Mesa. I have a DEXP99RS CD Tuner by Pioneer and a V9 power amplifier by Alpine running them in a bi amplified configuration. Vocals by Taylor Swift, Janet Jackson sound breathtaking. I find myself taking so many unnecessary trips. Even the song When Doves Cry, Prince does this cool thing with the squak box intro where the sound shifts within a brief space after the blistering guitar intro. Breaking in speakers still 40+ hours and they sound more amazing.

Pros: Life like and sonically accurate! Can handle a lot of power.

Cons: Find a good installer with skills and patience.

Woofer

K2 Cone: The woofer cone is a sandwich composite consisting of a foam core, a structural glass fiber bottom layer, and a Kevlar top layer. This combination of materials results in a rigid, light weight cone with excellent damping characteristics.

Surround: Focal's patented butyl rubber TMD (Tuned Mass Damper) surround helps control unwanted resonances, providing a clean and neutral midrange with very low harmonic distortion.

Voice Coil: The voice coil is wound around a 1-9/16" diameter low-mass Kapton former, ensuring no coil deformation.

Size Classification Note: Some manufacturers, including Focal, call this size woofer a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size as a 6-3/4". Please enter you vehicle information to confirm fit in your vehicle.

Midrange

K2 Cone: The woofer cone is a sandwich composite consisting of a foam core, a structural glass fiber bottom layer, and a Kevlar top layer. This combination of materials results in a rigid, light weight cone with excellent damping characteristics.

Phase Plug: The bullet-shaped phase plug in the center of the midrange ensures a smooth, flat off-axis frequency response by preventing the high frequency sound waves emanating from one side of the cone from interfering with sound waves from the other side of the cone.

Size: The midrange drivers are not a standard size, approximately 3" diameter. They can be top or bottom mounted and have these dimensions:

  • Depth (top mount): 1.314"
  • Mounting height: 0.272"
  • Flange height: 0.165"
  • Depth (bottom mount): 1.479"
  • Tweeter protrusion: 0.107"
  • Cutout diameter: 2.885"
  • Frame diameter: 3.452"
  • Grille diameter: 3.847"
  • Grille height: 0.595"

Tweeter

Inverted Dome: The "M" profile, Aramid fiber, inverted dome tweeter is designed to increase precision at very high frequencies. The push-pull motor also damps acoustic resonances on the back of the membrane and extends the low end of the frequency response.

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 60° and approximately 40°.

Tweeter/Midrange Mounting: Two surface mounting pods are included that hold a midrange and tweeter. The pods' dimensions are 6-7/8" x 4-1/4" x 3-1/8" (height above mounting surface).

Crossover

Components: Focal uses audiophile grade polypropylene capacitors and air core inductors to ensure high definition and a dynamic sound quality. Thermal camera imaging is used to optimize component power dissipation, improve reliability, and lower temperature.

Bi-amp Inputs: Each crossover has bi-amp inputs, one input for the midrange/tweeter combination and one for the woofer. When using only two amplifier channels the crossover inputs must be shorted together using two short pieces of speaker wire. Focal recommends using four amplifier channels to bi-amp the speakers for the improved dynamic range and to present an easier load for the amp(s) to drive.

Wiring: The inputs and outputs are set screw terminals; they will accept bare wire up to 10 gauge.

Slope: The midrange (band-pass) and tweeter (high-pass) crossover slopes are 12 dB/octave. The woofers' low-pass slope is selectable between 12 dB/octave and 6 dB/octave.

Crossover Points: There are three crossover frequency options between the woofer (low-pass) and midrange (high-pass), 300 Hz, 400 Hz, and 500 Hz. The crossover point between the midrange and tweeter is fixed at 3.5 kHz.

Adjustments: Five switches allow customizing the crossover output:

  • Tweeter Level: three position switch; -3 dB, 0 dB, or +3 dB
  • Tweeter Shelf: on/off switch; high-frequency boost emphasizes extreme (high) treble frequencies, designed to improve definition
  • Midrange Level: three position switch; -3 dB, 0 dB, or +3 dB
  • Midrange Frequency: midrange high-pass crossover point; 300 Hz, 400 Hz, or 500 Hz
  • Woofer Slope: low-pass crossover slope; 12 dB/octave or 6 dB/octave

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
Have K2's now and are very impressed, needed to go to 3-ways. [ Morey Rozon -  Aug 29, 2017 ]

2 questions already asked

Q
Do you know what the RMS rating for EACH speaker is? On the Focal website they only list max power and nominal power. I'm assuming the nominal power is supposed to be the RMS? however the values for the mid range driver and especially the tweeter seem low. 50W and 20W respectively. I want a high end set of components to match with a JL 12w7AE (1000W RMS). If these Focal ratings are correct it would be a combined wattage of 380W RMS compared to 1000W RMS for the sub, which would result in a really unbalanced system.
[ New User  Apr 18, 2018 ]

A
Nominal power is another way of saying RMS power. It still refers to the ideal watts that they can handle. Another thing to note is that it takes a lot more power to produce a bass frequency than it does to produce a midrange or high range (treble) frequency. So the watts for the bass will always be higher than the watts for the midrange drivers. And the midrange's watts will always be greater than the watts a tweeter needs. I've always used a general rule where you send a subwoofer 4-8 times the power you send the other speakers when I've been making sure the bass is neither too weak or to strong. This match is close enough that I know I've built systems using it. I think its a good match! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101

Q
Do the Focal ES 165KX3 and Focal Utopia Be No.7 drop to 1 ohm like the Focal K2 Power 165 KRX3? I know some amplifiers have a hard time driving that load and have to be bi-amped.
[ Ryan Box  Jun 28, 2017 ]
1 answer
A
Technically, any speaker can drop to a 1 ohm load when its producing the deepest bass notes. However, that is not a sustained ohm load and is a built-in aspect of speakers and amps. And also why RMS power and nominal ohms are used to match speakers to amps. Think of them like the normal running watts and ohms so on average, that's what the amp sees and what we match to.
