40kHz High-resolution Silk Dome Tweeter

Dreaming of audiophile-grade speakers to install in your vehicles is now not an impossible thing to think about, thanks to Infinity. The brand has a reputation for manufacturing high-quality audio components, and now its Kappa is purposely designed and made only to suit every audiophile's taste, and the Infinity Kappa 53XF is the perfect testament to that.

 

Patented Plus One™ Glass Fiber Woofers

The Infinity Kappa 53XF is a 5.25-inch 2-way car speaker that comes with Infinity's Plus One woofer made of glass fiber and with a hi-roll rubber sound, giving it the needed stability to produce an accurate mid and low-frequency response without distorting. The woofer has more surface area than other speakers, allowing for more bass sound that perfectly pairs up with its tweeters.

0dB or -3dB Tweeter Output Level Control

The Infinity Kappa 53XF's tweeter is made of silk with an edge-driven dome design, giving it a bright, crystal-clear high-frequency performance with lesser distortion. You can also adjust the positioning of the tweeter, so you can point it toward your ears for a better listening experience. It also has a level control button for adjusting the tweeter's brightness.

UniPivot and Angled Tweeter

The Infinity Kappa 53XF can handle a power output of 60 Watts RMS and reach up to 180 Watts of peak power at a 3-ohm impedance. It also has a frequency response of 55 Hz up to 40 kHz, which is impressive for a full-range speaker of this size, and it has a sensitivity rate of 93 dB, allowing it to go at high volume levels with minimal distortion only.

  • Diameter : 5.25 Inch
  • Sensitivity : 93 dB
  • Impedance : 3 Ohm
  • Frequency Response : 55-40000 Hz
  • Peak Power Handling : 180 Watts
  • Design : 2 Way
  • RMS Power Handling : 60 Watts

Features:

  • Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
  • Edge Driven Dome Tweeters: Each speaker has an edge-driven silk dome tweeter. Edge-driven tweeters have better dispersion characteristics and allow for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity. The tweeter also has an output level switch; choose +0 dB (flat) or -3 dB.
  • UniPivot Tweeter: The tweeter is angled and can be rotated about 315° after installation. This allows you to direct the tweeters toward the listeners, very useful for speakers mounted low in a door.
  • High-Output Design: The high output 3? voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4? speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 3 load.
  • Terminals: The input terminals are set screws that will accept up to 12 gauge bare wire.

  • To be quite honest, Im not impressed with this speaker, at least not so far. My biggest issue is the design does not fit a 5.25 door panel in all most all Toyota's without modification. They also in my opinion , sound a little too bright so u absolutely have to have a subwoofer in the mix or you will experience some ear fatigue. Im a infinity fan - i have some 69IX 6x9s in the back of my car but these 5,25 kappa have not combined well with them at all so i think i will go back to my old focals in the front. Its possble my 5.25 kappas are a chinese version which means absolute lack of quality. The ones I bought we're off a site on Amazon and there was no answers no mention of where they came from China or US if you buy the speakers make sure they're American made if you don't you will regret it. Chinese electronics are garbage imagine that....

  • Fits perfectly in my Lexus. The sound quality is amazing—such a night and day difference compared to the old stock speakers. Bass might not be what I imagined but still happy with its full range performance.

  • Tight bass for the size. Try them out with two nice full-range amps and they sounded really great. you should really prioritize to have a powerful in pushing these speakers, so you can also get the best results out of them.
