Features

  • Infinitys glass fiber woofer cones are lighter and stiffer with more cone-area than the competition , delivering increased low-frequency output and higher efficiency.
  • Edge-driven textile dome tweeters - These are not commonly used W-domes, but edge-driven textile dome speakers that will deliver broader and smoother high frequency response.
  • High output 2.5 ohm ohm architecture with low impedance voice coils enables the speaker to extract every watt from the amplifier and deliver peak power with ease.
  • Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
  • Infinity is in the business of designing reference quality speakers, and Kappa car audio speakers are no exception.

Our Patented Plus One woofers deliver tight robust bass and high-output that is detailed and musical. Edge-driven textile dome tweeters with oversized voice coils deliver silky smooth highs with increased thermal power handling for high volume enthusiasts. Every model is voiced using audiophile grade inductors and capacitors resulting in detail and accuracy unmatched by other brands in their class. And Kappa's 2 ohm design extracts every watt of power from the amplifier or head unit for exceptional performance. In The Box: 2 x Speakers 2 x Spacers 2 x Foam gaskets 8 x screws 8 x speed clips 2 x Infinity logo badges 2 x brand stickers Owner’s manual Power Handling - 60W RMS, 180W peak Sensitivity (@ 2.83V) - 94dB Frequency Response - 75Hz – 25kHz Voice Coil Diameter - 1 in. (25mm) Impedance - 2.5 ohms High sensitivity allows high-output without overdriving the system. With a sensitivity of up to 96 decibels at 2.83 volts/1 meter, Kappa speakers achieve excellent volume with superb musicality with as little as 5 watts RMS. (Kappa speakers are ideal for upgrading original factory-installed speakers.) Speakers are individually tuned with outboard passive crossovers using audiophile grade inductors and capacitors to assure high quality audio versus “off-the-shelf” sound. This means that specifications as well as speaker characteristics are considered when tuning the Infinity sound.

  • Great speakers, some of the mounting holes were cracked but didn't affect installation.
Beautiful sound. I will say that both pairs of speakers had tabs that were broken but it didn't affect mounting. I paired this set with the Taramps TS 800x4. It's nearly perfect. These are rated at 100W RMS and the Taramps TS 800x4 is rated at 156W RMS with 14.4v input voltage. I figure I'm running under 14v so likely putting a little over 120W RMS into these and they're perfect. ... show more

  • Great sound quality, solidly built, awesome speakers.
Superb sound quality - fit great in my 2010 F150. The only downside is having to buy the factory speaker adapter - it wasn’t available for my truck on Amazon and I had to wait a few extra days. However, once those arrived it was a simple plug and play install. The sound of these speakers is incredibly crisp and clear, really good low end bass (picking up frequencies that my factory speakers wouldn’t even attempt), no distortion even at higher volumes. Build quality seems excellent. I like the adjustable directional tweeters, they also have a toggle on them to boost the db output. Overall I’m super happy with them. High end sound quality, pretty good price. I’d definitely recommend them! ... show more

  • Incredible sound
When using with the right amplifier, these speakers sound absolutely amazing. Super loud, incredible bass and crystal clear when turned up all the way. Easy to install and seem to be built very well. For the price you can’t beat it

  • Great speakers
The speakers themselves are great, unfortunately my first order of 2 sets showed up with the cheapest 6x8 speakers sold by Skar in the box. Don't order from Amazon Warehouse Deals, I figured I'd save a few bucks but the person who accepted somebody's return is incompetent, that set my install back a couple weeks. My new set is ordered and on the way. I've installed lots of these, these and Kicker CS 6x8's are some of my favorites to put in the Ford trucks these fit in. ... show more

  • Great volume, great sound, and great mod base.
Amazing sound! Specially the mid-range base. Definition at low volume y not great, but it brightens up from mid to high. I pair this with (Amazon basics) sound deadening on the inside of my doors and around the speaker mounting area.

  • Gran calidad de sonidos reproduce bien todas las frecuencias y con buena potencia
Ya habia tenido infinity antes y se que su calidad es muy buena , gran claridad, buenos agudos , pero las consideraba bocinas que no podias darle mucho volumen por que sufrian. No es el caso con estas bocinas tienen exelente calidad y ademas buena potencia. me gustaria escuchar las 6x9 deben ser exelentes. De hecho compre un bajo de la misma linea de lo que me gustaron la bocinas ... show more

  • Contacts broke while inside the door.
One of the speakers stopped working so i removed the door panel and the speaker and found the speaker contact had broken due to bad solder. Seller didn't help after i contacted them.
