Description

Infinity subwoofers have always distinguished themselves clearly from the competition. The Infinity SSI Kappa series subwoofers are no exception and fight on a playing field all their own. Right away the coated glass-fiber cone shows off an air of sophistication and style while offering incredible rigidity that minimizes distortion.

Once you get past the cultured exterior, the interior components uphold Infinities affinity for advanced technology. This Kappa sub utilizes a triple voice coil system which gives it the incredible ability to offer selectable impedance. Selectable Smart Impedance (SSI) technology allows this sub to run at 2 Ohms or 4 Ohms with the flick of a switch. This allows you to extract the most from your subwoofer amplifier in any situation. If you decide to add a subwoofer down the line, SSI makes it easy to reconfigure your entire system without buying different subwoofers or amplifiers.

The SSI Kappa subwoofers handle a remarkable amount of power and sound incredible in sealed or ported enclosures. If you want great sounding bass with unheard of wiring versatility, Infinity Kappa subs are technologically advanced enough to handle it.

GREAT sound

I have many years of experience in studio recording in the music industry - as a musician. So I was looking to build a system that can replicate the studio sound as best as I could to listen to a wide variety of music. I do not need thumping deep rattle the next car bass, I want clean musical sound. I have had alpine subs and those can punch and get some solid deep bass, but that was not my goal with this setup (although it can do that too, rather well). This is my 2nd purchase of this sub in a second vehicle and in both cases this has performed exactly what I needed. The sound of an upright bass sounds amazing, can easily go into the higher frequency range and make the transition from door speakers to sub seamless. I bought this sub to play anything I threw at it and do it well, not to only play one type of music all the time. Mostly Jazz, Classic Rock, Ska, 90's, Classical, Pop (wife likes that stuff..) and occasional R&B. I recommend the kappa components to go along with the sub - some say the highs are harsh, but I call it accurate and clear. This sub can do it all, I'm very happy with it.

TL;DR, get this amazing sounding sub for your setup if you want perfect sound and a strong presence. Might want to go larger than 10" or another brand if you want that deep killer decibel punch and trunk rattling bass;)

Awesome sub for the price

It hits hard and looks great. The 4 to 2 ohm switch makes setting up your amp easy. I'm running it with a mono block jl 500 watt amp and outs loud and hitting great.

car speakers

These speakers sound nice and balanced not to boomy but a good punchy bass and treble sound. They can handle whatever power amplification is fed to them. I would recommend them for their overall value and just crisp clear sound without the distortion.

Great sub!

For a single 10", this sub hits hard. It looks even better. Hookup is flexible with the 2ohm switch. Makes wiring that much easier. Just what I needed to add clear bass to my system without annoying everyone else around me.

high quality

have lots of experience in the car audio industry and decided to get these after doing research on what i felt would be best for my setup. My last system had 2 L7 12s but this time i was looking to conserve a little more trunk space and was looking for more quality. put this in the recommended .75 sealed enclosure powered by a polk 5 channel amp and have been impressed so far. doesn't hit the lows like my last setup but for the size this really packs a punch. One of the most accurate sounding subs ive heard. going to try it in a ported box soon to compare.

High Quality Sound

I ordered two of these and built a box to Infiinty's specs with 1" MDF. These sound so great! They don't play extremely loud (powered perfectly by a Kappa One) but they blend so well with the rest of the system. The sound is clean and hard, not boomy. On that note they can handle high volume, but if you want that slammin' bass in your face feel, these aren't for you (I know these are only 10's. but I'm confident the 12's are very similar). I am an Infinity loyalist in the car as well as home, and these remind me why!
