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.

I got two of the kappa 100.9 in my Infiniti G37 and it rocks really hard. They are powered by an infinity kappa one which really delivered an awesome sound. I also have a kappa four for my kappas 6x9 and 6-1/2" components which is really awesome. Would recommend any time.

Very nice quality subwoofer, at an affordable price. Build quality better than Kicker yes. I have always used Kicker subwoofers, and this time I just wanted one small 10" driver. I chose to give this Infinity Kappa 10" a shot. Just got it hooked up today, and I was blown away with it's sound reproduction and output for such a small driver. I have it in a 1.0cu ft sealed enclosure. Hits accurate, deep and tight. I have about 600rms going to it. You wont find a better sub for the price period.
