You’ll get a fantastic stereo sound even when the speakers are positioned on the floor or in low places in your doors. Each tweeter comes with a control knob to adjust the level, so you can control the brightness to suit your needs.

Plus One+ technology for woofers

The Kappa’s fiberglass woofer can hold its shape even when you crank it up and still deliver the crisp, powerful bass. Fiberglass is lighter than other materials, which means you don’t require a huge amount of power to run this woofer.

With Infinity’s Plus One+ woofer technology extends the cone’s reach to the edges of the basket, providing the user plenty of surface and a bigger cone provides more bass to compliment the exceptional high-frequency response.

Amazing power handling, regardless of the configuration

The 3-ohm speakers have extremely high sensitivity. You can run them through an original radio or an aftermarket stereo. However, you’ll have the best performance by putting them through lots of power via the external amplifier.

In any case this speaker’s low impedance makes use of every Watt of power to provide exceptional performance. You can enjoy Kappa high-quality sound in any setting.
