KAPPA 120.9W

This cone material is extremely stiff, minimizing cone flex; its rigidity results in the very low distortion and improved clarity that are Infinity trademarks.

Reduces air compression under the dust cap, minimizing mechanical noise, and provides more constant mechanical Q for reduced distortion.

Provides great performance in sealed, vented or band-pass enclosures. Kappa woofers can be ±30 percent of the recommended volume. Optimum vented boxes do not require superlong ports.

Infinity subwoofers are tested according to the strictest and most demanding reliability-testing regimen ever designed for car-audio speakers. They are shaken, baked, frozen and dropped, all while they’re operating, and attempts are even made to destroy them with signals up to 10 times their rated power. When they’ve passed those tests, the subs are subjected to their RMS and peak power limits for 100 hours. Many competing subs are tested for only eight hours.
