Verdict
The Infinity brand division of Harman International has shifted its focus away from home audio-oriented speakers as of late to solely concentrate on its mobile sound products, a decision that has yielded such honorary mentions as the Kappa 1000W 10-inch free air subwoofer.
With their rugged construction and sophisticated engineering, Infinity’s Kappa subwoofers excel in a variety of environments, from casual to competition, and the 1000W reflects this ability with its selectable two- or four-ohm impedance.
Pros
- Durability and sound quality excellent for the price
- Low-end response punches beyond its class
- Balanced output characteristics without much muddiness
Cons
- Not in same league as some other subs in its price range that can handle more than 600 watts RMS
- Not the loudest sub you’ll ever hear
Review
In putting the 1000W through its paces, we found this 10-inch bass maker to perform somewhat above its class, and while it isn’t the loudest sub you’ll ever come across, it boasts all the hallmarks that make a great woofer: Coated glass-fiber cone with rubber surround, steel basket, impressive frequency response numbers and power rating values of 450 watts RMS/1,800 watts peak.
What’s more, like Infinity’s once-coveted home speakers, the 1000W comes fully loaded with a 90dB sensitivity – which means this sub doesn’t need groundbreaking amounts of current to get thumping. Hard-hitting and accurate when considering its price point, the Infinity Kappa 1000W isn’t all about mind-numbing slam; even one of these in a proper enclosure can sound very musical and involving in ways many others in its class don’t.
As one of the primary selling points of the 1000W, the unique Selectable Smart Impedance lets you build the exact system of your specific dreams, whether it be a high-powered or multi-sub arrangement, devoid of all the complicated wiring. Just flip the convenient impedance switch to safely select between two or four ohms, and you’ll be off to audio nirvana in no time.
Further, Infinity’s proprietary aero-cooling design keeps the voice coil at normal operating temperatures, even when the subs are being driven hard, while optimizing power handling and long-term reliability. The acoustically-damped glass-fiber cones, meanwhile, have been engineered to minimize distortion and reduce frequency-robbing artifacts in an effort to deliver nothing but clean bass output.
