Infinity Kappa Amplifiers

Infinity Systems, a Harman International company, announced its innovative new line of Kappa One, Kappa Four and Kappa Five amplifiers. The new Kappa amplifiers utilize Infinity expertise in full-range Class D amplifier technology. The Kappa One and Kappa Five apply Dynamic Bass Optimization (DBO) – a proprietary variable subsonic filter with variable bass boost. DBO conserves power at frequencies below 100Hz, protecting woofers in vented-box applications from over excursion, and flattening response through the lowest octaves in sealed-box and infinite-baffle applications, according to Infinity. All three amps feature a one-year warranty and range in price from $549.95 to $599.95. These amps are shipping in April 2009. For more information, Infinity’s Kappa Web page.
