SUB 25

December 9, 2008 - Paradigm Electronics Inc. announces shipping of its most powerful and intelligent subwoofer ever: the Signature SUB 25. Recognizing that on-demand power is the essence of subwoofer performance, Paradigm has designed the SUB 25 to effectively harness and optimize AC line current for optimal performance.

All AC line voltages are not created equal, and some A/V equipment has more robust power demands than others. Paradigm has equipped the SUB 25 with universal input power, which allows the subwoofer to operate intuitively on a 120 V or 230 V circuit. This is possible because the SUB 25 can handle the load from any line voltage between 108 V and 265 V.

This flexibility to accept a range of line voltages is welcome, but how this power is managed is even more critical. The SUB 25’s Power Factor Correction technology shapes the AC line input current to be sinusoidal and continuous in time. A unit without Power Factor Correction can only draw about 60 to 70 percent of the maximum available power because the current only flows at the peaks of the line voltage, essentially “choking” the line. The use of Power Factor Correction allows the SUB 25 to accept the maximum possible amount of input power, while its high-efficiency Ultra-Class D amplifier, rated at 7,500 watts Dynamic Peak and 3,000 watts sustained RMS, allows the maximum amount of output power. By combining both, the SUB 25 delivers the most power that can be obtained from the AC line. Read more
