SpeakerPower has introduced the SP1-4000 Torpedo, a plate power amplifier for loudspeakers and subwoofers rated at 4000 watts into 2 ohms from a package weighing in at just 7 pounds.
The SP1-4000 Torpedo utilizes the latest generation power MOSFET transistors and a highly optimized output stage for over 90 percent efficiency, providing quiet fan-less operation up to extremely high power levels.
A single unit has the ability to drive up to four woofers to their limits while staying cool and maximizing the AC power available.
Innovative post-filter feedback class-D topology helps to deliver ruler-flat frequency response, low distortion and very high damping across the whole audio band. Full featured protection includes DC, overload, low impedance, shorts, under/overvoltage, overheating, and more.
The SP1-4000 Torpedo has very low idle power consumption (
<20 watts typical), which saves electricity in comparison with many pro audio and class AB amplifiers.
It includes gentle soft-start and long-term power limiter to reduce the chances of tripping breakers, and can do well in excess of 1/3 power with no time limit (convection cooling).
Available now, the SP1-4000 Torpedo, as well as the model SP1-2400 (2400 watts at 4 ohms, 6 pounds), are manufactured in Santa Ana, CA by SpeakerPower Inc.
