PSB Speakers certainly knows its loudspeakers. However, when it came to a new direction for the company’s subwoofers, they did need a little help.
When designing a new powered subwoofer, PSB tapped into engineers at its sister company, NAD Electronics. The supergroup seemed like a no-brainer, since they both share the same speaker philosophy, as well as parent company Lenbrook. The end result is the new SubSeries 300 Powered Subwoofer.
Part of NAD’s contribution is a new Class D discrete MOSFET amplifier that can crank 850 watts of peak dynamic power, 425 watts of dynamic power, or 300 watts of continuous power (at less than 0.08 percent THD). Also, that output stage is 90 percent efficient, which means more power with less energy. Add in a newly designed power supply, and this unit can seriously cut down on power, without cutting well… the power behind your bass.
That’s not the only thing making music inside this compact cabinet. There’s a 12-inch woofer with a polypropylene cone, a butyl rubber surround, a high power 2-inch voice coil, and a 50-ounce magnet. Also, a 3-inch (diameter) down-firing port puts the kibosh on any port noise.
Whenever you are ready to rock, so is PSB. The SubSeries 300 Powered Subwoofer is available now with an MSRP of $899.
