PSB introduces SubSeries 450 powered subwoofer
PSB Speakers has introduced its new subwoofer, the SubSeries 450. The Subwoofer includes an advanced 400W RMS (1,000W peak power) Class D amplifier designed by sister brand NAD with DSP control.
According to PSB, the subwoofer includes:
The Subwoofer uses digital signal processing to create low bass extension with low distortion, freedom from overload and specific crossover characteristics. It includes adjustments for crossover frequency and level, as well as variable delay to acoustically align the woofer properly with the full range speakers in the system.
High Performance Drivers
The 12” (30cm) active woofer is built on a motor using a 50oz magnet and 2” (70mm) voice coil for high efficiency and power handling. The 6” (152mm) spider creates an alignment at high SPLs that directly translates into ultra low distortion. The treated felt cone creates a combination of stiffness and damping and is made to be resistant to variations in humidity.
Combined with a 1” (25mm) rubber surround this driver is made to respond to low frequencies while maintaining the right piston motion without the ‘cone breakup’ sometimes encountered on other drivers.
To extend bass response into the infrasonic region, PSB has specified two 10” (25cm) passive radiators to sum the back wave output of the woofer with the front wave. While similar in action to a ported enclosure, the PRs do not have any wind noise or ‘port chuff’ that can occur at very low frequencies and high sound pressures.
The SubSeries 450 employs an advanced amplifier developed by sister company NAD for this application. A switch mode power supply is capable of the instantaneous high current required for accurate and powerful bass response. This is combined with one of the most advanced Class D architectures available, which is licensed from Hypex in the Netherlands. This amplifier features an extremely high damping factor and high current output. It is also includes a very low power (<0.5W) standby mode, making the woofer instantly available yet very low in power consumption.
Features of the PSB SS450 include:
- PSB’s most advanced subwoofer to date
- DSP Control maximizes all aspects of subwoofer’s performance
- 400W RMS (1,000W peak power) amplifier custom designed by NAD using Hypex Class D technology
- Bass reflex design utilizing active 12” woofer
- Stylish, curved, gloss black cabinet
Like all PSB speakers, final voicing is performed by Founder and Chief Designer, Paul Barton, at Canada’s famed National Research Council.
“Whether for music or movies, a well-designed, properly integrated subwoofer can be the difference between good and exceptional sound,” Barton, said in a statement.
“The SubSeries 450 was designed using the same proven methods that PSB has employed for decades. The result is a subwoofer that is powerful, precise and truly exciting to experience.”
The SubSeries 450 resides in a gloss black cubic cabinet. It features a 12” active woofer supported by twin 10” passive radiators. The SubSeries 450 will be available in March 2016 at a MSRP of $1499.
