PSB Debuts SubSeries 450 12-Inch Subwoofer

By |


PSB-SubSeries-450.jpgIn March, PSB will introduce a new subwoofer that the company calls its most advanced subwoofer to date. The new SubSeries 450 combines a 12-inch woofer with two 10-inch passive radiators in a 16-inch-cube, gloss-black cabinet. The drivers are powered by a 400-watt Hypex Class D amplifier designed by PSB's sister company NAD Electronics. The SubSeries 450 will carry an MSRP of $1,499.

From PSB
PSB Speakers debuted an all new high-performance subwoofer, the SubSeries 450 featuring for the first time an advanced 400W RMS (1,000W peak power) Class D amplifier designed by sister brand NAD with DSP control. PSB's most advanced subwoofer to date, the SubSeries 450 is a compact yet powerful design that will deliver superlative performance for either music or home theater applications. Housed in a stylish gloss black cubic cabinet, the unique design 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.

PSB SubSeries 450
The careful engineering and precision manufacture of the SubSeries 450 provides exceptional performance, especially considering the ultra-compact dimensions if this 16" cube. Truly flat response to 20 Hz is seldom achieved, especially at the high SPLs required to accurately reproduce the sound effects of today's motion picture sound tracks, yet the SubSeries 450 delivers. Music also benefits from the low bass extension of a high performance subwoofer, opening up the soundstage and reproducing the atmosphere of a good live recording. Instruments rich in low frequencies, from pipe organs and timpani to basses and synthesizers, all benefit from the tight, accurate, and powerful response of PSB's best ever subwoofer.

DSP Control
The use of digital signal processing has allowed PSB's engineering team to maximize all aspects of performance; low bass extension with low distortion, freedom from overload, and ideal crossover characteristics. This precision is simply not possible with the old analog filters still used in lesser subwoofers. The SubSeries 450 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 powerful motor using a 50oz magnet and 2" (70mm) voice coil for high efficiency and power handling. The 6" (152mm) spider assures precise alignment at high SPLs that directly translates into ultra low distortion. The treated felt cone offers an ideal combination of stiffness and damping and is impervious to variations in humidity. Combined with a 1" (25mm) rubber surround this driver can respond to the lowest frequencies while maintaining perfect piston motion without the 'cone breakup' often encountered on lesser 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 are free of any wind noise or 'port chuff' that can be a problem at very low frequencies and high sound pressures.

Advanced Amplification
The SubSeries 450 employs an advanced amplifier developed by sister company NAD specifically for this application. A massive, tightly regulated, 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. In addition to nearly immeasurable distortion, this amplifier features an extremely high damping factor and high current output, two of the most important parameters for tight and powerful bass output. It is also highly efficient and includes a very low power (<0.5W) standby mode, making the woofer instantly available yet very low in power consumption.

Like all PSB speakers, final voicing is performed by Founder and Chief Designer, Paul Barton, at Canada's famed National Research Council. PSB's research has discovered how listener preferences can be integrated into a wide range of speaker designs for many different applications, yet all featuring consistent sound quality that is natural and lifelike.

"Whether for music or movies, a well-designed, properly integrated subwoofer can be the difference between good and exceptional sound," commented Paul Barton, Founder and Chief Designer of PSB Speakers. "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."

Key Features of the PSB SS450:
• 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
