PSB SubSeries 450 Subwoofer

"Unsurpassed" Compact and Extremely Powerful Sub

PSB's SubSeries 450 is a compact, yet very powerful, subwoofer housed in a beautifully finished fine furniture cabinet. PSB's legendary design and engineering prowess is evident in the choice of a 12" active woofer supported by two 10" passive radiators (PR). This sub is dead flat to 20Hz and can produce well in excess of 100dB sound pressure level at these 'felt not heard' extremes. There is plentiful power to reproduce movie sound effects at lifelike levels. The SubSeries 450 is also exceptionally accurate and musical, and it can clearly enunciate the full power and majesty of a live symphony orchestra.

The SubSeries 450 stands at the head of a range of PSB subwoofers renowned for their exceptional performance and value. Whether for music or movies, the SubSeries 450 subwoofer delivers powerful, tight, accurate bass that is truly exciting to experience.

"Not Surpassed by Monster Models Costing Twice As Much"

"I was unable to find any material capable of pushing the SubSeries 450 past its limits," reports Brent Butterworth in his August 29, 2016 review for hometheaterreview.com. "Plus, it has pitch definition and precision that's at least the equal of any sub I've tried, AND it's compact and handsome enough to be welcome in most living rooms. None of the hundreds of subwoofers I've tested can truly do it all, but the SubSeries 450 comes as close to that description as any I've found."

“Its ability to deliver dead-flat LF response down to 20Hz is equaled and, perhaps or perhaps not, surpassed by monster models costing twice as much," notes soundstagehifi.com, October 1, 2016.

12" Active Woofer and Passive Radiators

The 12" active woofer is built on a powerful motor using 75oz magnet and 2-3/4" voice coil for high efficiency and power handling. The 6" spider assures perfect alignment at high SPLs which directly translates into very low distortion. The polypropylene cone offers an ideal combination of stiffness and damping. Combined with a 1" rubber surround, this driver can respond to the lowest frequencies while maintaining perfect pistonic motion without 'cone breakup' often encountered on lesser drivers.

To extend bass response into the infrasonic region, two 10" passive radiators are used to sum the back wave output of the woofer with the front wave. The passive radiators are free of any wind noise or 'port chuff' that can be a problem at very high sound pressures.

Advanced Amplifier

The SubSeries 450 employs a very advanced amplifier developed by NAD specifically for this application. The massive power supply, capable of the instantaneous high current required for accurate and powerful bass response, is combined with an advanced Class D output stage. 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.

DSP Control Maximizes Performance

The use of digital signal processing has allowed PSB's engineering team to maximize all aspects of performance, including low bass extension with low distortion, freedom from overload, and ideal crossover characteristics. Adjustments for crossover frequency and level, as well as variable phase/delay, perfectly align the woofer with the full range speakers in the acoustic system.

Truly Astonishing Low Bass Reproduction

The careful engineering and precision manufacture of the SubSeries 450 results in truly astounding performance, especially considering the compact dimensions of this top of the line subwoofer. Truly flat response at 20Hz is accurately reproduced, bringing motion picture sound tracks to life. Music also benefits mightily from the low bass extension of a good subwoofer, opening up the sound stage 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.

"The PSB SubSeries 450 DSP-controlled subwoofer cuts edges that I’m not sure anyone knew existed. Its ability to deliver dead-flat LF response down to 20Hz is equaled and, perhaps or perhaps not, surpassed by monster models costing twice as much."

"PSB has succeeded in bringing Big Box subwoofer sound to a Smaller Box product -- no longer do you have to court a hernia lugging an 85-pound sub around the room to get Big Box sound. PSB has not only cut the edge but stropped it razor sharp; it’s a bold statement, and a challenge to all other makers of subwoofers."
