PSB SubSeries 350 Subwoofer
PSB SubSeries: The PSB SubSeries 350 powered subwoofer is designed to provide the flattest possible frequency response, full bass extension, low distortion, and high output. The PSB SubSeries powered subwoofer is perfect for music and movie soundtracks.
Class D Discrete MOSFET Amp: The PSB SubSeries 350 powered subwoofer employs a custom-designed Class D discrete MOSFET amplifier rated at 300W RMS/900W Peak. The built-in digital amplifier features an automatic varying switching frequency that maintains maximum efficiency and low THD under all conditions. The Class D amplifier also incorporates proprietary limiting circuitry preventing audible overload while remaining true to the dynamics of your music or movie sound track. This circuitry combines peak limiting circuits that hold amplifier signal swing to the point just short of the amplifier's clipping, with compression circuitry that will reduce the amplifier's gain.
12" Woofer: To compliment the powerful Class D amplifier, the SubSeries 350 uses a front-firing 12" polypropylene cone woofer with rubber surround, high-temperature voice coil and vented pole piece. The woofer is designed to reduce mechanical noise and prevent harsh sounds at extreme excursion.
Sealed MDF Cabinet: The PSB SubSeries 350 features an acoustic suspension (sealed) MDF cabinet that is ultra-rigid and acoustically inert. It also comes with an acoustically transparent detachable grille. In addition, four vibration absorbing feet isolate the cabinet from your floor. As a result, the SubSeries 350 delivers tight, accurate bass that is uncoloured without distortion. The cabinet is finished in a high-gloss black.
Rear-Mounted Controls: Three rotary control knobs (Bass Level, Crossover, Phase) are provided on the rear-panel of the powered sub for setup.
Low-Level & High-Level Connectivity: The PSB SubSeries 350 powered subwoofer offers multiple connection options - including LFE, Stereo RCA, and Speaker-Level inputs and outputs. Gold-plated terminals are used for the powered sub's inputs and outputs, providing excellent signal transfer.
Auto On/Off: The powered subwoofer features a main power switch on the back panel. When switched to On, the subwoofer is initially in stand-by mode, awaiting the presence of an audio signal. When the signal is received, the subwoofer turns on automatically. When no signal is detected, the sub's amp will automatically turn off after approximately 15 minutes. In the Off position, the subwoofer will not power up. You can also setup the powered subwoofer to manually turn on and off with the main power switch.
Canada is almost as far away from New Zealand as you can get, but it seems we are close on more than just stunning scenery and a large neighbour.
We also appear to share similar tastes in a great sounding loudspeakers. For over 30-years Canadian speakers have been popular addition to New Zealand homes. The Canadian sound differs from USA and UK markets, with their scientific approach being woven into the DNA of their products for the last 4 decades.
Perhaps inspired by nature, science or both, PSB are among the most awarded and reviewed Canadian loudspeaker companies.
THE “NATURAL AND OPEN” CANADIAN SOUND: INSPIRED BY NATURE
In 1974, Paul met Dr. Floyd Toole, a world renowned psychoacoustician at the NRC, who conducted numerous studies to understand how sounds were interpreted by the human sense of hearing at both the psychological and physiological levels. To Paul, who had devoted much of his childhood to become an accomplished violinist, it was a “Eureka” moment. He had long puzzled over how to consistently reproduce on a set of speakers the unique timbres of different violins exactly as they would sound to him when he played them.
What Paul immediately recognised upon listening to Dr. Toole describe his research was that his findings gave him the formula he needed to design speakers that to the human sense of hearing, would be perceived as organic sounding.
In Dr. Toole, Paul found a lifelong friend and peer who would influence him and whom he influenced, all in the pursuit of a way to reproduce sounds that listeners would perceive as equivalent to that which was real, alive, and natural.
