To replace the SVS SB-1000 and PB-1000 subwoofer models, SVS has prepared the new SB-2000 and PB-2000, which are not much different from their predecessors, but equipped with new speakers and amplifiers. But here we’ll see only the SVS PB-2000 review.
Concerning SVS PB-2000 specs, subwoofer uses 12-inch speaker and a 500 W DSP-controlled digital amplifier. The peak power of the amplifier can reach 1100 watts. The operating frequency range of the model starts from 16 Hz. In this subwoofer, a Class D Power Sledge STA-550D amplifier is installed on discrete MOSFETs in the output stage. The signal for the amplifier is processed by a 50-MHz DSP with 56-bit filtering. SVS Subwoofer DSP Smartphone application, available not only for Apple iOS and Android devices, but also on Amazon devices. In addition, the STA-500D has other advantages: DSP-controls for fine tuning, an array of filters, volume, gain, phase control. The amplifier also has a frequency-independent limiter / compressor algorithm with adjustable attack / recovery and compression parameters to protect against accidental volume expansion.
The model PB-2000 has a phase inverter design and a significantly larger case. Enhanced bass response of this model is more consistent with the cinema use of the device. There are volume control, tuning and selection of user presets, 3-band parametric equalizer, low-pass filter, phase, polarity adjustment, correction of the influence of the room, port settings.
The PB-2000 lacks the former's five-way binding posts for speaker-level input and features a C17/C18 power coupler in place of the PB-1000's C7/C8 connection. Other than that, all of the ins and outs are the same. The PB-2000 features stereo line-level RCA inputs and outputs (the right of which serves as the LFE in), a 3-12-volt trigger input, a dipswitch to toggle between on and auto standby, and knobs for volume/gain, phase control, and a low-pass filter that runs from 50 to 160 Hz on its way to the LFE/bypass setting.
