The model's 17-inch driver is equipped with a fiberglass composite diffuser on a long-stroke SBR external rubber suspension. The corresponding ferrite magnet weighs 25 kg. As a result, the lower frequency limit declared for new products was 15 Hz for SB 17-Ultra and 12 Hz for PB 17-Ultra.
PB-2000 Pro (frequency response from 16 Hz, cubic housing). The acoustic design of all models is phase-inverted, the speakers are identical everywhere - branded 12' with aluminum diffusers and a dual magnetic system.
The PB4000 is a basic subwoofer at every level with unheard-of performance and features even twice the price. The advanced DSP amplifier creates three port tuning modes, each with individual response curves to achieve the most accurate frequency response in the room.
The 13.5" drivers of the model are custom-made by SVS and feature a (nearly) 40-pound dual-magnet motor. SVS has reduced lightness and rigidity, and added the ability to handle the 1,200 watts that the amplifier outputs. The cases are made of two-layer MDF with internal fixation to suppress resonances.
The SVS PB-3000 is equipped with a 13-inch long-stroke speaker and a Sledge STA-800D2 amplifier module that combines "high current MOSFET transistors and Class D circuit efficiency." The PB-3000 also features a new long-stroke bass speaker and 800-watt amplifiers capable of delivering up to 2,500 watts at peak power.
