8/29/2023 0 Comments Polk audio psw100Low-frequency potential of PSW1000 is so great that sometimes there is a desire to take it in hand. Sincere zeal while playing the lowest bass awakens a storm of emotions, when you literally all over feel infrasound component. Actually, I expected this from already first minutes of knowing (seeing as the potential is visible to the naked eye). The low-frequency power of the American subwoofer is taken for granted. Also it has boost button, which like loudness increases bass return on 3 db. Cutoff frequency and volume level controls are placed on the front panel for convenience. The phase can only be inverted (0 and 180 degrees) automatic turn on by the input signal is provided. Its nominal power is 400 W at peak of 825, so there shouldn't be problems with dynamics. An amplifier of BASH type, which combines the advantages of AB class and ultra-efficient pulse cascades, was used in the Polk Audio PSW1000 sub. The total area is equivalent to 300-mm head, but at the same time the emitters of smaller caliber obviously win by pulse indicators. Two 10-inch own-produced drivers with polymer membranes made by Dynamic Balance principle are installed on them. The model PSW1000 is made in very massive case of bass-reflex type (by the branded Power Port technology) with the system of internal struts and side panels with the thickness of 4.5 cm.
