The PSW111 model is manufacturer-oriented for home use in entry-level and mid-level musical and theater complexes installed in small rooms. This is a relatively modest externally unit with a simple (but quite high-quality) black vinyl trim, which is more likely characteristic of professional models. Moreover, in this case, such a solution does not spoil the appearance of the device, but rather succinctly emphasizes the absence of "extra" elements. See more insights in this Polk Audio PSW111 review.
Concerning Polk Audio PSW111 specs, the subwoofer is built on a proprietary 8-inch long-stroke head with a Dynamic Balance membrane located on the front panel of the case. The phase inverter provided by the developers is called upon to expand the reproducible range down; its port is located on the lower edge of the case. The built-in amplifier is surprisingly powerful for such a compact system - up to 300 watts in peak. The cutoff frequency is continuously adjustable in the range from 80 to 200 Hz. The phase is switched by a 0/180 degree toggle switch.
The cube-sized enclosure combines many of the company's advanced technologies developed in the field of acoustics of this class. This compact subwoofer is perfect for even in small rooms where it will be almost invisible, but will provide powerful, fast and quite deep bass. Such characteristics of the Polk Audio PSW 111 were ensured by the use of the proprietary Dynamic Balance concept - a combination of correctly selected woofer materials, housing geometry, electronic circuitry for precise engineering calculations. The diffuser suspension was also precisely matched for flexibility in order to ensure its free movement with large amplitude and at the same time to dampen any spurious vibrations. The woofer diffuser is made of composite material, due to which, with a small mass, it has high mechanical rigidity.
Switching capabilities are also on the level - there are both linear inputs and high-level ones. Dedicated LFE input for integration into a multi-channel home theater system.
