The Polk Audio PSW505 is a very popular option among home theater enthusiasts. It’s high powered and produces quality audio for the cost, but we found that it’s limited by some fairly significant drawbacks. See this Polk Audio PSW505 review for more Polk Audio PSW505 specs.
The on-board amplifier develops power up to 300 W in continuous operation at a peak of 460 - which is very good for the AV class. There is a mode of automatic inclusion "on signal" and turning off the subwoofer in the 15-minute absence. The frequency response is 23Hz - 160Hz. Driver size is 12". The subwoofer will distinguish different sounds. Therefore, the calm, peaceful melodies will sound even clearer than you’re used to, while explosive, aggressive sounds may be heart thumping. Meanwhile, the noise-cancellation will eliminate all turbulence and distortion.
The driver located on the front panel of the American subwoofer makes a great impression: the 300th head with a cellulose diffuser coated with a polymer layer, a flat central dustproof insert and a wide polymer suspension. The magnetic screen allows you to position the unit close to the TV or even use it as a stand under 25 ". The case is made of 18mm MDF, while the thickness of the front panel reaches 25 mm - an effective method of attenuating vibrations. The walls are covered with tinted oak veneer. At the bottom of the back The panel is equipped with a slot-in phase inverter port (Slot Load Vent) designed to minimize spurious noise of the air flow. High-amplitude inputs and outputs (screw terminals) are short-circuited.
At the front, you can take off the subwoofer’s front grille. At the back, you have a line and speaker-level inputs and outputs. You also have a toggle switch so you can run additional subwoofers. There’s also a precise volume control at the back so you can merge the subwoofer with any set of speakers. There are two line inputs plus an LFE input for a special signal from the AV receiver.
