The Polk PSW505 Subwoofer is a single powered stereo and home theater speaker system. It can handle up to 460 Watts, 360 Watts continuously. It is designed in such a way that there is minimum disturbance from speaker turbulence, noise and distortion. This low disturbance helps emphasize the bass line from the speakers. The subwoofer is also magnetically shielded. This shielding helps protect the subwoofer from other technology. Technology close to the subwoofer is also protected from the subwoofer’s electrical outputs, so you don’t need to design or install a special shelf far away from other technology.

The Polk PSW505 Subwoofer augments a range of frequencies, from 23HZ to 160 HZ. This wide range of frequencies adds more color to both music and movies. You can easily hear a bass line that you had to strain to hear before. The added sound adds drama and feeling to the sound in the room, making for a more enjoyable experience.

Some features included with the Polk PSW 505 Subwoofer are an adjustable low-pass crossover, phase switch and volume control that can be used with your other speakers. There is also an on/off circuit. This circuit makes using the subwoofer even more convenient. If the circuit does not sense a program signal for 15 minutes it will automatically turn off. It will turn on again as soon as it senses a signal.

For large rooms the Polk PSW505 Subwoofer is an ideal system. It easily throws the sound throughout the room. A large home theater will be improved with the more accurate bass line, especially if that bass line can be heard throughout the room. The bass line is not important only in contemporary music and action packed videos; it will also augment the delicate bass line of a classical concert. With all these uses, the subwoofer will be an excellent addition to your home theater.
