Features

Rated 4.7 Out off 5.0*

Speaking about useful features of Polk Audio PSW505, this subwoofer provides two modes of automatic activation - "on signal" and the turn of the volume controller. Also, always active is the mode of disconnecting the subwoofer when it is not available for 15 minutes. The digital amplifier is rated at 300 watts continuous, and 460 watts peak with program material. The woofer is made of cellulose and polymer. These materials allow it to remain as durable and flexible as possible in order to withstand the maximum load during operation. In total, it gives a reliable and durable construction where all major amplifier plate penetrations are sealed with glue to prevent air leaks. The control layout is logical, and the toggle switches and rotary knobs have a quality feel and smooth operation.

Performance & Sound Quality

Rated 4.8 Out off 5.0*

Polk Audio PSW505 has a broad amplitude of frequency from 23 Hz to 160 Hz and is able to generate the low-end bass notes with incredible clarity. When I started tuning the subwoofer to my audio system, I realized how deep sounds the subwoofer gives out. For a comfortable sound in the house, it's only necessary to slightly shift the volume control. The more I twisted it, the more trembling grew in the whole house. To achieve maximum clarity of bass, Polk PSW505 should be guided by the possibilities of satellites. I used the 5.1 system and adjusted the subwoofer to it. At frequencies below 35Hz, the bass does not lose quality. When you raise the volume by 1/4 and the frequency to the middle position, the sound becomes clear and distinct, the bass guitar and percussion instruments are perfectly audible. Music with Polk PSW505 sounded clean; bit and bass in hip-hop compositions sound exactly, and in the records of rock concerts you can hear even the squeak of bass guitar strings.

Setup

Rated 4.9 Out off 5.0*

I tested Polk Audio PSW505 with my home theater system. This system has five small satellites for reproducing high and medium frequencies and sound. Polk setting was really easy. I wired up the subwoofer to the system thanks to speaker level terminals. I coordinated the subwoofer with the rest of the audio system using the phase switch. For the correct operation of the multiband system, it is necessary that the diffusers of all loudspeakers move in phase. Then I chose a comfortable volume level and a suitable frequency. A really loud sound appears after the slightest turn of the controller.
