Setting Up A Subwoofer For Max Efficiency
A subwoofer, or sub for short, is nothing more than a loudspeaker that reproduces the bass sound of the frequency. They have a limited frequency range but contrast nicely with the higher pitched sounds from an audio unit with built-in speakers. Musicians and music enthusiasts often prefer the deep tones that subwoofers produce above the typical bass sound.
The Polk Audio PSW505 Subwoofer demonstrates how a frequency range of 23 Hz to 160 Hz can make a difference in tone and crispness when using subs to bring out the best of a musical performance. Engineers of Polk have been able to tweak the voice coil alignment and suspension in the 12-inch long throw driver, called the Klippel Optimized Woofer. By achieving this, extreme volume will not distort the sound, a problem that many subwoofers have.
Back in the 60s it was a time for experimenting with music. Usually the louder the better, but the "screechy" sound wasn't very inviting so Ken Kreisel decided to take a different approach. Over the next decade he perfected a electrostatic speaker system. This came with a woofer so the frequency range would be lower. Unfortunately it wasn't until 1973 that the first subwoofer was tested professionally. This is was done by Steely Dan while making Pretzel Logic. Throughout the next 7 years there were various scenario, but just 3 years later we saw 300 Sensurround systems throughout several theaters. It provided a great way to help with sound effects in movies.
Subs became so popular we started seeing them in concert and movie establishments all around the country. It kept from making the sound "blast" the audience back, and instead worked with the main speakers to provide a realistic sound. Bose Acoustimass offered a 6" driver per channel back in 1987. Almost 25 years later the Polk Audio PSW505 gives you a 12" Bass driver, which is well above any of their competition. It also gives you a 300-watt amplifier, as well as an adjustable crossover and magnetic shielding.
High volumes can often drag a subwoofer across the floor from the shear vibration of frequency so always check the bottom feet for sturdiness and steadfast material. The PSW505 Subwoofer comes with this feature because you will need it in testing the highs and lows of its capability to create just the right balance for your movies, music shows and games.
Over the last two decades the subwoofer has evolved into a very unique approach to optimal sound. Their controlled bass tones mesh well with any home system, which means you will never be disappointment. You can spread your speakers around however you wish, but the small main or satellite speakers should be close to the stereo, and then the other 4 or 5 can be spread out around the room. When it's all said and done you will truly enjoy your subwoofers every time they are used.
