The Sound Mechanics Of A Subwoofer

There are some people who purchase subwoofers with their stereo system, but never understand what it actually is or can do. A subwoofer is simply a loudspeaker that reproduces bass sound of frequency. Even though the range is limited they complement higher pitched sounds from any unit that has built-in speakers. If you ask any musician or enthusiast they prefer the deep tones a subwoofer can offer.

When you take a look at the Polk Audio PSW505 Subwoofer it has a frequency range of 23 Hz to 160 Hz. The point is; it will bring out the best of any musical performance. Over the years the engineers at Polk have tweaked the voice coil alignment. They've also added suspension in 12" long throw driver. This is called the Klippel Optimized Woofer. The end result is the extreme volume doesn't distort the sound. Most subwoofers you find out there have this problem all the time.

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.

Eventually you could find subwoofers just about anywhere, and thanks to them being able to keep the audience from experiencing a complete sound blast they became even more popular. The realistic sound has been modified over the years, but back then Bose Acoustimass offered a 6" driver per channel. Well, this was in 1987, but 25 years later you see the Polk Audio PSW505 Subwoofer offers a 12" Bass driver. Other benefits around this cover a 300-watt amplifier and an adjustable crossover, as well as a 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 Polk 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.

The creation of the subwoofer has evolved over the past twenty years to provide controlled bass tones to add to your home system and will never be a disappointment. Many people place small main or satellite speakers close to the stereo and spread four or five around the room to have a surround sound effect. Once you have your subwoofers set up, you'll wonder why you hadn't purchased sooner.
