Guidelines on buying a subwoofer

Subwoofers are a very important part of your overall listening experience and can change your home theatre by providing a truly immersive movie-watching experience. With a subwoofer, you can make out the difference between a good-sounding and a great-sounding system. But, choosing a subwoofer can be a little puzzling! So check out the following guidelines to find one that works with your setup.

First of all u need to understand what type of sound are you looking for? There are two main types in the sound world: Sound Quality (SQ) or Sound Pressure Level (SPL). Sound Quality, a very linear response that is not loud and is very controlled, especially when listening to complex software. Generally an SQ System uses a smaller woofer and requires a smaller enclosed space. A sealed enclosure would normally work best for this purpose. SPL, on the other hand, if u like a lot of impact with your music (extended bass response) then you're probably looking for a ported enclosure.

If you want a system that really booms, there's no substitute for plenty of power. Focus on to RMS power ratings. RMS ratings gauge continuous power handling or output and are a much more practical measure than peak power. Make sure you match the sub's power handling to your amp's power output.

Sensitivity and power goes hand-in-hand to achieve high output. A subwoofer that has a high sensitivity rating require less power to generate the same amount of sound as a model with a lower sensitivity rating.

Frequency range gives you a thought of how low a sub can play. So keep in mind, that the actual performance of the subwoofer can depend on a lot of variables, such as the box type it's mounted in.

Enclosure type - The kind of enclosure a subwoofer is mounted in will have a big effect on the kind of sound it produces. while ported and band pass enclosures produce more volume, the sealed boxes give you the deepest, most accurate sound.

Numbers of voice coils -- dual/twin voice coil subwoofers are famous among car audio enthusiasts who want additional flexibility in wiring their sound system. Dual voice coil subwoofers use their coils separately. Each coil has its own connection, mounted on one cylinder which is connected to a common cone.

Size of the woofer - It's an everlasting question. What size of subwoofers would play loudest and lowest? You must consider enclosure type, sensitivity and available power. If your ultimate target is to have a system that plays loud and low, and if space isn't an issue then go for the biggest subwoofers. But don't underrate smaller subwoofers. Appropriately powered and in the right enclosure, smaller subs can put out a lot of sound.

Impedance - When you've chosen a subwoofer, look for amplifiers that will match up to your subwoofers in terms of power rating and impedance. There are a wide variety of amplifiers available in the market, so you will have no trouble finding one that will bring out the best in the subwoofer you've chosen.
