Yesterday we covered Car audio subwoofer enclosures. Today we will talk about home audio! Home audio is quite a different market than car audio as far as subwoofers are concerned. Almost everyone who buys a subwoofer for their house buys it as an all in one package. Meaning that the actual speaker driver, amplifier and enclosure all come together, and you cant mix and match like in car audio. This makes it rather easy to pick a subwoofer out. Go to the store, and see which one is the loudest, and sounds the best to you! There are a few DIY'ers like Loudsystem and myself who build our own subwoofer boxes, pick out the drivers ourselves, and buy an amplifier that works accordingly. This offers a few benifits. First is cost. To get the level of performance from a DIY subwoofer, you almost always have to spend 2 to 10 times as much from a retail unit, depending on several factors. Second is you get to pick the enclosure size, type and asthetics. This is handy because you can match the subwoofer to your decor, you can build a large enclosure for more output, and pick the type of enclosure that is best for your listening tastes and room. Since hardly anyone actually builds their own, this tutorial will cover setting up premade subwoofers properly, and knowing what subwoofer is best to buy for you. First, evaluate your listening habits. Do you listen to rap with thundering bass, or classical and want to feel the pipe organ fundamentals throughout your body? Or maybe you listen to rock, which might need a little of both? One thing to note is that any subwoofer will sound different depending on the room you place it in. It will also sound different in regards to where you place it in the room, and where your listening position is. So keep this in mind when purchasing. Knowing your habits, it is now time to go audition the subwoofer. Subwoofers are a bit easier to compare from one another, because they cover such a narrow frequency band. Most people also purchase based on loudness too, and it is pretty easy to tell if one unit is louder than another. Also note what size subwoofer you can have. The larger the enclosure, generally the more bass. I for instance have a 8 cubic foot enclosure. It takes up an entire corner of my room. Most people don't have this kind of space available. I can only think of one commercially available subwoofer that is a sealed box design, the adire rava. So unless you pick that one, you are most likely going to go with vented. So, how do you know what subwoofer size to get? One with a 8" speaker, a 12" speaker, even a 15" one? The answer to this is that it depends on how much output you want. A 15" will have the same sound quality of an 8" if designed correctly. But the 8" would have to be extremely hard core to be able to displace more air, and in turn be louder than a 15". So keep these things in mind. So you have bought your new subwoofer and it is time to put it in your room. Where do you put it??? The best place to put it is almost always the corner. And there is a very good reason for this. If you read yesterday's post, I touched on the subject of boundry reinforcement. Well it works in the home too! With every boundry you add, you gain 3dB. For instance, lets say you had the subwoofer in the middle of a footballl field. You would get 3dB of boundry reinforcement from the ground. If you put it against the wall you would gain 6dB. And if you put it in the corner, you now have 9dB!!! so, by putting the woofer in a corner rather than the wall, you gain 3dB! This is a considerable amount. The downside of putting the woofer in the corner is that there can be peaks and valleys in the response of the subwoofer, making it not sound as "accurate". So you will have to experiment on your own to find what place in the room offers the best sound for you. Feel free to ask any more questions in this thread!
