how to improve a subwoofer?

Answer 1

most good subwoofer's have their own amplifiers so that takes care of that.
The enemy of subwoofer's are things that viborate inside the housing or outside.
Make sure that the housing is anchored to the floor with spike probes.
sit nothing on the housing,keep things that could pick up harmonics away from speaker.
Most people say that it matters not where you sit the housing unit but i prefer to have it near the center of the room.
Sub woofers in automobiles are just noise makers and are not worth discussing.

Answer 2

Hi. Since a Subwoofer is mainly the extension of the bass of your 2 main front stereo speakers i would have 1 sub for each channel sitting as close as possible to each speaker because that way you are balancing the sound better.You can even put your main speakers on top of the sub(if they will fit) sitting on 3 isolation cones with the sub sitting on the floor with spikes under it.That way you will isolate vibration from the sub to your main speaker(it really does work).You can buy special metal isolation cones for this purpose.I use them under all of my equipment(someone is bound to contradict what i am saying but i have done this myself and if you set things up correctly this can be achived.Tannoy used to make a dual concentric speaker(tweeter inside the center of the woofer) with a 15 inch woofer in the one cabinet which went down to 15 HZ!)Subs are sometimes used with Electrostatic speakers to extend the bass which is sometimes missing with this type of speaker.They are attached to the top of the sub.

Although subs are omnidirectional the first sound you hear is the direct sound followed very quickly by the reflected sound.If you buy the subs made by the speaker manufacturer of your 2 front speakers then you can control at what frequency you want your subs to start with. By having 2 subs you wont get as much room resonances as you do with one and the volume level won't have to be as high when you have two.A good sub will have minimal cabinet vibrations if it is designed well. It should not rattle or buz at hige volume levels .
