You've got your woofers, your tweeters and your subwoofers, but now you need something to put them in. Whether the speakers in question are for your home entertainment center or your car, RV or SUV, speaker enclosures are more than just a box. Choosing the right type of speaker enclosures can help your system produce its best sound. The primary purpose of the speaker box is to keep the out-of-phase sound waves emanating from the rear of the speaker from combining with the positive phase sound waves coming from the front of the speaker. Such combining would lead to interference, especially in the lower frequencies. Speaker boxes must also be as rigid as possible to prevent unwanted resonance. There are many different designs for speaker enclosures, each of which addresses a specific problem. Some speaker boxes are meant to be used only with a specific audio component. The most common type of speaker box, however, is the bass reflex, since it addresses the problems in low frequency response, yet doesn't require the large size of an infinite-baffle enclosure. It is also less expensive and easier to design than a compound or band-pass enclosure. Bass reflex enclosures use passive radiating elements to transmit the sound waves from the rear of the speaker. These reflex ports are tuned by choosing the diameter and length that best suits the component. Bass reflex boxes are often lined with fiberglass to absorb extraneous waves that would cause distortion. No matter which kind of speaker boxes you're looking for, you'll find plenty to choose from here at eBay.
