Dynamic Audio

Most receivers and speakers have a specific frequency range in which they are most powerful. In some cases, this is intentional. For example, subwoofers are intended to capture the lowest frequencies, and consequently are specialized for the accurate reproduction of bass sounds. In other cases, this is not intentional, but rather a result of the fact that no single component is really and truly balanced across the full dynamic and frequency ranges. In order to produce dynamic audio, you have to get the best possible equipment, and give it the advantage of the best accessories you can find.

It used to be the case that you could use lower quality speakers for the rear pair in a surround sound system because they were not as important as the front three channels. If your plan is to reproduce the sound quality that you experienced in a theater, however, your rear speakers will have to be of good quality. If the action of a movie is moving around you, you should be able to hear the sound travel from left to right and front to back.

Receivers, Speakers, and Cables Are All Part of Capturing Dynamic Audio

Capturing dynamic audio is just as important (if not more so) to audiophiles. If you really love music and savor the nuances of a layered studio recording, you know that some receivers and speakers simply don't capture everything that's going on in a song. Sometime you have the option to equalize the sound however you like it, but you still can't bring out the clarity of a martial roll on the snare, or the rich warmth of a cello line amidst an array of electric instruments. If you want to be able to take advantage of the equalizer on a good receiver, you must have cables and speakers which deliver the modified sound accurately.

New audio formats such as SACD and DVD-A allow for multi-channel sound. This means that each speaker in your system is able to play different sounds. If any part of your speaker system is deficient, the entire system will seem unbalanced. Not only must your receiver and speakers be of high quality, your cables must be as well. Time correction is a crucial attribute of good cable for dynamic audio, as without time correction, high frequencies will travel along cables faster and you will hear them out of synch with lower frequencies.
