The ideal frequency response for a speaker is very flat. This means the speaker would be the same level at low frequency as it is in the mids or highs. The goal of a flat frequency response is to ensure that the people listening to your music experience it the way you intended it.
If your track is well mastered and sounds good on speakers with a flat response, you can be sure that it will sound its best on any playback system. Many speakers are not flat.
Some do not have enough treble or enough bass, or they have peaks or dips in their frequency response where certain frequency ranges are over emphasized or hidden or masked. If this happens some instruments may be louder or softer than you intended them to be and the mix you worked so hard on will not be properly represented.
For high frequencies, speakers must move very quickly. For low frequencies, speakers must push a lot of air. This is why tweeters high-frequency drivers are typically small domes and woofers low frequency drivers are usually large cones.
We hear 10 octaves 20hzkHz that is a very wide range for comparison, we can only see less than one octave of light. Many speakers we use have limited frequency responses. For example: Try to hear the bass kick on your laptop speakers! No thump right? Most speakers also have lower output power. Ever try using your phone to play music at a party? A lot of speakers also produce distortions, meaning they add frequencies to the music that were not there in the original recording.
While there are times when distortion can sound good think tubes and Eddie Van Halen speaker distortion often sounds bad unless it was put there by choice. Larger speakers are, on average, much better in terms of their frequency response and distortion but a big improvement would be to be able to produce better, more accurate sound from smaller speakers.
For example, "tallest building". Search within a range of numbers Put.. Combine searches Put "OR" between each search query. For example, marathon OR race. Physics of the Guitar. These speakers have two sizes of speaker driver: tweeters above and woofers below.
There are several reasons why speakers use multiple drivers in different sizes. While it is true that a single driver can cover almost all the audible spectrum by itself, there are a number of limitations it runs up against. Learn more: Driver types explained. Larger drivers can move more air, but the problem is that speakers become more directional as the frequencies they are reproducing go up.
This is known as beaming. As frequency increases, the associated wavelength decreases; speaker drivers usually start beaming at a frequency with a wavelength equal to the diameter of the radiating cone. The simple solution is to use different sizes of drivers with each one tailored to reproducing a specific range of frequencies —different parts of the audible spectrum bass and treble, or bass, middle, treble.
This concept works in tandem with a frequency dividing network in the speaker box called a crossover. A crossover delegates the right frequency range to each driver type: tweeters for the highs and woofers for the lows.
A little base knowledge will help you understand why certain design decisions were made, how they influence the sound, and to help you identify snake oil salesmen. Knowing how speakers work can also help you diagnose problems.
