About Speakers
A speaker is an electromechanical transducer that converts an electrical signal to sound. A speaker system incorporates one or more drivers and additional electronic components. Speakers are the most variable element of an audio system and are important in determining how much you will enjoy Music or Home Theater / HDTV.
A 2-way speaker has two drivers, (1 tweeter & 1 woofer) which accommodate upper frequencies and mid-to-low frequencies.
A 3-way speaker has three drivers, (1 tweeter for high frequencies, 1 mid-range driver for medium frequencies, and 1 woofer for lower frequencies.
Combining one or more drivers into an enclosure to make a speaker system, is both an art and science.
A subwoofer is a woofer driver used for the lowest audio frequencies, usually below 120 Hz. To reproduce very low bass notes without unwanted vibration from speakers cabinet panels, subwoofer systems must be solidly constructed. High quality subwoofers are usually heavy. Many subwoofers have controls relevant to low frequency reproduction. These are known as "active subwoofers". Passive subwoofers require external amplification.
A Crossover is used in multi-driver speaker systems,and separates the input signal into different frequency ranges appropriate for each driver. Each driver receives the frequency range it was designed for, so the distortion and interference between drivers is reduced.
Most speaker systems consist of drivers mounted in an enclosure, or cabinet to provide a place to mount the drivers and to prevent sound waves from the back of a driver from interfering with those from the front. System designers align drivers by moving one or more drivers forward or back, so that the acoustic center of each driver is in the same vertical plane. This may also involve tilting the face speaker back, or providing separate mounting for each driver, or using other techniques which in some instances account for some unusual cabinet designs.
Most speakers use two wiring points to connect to the source of the signal (i.e. the audio amplifier or receiver), by binding posts or spring clips. If the wires for left and right speakers) are not connected 'in phase' with each other (the + and - connections on the speaker and amplifier should be connected + to + and - to -) the speakers will not preform correctly.

Sensitivity is the speakers ability to convert power into sound. It is measured using of 1 watt/1 meter. This means a microphone is placed 1 meter away from the speaker to measure the sound output in decibels (dB) with 1 watt of sound played through it.
Impedance is the speakers resistance to power or impeding the flow of power. Most speakers are rated at an Impedance of 8 ohms.
