Also known as "efficiency" it relates to how loud the speaker will sound when compared to other speakers driven by the same signal, from the same amplifier. Sensitivity: This measurement refers to the volume (or sound pressure level) produced with 1 watt of input. The Stage A120 has a nominal impedance of 6 ohms so is recommended for use with an amplifier that specifies a matching speaker impedance range. You should check your speaker’s impedance rating to ensure it matches the rating for the amp that will be driving it. Impedance is typically rated at 4 to 8 ohms. Impedance: In simple terms this means the resistance a speaker gives to the signal it receives from an amplifier. For the Stage A120 this is 20 – 125W (Watts). This specification can be sometimes be expressed as "recommended amplifier power". Rated power (also known as nominal or continuous power): This is the amount of power a speaker is designed to handle before damage could occur. For example the JBL Stage A120 has a frequency response of 60Hz – 40kHz. Let’s cut through the jargon and look at a few specifications you need to pay attention to.įrequency Response: This refers to the range of frequencies a speaker is able to reproduce within a certain variance limit.
Usually contained in a separate enclosure a "subwoofer" has the job of reproducing very low frequencies.
RED JBL SPEAKER DRIVERS
Sometimes multiple drivers are added to improve power handling or further divide the allocation of frequencies.
RED JBL SPEAKER DRIVER
The components usually include a "woofer" (for low frequencies), a mid range driver and a "tweeter" for high frequencies. These may be tasked with reproducing the full audio spectrum or may be dedicated to specific parts of it. In a typical speaker cabinet, or enclosure, you will find "drivers" (sometimes called transducers). Which is best? It depends who you ask but at the end of the day it's the fidelity of the sound that reaches your ears and how you perceive that sound that matters. Each has their advantages and disadvantages and is chosen by different listeners depending on their overall sound characteristics. There are many different designs and construction methods used including reflex (or ported), sealed (or closed), electrostatic, transmission line and horn. It's the final link in the sound reproduction chain and tends to be the most limiting.which is why sound professionals and audiophiles alike place a great deal of importance on them. The term "loudspeaker" or "speaker" basically refers to a device which converts an electrical signal into sound.
