ONKYO How-To Series: Connect Speakers
A note about amplifiers:
You essentially have 3 speakers you want to connect together to act as a single speaker. Assuming each has a nominal impedance (lets simplify as resistance) of 8 ohms, if connected in parallel, the amp will see an impedance of ohms, which is. 10 May When using more than one speaker with your amp the equivalent overall impedance changes depending on how the speakers are wired. You can wire multiple speakers "in series," "in parallel" or in a combination of the two wiring configurations ("series/parallel"). Speakers also have a wattage rating which. Wiring up Speakers correctly to provide the best possible sound, requires some knowledge of Loading, Phase, and Impedance, while understanding Ohms Law will help you to connect your speakers properly. Although we discuss here two ways to wiring Speakers - Series and Parallel, we should mention Series/ Parallel.
Decibel Calculator for Audio voltage. You can do the same for the series connections below as they are also the same as each other. Many of them can't even provide their rated power into 8 ohms, let alone 4.
When using more than one speaker with your amp the equivalent overall impedance changes depending on how the speakers are wired. Speakers also have a wattage rating which indicates source much power from the amp they can handle before being damaged. When you use multiple speakers, the output power from the amplifier will be distributed among the speakers.
We recommend using speakers with the same ohm rating in multi-speaker cabinets so that the power is evenly distributed to each speaker.
For guitar amplification, we recommend choosing a speaker rated for at least twice the maxiumum power it could experience from the amp. In this case we recommend choosing an 8 ohm speaker with a rated power of at least W. Since there are two speakers, each speaker could experience 25W half of the output power from the amp.

In this case we recommend choosing two 4 ohm speakers with rated power of at least 50W each. Since there are two speakers, each speaker could experience 25W half the output power from the amp.
In this case we recommend choosing two 16 ohm speakers with rated power of at least 50W each. Since there are four speakers, each speaker could experience In this case we recommend choosing four 8 ohm speakers with rated power of at least 25W each.
For this configuration, it is easiest to calculate the equivalent overall impedance in two steps. Skip to main content. Log in or Register to access your account.

This variation of the speaker's impedance can be seen on the speaker's spec sheet impedance curve. This is why the spec sheet indicates this speaker to have an 8 ohm "nominal impedance.
Most of the speakers are available in alternative ohm ratings usually 4, 8 an 16 ohm versions. This variety allows for more flexibility in matching the overall equivalent impedance of your speaker s to the output impedance of the amplifier.
It is important that the output impedance of your amplifier matches the overall equivalent impedance of your speaker s for maximum power transfer and so that you do not damage the amplifier. In example 1, we have a 50W amp with an 8 ohm output impedance. It has been matched to one 8 ohm speaker. Since there is only one speaker, it could experience the entire 50W from the amplifier.
But close to 3dB is easily and regularly achieved and measured for infrasonic frequencies in a small acousticly coupled link cavity: Join the cables from both speakers to the cable from the amplifier Series: Connecting in parallel normally increases the output power, while a series connection normally decreases the power output of an amplifier. I don't recall the connections used. In this case we recommend choosing an 8 ohm speaker with a rated power of at least W.
In example 2, we have a 50W amp with an 8 ohm output impedance. It has been matched to two 4 speakers wired in series. In example 3, we have a 50W amp with an 8 ohm output impedance. It has been matched to two 16 ohm speakers wired in parallel.
In example 4, we have a 50W amp with an 8 ohm output impedance. Kurt began playing guitar at the age of nine in Kalamazoo, Michigan. He is a guitar DIY'er and tube amplifier designer who enjoys helping other musicians along in the endless pursuit of tone. Prefer browsing the desktop version?
