Replacing 6 ohms Speakers

Searching for 6ohm speaker(s) to replace your existing stereo system or bookshelf speakers?

Important facts you must have with you when replacing any speaker:

• Impedance or Ohms
• Physical Size – Diameter (inches) and Depth of the speaker
• Power Rating – Wattage

Sometimes this could be a tedious and time-consuming task. Throughout our years in selling speakers we were having difficulties locating the original and/or suitable substitute 6ohms speakers. However, based on our experience and research these 6ohms speakers can be replaced by 8ohms speakers. One should always keep in mind the ideal matchup is when the speaker impedance is the same as the output rating or the manufacture’s selected rating of the unit. Please also note, the best sound can be obtained from the speakers when they have the correct impedance match. 

If you are interested in replacing your component stereo set/ home theater speakers at home, the are just a few parameters you will need to follow when choosing replacement speakers are Impedance or ohms, Power Rating, and Physical size. 

Impedance / Ohms 

It is recommended that you choose a replacement speaker that has the same impedance as the original. Using a higher impedance speaker, such as one rated at 8 ohms, will not cause damage to the stereo set unit, and using speakers of less than 6ohms impedance is not recommended unless you know exactly what you’re doing; this will overload the stereo set unit and may damage it over time, especially when run at high volume levels. Additional Info: 6 (Six)ohm speakers are less resistant than 8-ohm speakers. Thus, 6-ohm speakers will play a little louder than 8-ohm speakers. However, if the component stereo set unit is designed to play 6ohm speakers connecting 4-ohm speakers you will run the risk of damaging the component stereo set unit.

Impedance is set by the speaker manufacturer and cannot be altered. The ohm rating can be found on an identification plate located on a speaker’s back panel.

Additional Information:

Given that all other things being equal that is it produces an equal signal flow from the component stereo set unit/ amplifier, the Lower the Ohms/ Impedance rating of the speaker the greater the current flow and the greater is the Power Output or Watts. Therefore a 6ohm speaker will play louder than an 8ohm speaker given that all external components that is used to drive both these speakers are equal.

4-Ohm speakers are normally used in Car Audio applications.

6-Ohm speakers are normally used in Household appliances such as component stereo set units, home theaters, portable CD/mp3 players etc.

8-Ohm speakers are normally used in power amplifier applications such as integrated amplifiers, power amplifiers setup etc.
