audioguru Posted September 21, 2006 Report Share Posted September 21, 2006 4 ohm speakers are used in cars. Home speakers are 8 ohms.An ordinary car radio provides 3.8W or 14W to a 4 ohm speaker.Compare the weight of your speakers to speakers with power ratings in stores. A more powerful speaker has a larger magnet and weighs more. Except some expensive speakers use "rare-earth" magnets that are stronger but smaller.
