AnswersDrive4-ohm Speakers Should Typically Be Mated with Higher Power Amplifiers. Most bookshelf and tower speakers are rated either 6-ohms or 8-ohms. Any speaker impedance rating that is 4-ohms is typically going to be a high-end, audiophile product that wants an amplifier that can really put out some power.
Correspondingly, what is the meaning of speaker impedance?
A lower impedance speaker will accept more power. For example, a 4 ohm speaker will extract more power from your amplifier than a 8 ohm speaker, about twice as much. The problem most people have with speaker impedances is how to combine speakers safely without blowing the amplifier or speakers.
Is 2ohm or 4ohm better?
Subwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. A DVC 4-ohm sub can be wired into a system as a 2-ohm or as an 8-ohm load. A DVC 2-ohm sub can have a total impedance of 1 ohm or 4 ohms.
How many ohms are car stereo speakers?
Home equipment is designed for high voltage, low current output. Most car audio equipment is designed to operate into lower impedance loads (4 ohms or less). Amplifiers: As you know, it is possible to produce more than the 45 watts peak power (22.5 watts RMS) into a 4 ohm speaker in a vehicle.
