Can you put an 8 ohm resistor in parallel with an 8 ohm speaker to make your amp think there is a 4 ohm speaker conected and if so will it change the sound or frequency?

Why should an amplifier think it is better to have a heavier load? Use the 8 ohm speaker. If your amp has a 4-ohm output you can strap a pair of 8-ohm speakers in parallel across it to match impedances. When impedance is matched to the amp, maximum power transfer happens. A mismatch doesn't let maximum power get transferred. The sound of speakers that are matched in impedance with the amp will be the same as the sound of mismatched speakers at low power. At high power (high volume), you can end up with some problems.
Talk to your local audio guy and get up to speed. Take a couple of cold drinks into the store when things are not busy, hook up the audio person with a beverage, and then open your ears and pay attention. You'll learn a lot.

∙ 14y agoWhen you put a 8 ohm resistor in parallel to a 4 ohm speaker, your amp will think there is a 2.67 ohm load. 8 ohms parall to 4 ohms = 2.67 ohms.

Can resistance be added to speakers to make a 4 ohm speaker have an 8 ohm load?
You "can" add a four ohm resistor in series with a four ohm speaker, and make it look like an eight ohm speaker, however, the frequency response will not be the same. It is better to use to correct speaker for the amplifier, or use two four ohm speakers in parallel. That resistors power rating must exceed the rating of the speaker. Half the from the amplifier will go to the speaker, while half will go to the resistor, making it get quite hot.
What is speaker frequency range?
Speaker frequency range or response is the range of frequencies that a speaker can play back sound in with a good amount of gain.
A large speaker is better than a small speaker for producing sounds with?
low frequency
How do you change the out put frequency between two speakers that is to have one speaker at 300herzt and the other at 306 herzt?
Frequency correlates to pitch, so the way to have a speaker output a certain frequency is to send a signal of that frequency to the speaker. If you want two speakers to output different frequencies, you really need two signals.
Can you connect a 8 ohm speaker for a amp designed for a 4 ohm load?
You can, but the available power will only be about half of rated, and the frequency response will be slightly different. Better would be to connect two 8 ohm speakers in parallel, making an equivalent 4 ohm speaker.
How do you make a 16 ohm speaker 8 ohm?
You cannot make a 16 ohm speaker into an 8 ohm speaker. You would need to replace the voice coil. You can, however, put two 16 ohm speakers in parallel, and the equivalent impedance would be 8 ohms. The only remaining issue is frequency response, and that's a factor of speaker and enclosure design, so best is to use the exact speaker as originally designed.
How does an electro magnet work in a speaker?
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
What is the difference between a two way and three way speaker?
A two-way speaker has two speaker cones built into one speaker assembly: one cone to generate lower-frequency sounds and one cone to generate higher-frequency sounds. The low-range speaker cone is larger, the high-range cone is smaller. In car speakers, the low-range speaker cone usually occupies most of the area of the speaker, and is made from a light-weight, paper-like material, sometimes painted black, sometimes gray. A three way speaker has three speaker cones built into the assembly, an additional cone for mid-range frequency sounds.
If a loud speaker has a frequency of 120Hz how often does it vibrate?
Time (seconds) = 1/Frequency (Hz) = 1/120 = 0.00834 seconds.
Where is the '97 Dodge Dakota Fuse Box?
if im not mistaken, the fuse box is on the on the driver side...just about parallel to where the door speaker is. if im not mistaken, the fuse box is on the on the driver side...just about parallel to where the door speaker is.
Why are pitch and frequency similar to loudness and intensity?
sound has properties of loudness and pitch. The loudness of a sound depends on the amplitude of vibration. A speaker making a loud sound moves back and forth more than a speaker making a soft sound. The pitch of a sound depends on the frequency of vibration. A speaker making a high pitched sound like a siren vibrates with a higher frequency than the same speaker making a low pitched sound like thunder
Can you produce ultrasound from a speaker by passing high frequency a.c. current through it?
Because at very high frequencies, the inductive effect of loud speaker coil is so high that practically no current passes through it. Further, the diaphragm of the loud speaker cannot respond for such high frequency. Hence ultrasonic waves cannot be produced using loud speaker.
