is 4 ohm better than 8?
316877
4 Ohm Vs. 8 Ohm. A 4-ohm speaker requires more power from an amplifier than an 8-ohm speaker to produce the same loudness of sound. This is due to the relationship between voltage, current and resistance in electronic circuits; for a given voltage, a lower impedance means a greater current.

Therefore, 1/4 is greater than 1/8 and the answer to the question "Is 1/4 greater than 1/8?" is yes. Note: When comparing fractions such as 1/4 and 1/8, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.

1 Ohm stable is fairly meaningless, unless you're going to complete in the Car Audio SPL (sound pressure level - ie volume) contests. Its completely irrelevant. ... The only reason they call it “1 ohm stable” is so they can quote 1200W as the peak output.

Short answer: The ohm is the unit of measure for impedance, which is the property of a speaker that restricts the flow of electrical current through it. Typical speakers have impedance ratings of 4 ohms, 8 ohms or 16 ohms.

As MM cartridges have a higher output, they also have a higher impedance of 47,000 Ohms. In contrast, MC cartridges at lower outputs, have a lower impedance at 100 Ohms. For the capacitance, you'll find MM preamps with up to 100 pF while MC preamps have about 3000 pF.

Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of 2.66ohms. If the speakers do not have a common impedance, you can use formula 1 for two speakers or formula 2 for more than two speakers.

Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass. On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass. Thus, make your choice depending on the kind of bass you want.

Fancy coils are only better to a point. If you buy them and they cost about the same, then sure why not, but if you make them yourself then anything above a triple core fused Clapton is not worth the extra work imo.

0.625 is greater than 0.25. Therefore, 5/8 is greater than 1/4 and the answer to the question "Is 5/8 greater than 1/4?" is yes. Note: When comparing fractions such as 5/8 and 1/4, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.

A thicker wire simply has more 'lanes' on the go at once. A higher current for a given voltage means a lower resistance. The thicker wire in (4) has a lower resistance than the thinner wire in (3). The resistance of a wire decreases with increasing thickness.

Powerbass makes a pretty decent amp. Those 14.4v ratings look pretty accurate, but don't expect under-rated numbers or to see that power at 12.8 volts.

AMPS is amount of electricity. VOLTS is the Push, not the amount. OHMS slows the flow.

Set the dial on the multi-meter to lowest ohms. Touch the multi-meter probes to the screws on the face of the element A 3500 watt element should read around 16 ohms a 4500 watt element should read about 12 to 13 ohms a 5500 watt element should read between 10 or 11 ohms.

The lower the impedance, the more efficiently it allows the electric signal, which is basically the music, to pass through the speaker. Most speakers are rated at 4, 6 or 8 ohms, and cheaper receivers can sometime have issues driving low-impedance (namely 4 ohm) speakers.

Generally home audio uses 8ohm speakers and car audio uses 4 ohms or 2ohms. Most likely you car audio head unit or amplifier is going to be designed for 4 ohm speakers, but its OK to use an 8 ohm speaker on them. But 8 ohm speakers on a 4 ohm system only need to be rated at half the output power of the amp.

Microohms. One microohm is equal to 1/1,000,000 of an ohm, which is the resistance between two points of a conductor with one ampere of current at one volt. The microohm is a multiple of the ohm, which is the SI derived unit for electrical resistance.

Apple earbuds are 23 ohms... my fave studio headphones, Audio-Technica ATH-M50s, are 38 ohms... one of the most common studio headphones, Sony MDR7506, are 63 ohms. So, more "pro" headphones are higher impedance, but that just means that you will get less power (lower volume) on a low-voltage audio source.
