What does 4/8 ohms impedance means? Does it mean that they are dual impedance and can be use on cars and home systems? What is the distance between

I not to sure, but I believe that the lower the ohms more voltage it uses and it plays louder

The impedance of the speaker doesnt change in Bridged or Parallel or Series modes.The important thing is what is being presesnted to the amplifier.The speaker manufacturer here is saying that these speakers will suit amps that require any load between 4 and 8 Ohms....I've used these speakers in my car and would see no issue in a home...I don't know the distance

Not sure, I suppose they mean that they can be used in stereos that require 4 or 8 ohm resistance speakers. I used them on my stereo cabinet speakers in conjunction with the Pyramid 300 watt woofers. My cabinet speakers (originally Altec Lansing) had a two way speaker system frequency adjuster, & I had to turn it way down because these little tweeters put out so much sound. They really produce great sound together and am very pleased with them. The distance between the mounting holes is just over 2-1/4" which I had to modify for both the tweeters & woofers (not a big deal). Hope this helps.

It has a power adapter to drive headphones. As far as ohms I believe I saw 80ohms as the headphone impedance.

Hi,We have both. The one you are looking at is 8 ohm. Thanks for asking and have a nice day.

Well this subwoofers are 4 ohms , and your average home audio systems are 8 ohms so I won't recommended for home audio.

FYI - Impedance matching is the resistive value measured in Ohms. For instance, most speakers have an impedance value of either 4 or 8 Ohms. Headphones can have an impedance value of up to 600 Ohms. Improper impedance mismatching can cause anything from poor quality sound to irreversible equipment damage/failure. Experiment at your own risk or get help from a friend that understands these electronic principles.

True Four Ohm Impedance technology: speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load. It will be very hard to find a 2-ohm system. Almost all 4" are 4-ohm.

Sorry! This question exceeds my pay grade. I've always used only 4 ohm, only 8 ohm or switchable 4 to 8 ohm speakers together.

as I understand the higher the ohm the less efficient they are. I would suggest you call a reputable stereo store in your area for best answer. I put mine in a stock system and they work fine.

My understanding is 2 OHM is better. I would however recommend you install the amp to get the proper sound that the speakers are capable of. I have not done this but I need to.

I would expect that if your speakers are more than 4 ohms when connected you'll be fine. It really doesn't matter what your speakers are rated only their impedance usually 4 to 8 ohms.

Most headphones used with portable electronics are low impedance, around 32 ohms. The lower ohms make it easier for the amp to drive them. Headphones range in impedance from 16 ohms to 600 ohms. There can be some significant advantages to higher impedance headphones. A higher impedance allows for more turns of wire to be used in the voice coil of the driver. This can result in a better "motor system" with fewer compromises resulting in better overall sound. Higher impedance headphones also require less current to drive and that typically reduces distortion in multiple ways. The amplifiers driving headphone nearly always produce lower distortion into higher impedances. The difference between 24 ohm and 32 ohm is quite negligible. The "24 ohm" is somewhat of an odd number in terms of ohms as typically, you will find 16 and then 32. You shouldn't have any problem using the 24 ohm but you will likely get a better response from headphones rated at higher ohms. You don't state the type of headphones. If you have headphones designed for portable consumer use that have an impedance of 80 ohms or less, it's very likely the manufacture designed them to be driven directly from a typical device like an iPod. Using an amp or DAC with such headphones usually won't improve their sound much, and might even make them sound worse or create other problems like excess noise and channel balance issues. This is especially true if your headphones already get loud enough for your tastes. Generally, 16 - 32 ohm headphones with a sensitivity rating of at least 100 dB/mW do not need an amplifier.

A speakers impedance is quite variable across the frequency band. So the 6 ohm speaker is just an average and there is no standard in assigning this nominal rating. I have used 8 and 4 ohm speakers on either taps and frankly can hear or detect no difference. But, to be safe you can just hook the 6 ohm speakers to the 4 ohm if you are worried. It will be fine either way.

This is a dual coil sub so I'm assuming it is 2 ohms if you run the two coils in parallel and 8 ohms each side. This doesn't quite work out, you're right, as it should be two 4 ohm coils (which is how I see it described on sites that sell it) that in parallel is 2 ohms or in series is 8 ohms. I built my own box to the sealed box specs (remarkably small) and am driving it in stereo (though my head unit has a dedicated sub setting for outputs which may sum to mono on its own) with a 1000watt stereo amp and I assumed it was 4ohm per side. It sounds amazing in my little car, as a matter of a fact it took me forever to get the sub balanced with the rest of the system because it is amazingly efficient so I kept turning down the sub out as well as the amp trim and finally settled on running it with a 150hz cutoff instead of 75hz. Hope this helps.

What matters is the impedance. Most Amps are 8 ohm as are speakers. When you hook multiple speakers in parallel the impedance goes down. The selector ensures that the impedance is at least 4 ohms even when as many as eight speakers are hooked in parallel (and would otherwise present 1 ohm of impedance). On my Yamaha receiver there is a switch that allows for a 4 ohm load and that is the key. You can probably run a 4 ohm load from an 8 ohm driver, it just means that more energy is dissipated in the amp than in the speakers but hopefully not so much as to do damage

True Four Ohm Impedance technology: speaker's 2-ohm impedance combines with speaker wire impedance for a 4-ohm load.Awesome speakers in my opinion. I had an 840 watt 4 channel cheap brand amp pushing them and they sound amazing. The tweeter attenuation is a nice feature too.

Are these home audio or auto speakers? ... Yes... These are good for both home and car. At 8 ohms a car stereo amp might not play them as loud as a 4 ohm speaker but it will not hurt the amp. If you're concerned about getting 4 ohms at your amp just wire a pair of 8 ohm speakers in parallel. Usually the only difference in home and car speakers is the label, although better car speakers may be built with materials that hold up to temperature extremes better than most home speakers. I personally use home and car speakers interchangeably because any good amp will have no trouble running a 4 ohm load.

These speakers are 4 ohms impedance. You can go to www.crutchfield.com and search SPS 610 and go to features and specs and all the info is there. I wouldn't suggest buying anything from crutchfield because they are expensive but they are great for finding out product specs
