Sound Quality Comparison- 2 ohm DVC vs 4 ohm DVC

[ljb211087 10+ year member]

I have an interesting question. If you were to get two identical subs but with different voice coil arrangements (one with 4 ohm DVC and one with 2 ohm DVC) would there be any noticeable sound quality differences? Would the 4 ohm sub have more coils to achieve a higher resistance whist providing a stronger magnetic field thus increasing sensitivity and response? Maybe they have the same amount of coils, but maybe the 2 ohm is thicker allowing more current to flow? What do you guys reckon?

You won't notice any sound quality difference, it is just for wiring purposes.

what you laughing at? It's a completely valid question

what you laughing at? It's a completely valid question

not if you actually know anything about speakers... lol

 

[alphakenny1 10+ year member]

no its not a valid question, not hating its just the truth.

 

[Defconx3 10+ year member]

Yes, 16 ohm speakers = teh win

longer wire = higher resistance = more weight, does that change anything

I think that is what he is trying to ask.

 

[Black_Jesus 10+ year member]

doesnt mean anything moe, assuming everything else is equal, power, etc the speaker will sound the same

Obviously you don't know a lot about electronics and/or physics. My question is a lower resistance can be achieved by:

- More coils (longer wire)

- Thinner wire (Lower cross sectional area impedes current)

But if more coils are utilised, the magnetic flux is increased, which i believe would give you greater sound

In contrast, a lower resistance could be achieved by

- Fewer coils (shorter wire)

- Thicker wire (Higher cross sectional area thus lower resistance)

But fewer coils would be less efficient, instead of flux you would would really be creating more heat. I could be wrong, but surely the method of achieving higher or lower coil resistances would have an impact on the sound quality.

I realise certain people aren't technical and are trying to give simple explanations, but i want a technical explanation, i know different coil arrangements make wiring easier for certain systems!!!

the reason that question was funny becuz your question was contradciting itself. you asked if the higher-ohm coils have a higher resistance (and yes they, do obviously) whilst providing a stronger magnetic field, increasing sensitivity and response. the funny thing is the more resistance u have the less current and voltage u get. the less current and voltage you have the less magnetic field there is. the more current that runs through a coil the stronger the magnetic field around that coil will be. so how can u ask if there is a stronger magnetic field if theres more resistance. maybe if u asked if 2-ohm voice coil would yield a a stronger magnetic field BECAUSE IT HAS LESS RESISTANCE then maybe i wouldve found it to be a valid question. but its ok were all here to learn not trying to bash i just thought it was funny when i read it.

and voice coils are a way of regulating the power the sub(s) gets. for instance if your sub is rated 500 watts RMS and u have an amp that puts out 1000 watts RMS at 1 OHM.. you would want to run that sub in 2 ohms if possible.. ya understand?

just to add something to this thread, everyone knows that DVC subs sound a lot better and handle more power than SVC. Gosh everyone knows that. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif :crazy: //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif//content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif :naughty: //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif :crazy:

Ok, not sure if everyone understands, for the last time i realise about the benefits of wiring options, so stop explaining that, i know!! Ok here's an example. If i had a 10cm long wire wrapped into one single loop vs a 50cm long wire wrapped into 10 loops, which one would produce the bigger field? I think you will find that in the first scenario (with lower resistance and fewer loops) that the magnetic field will be weaker as there are fewer loops, most of the current will be converted to heat. In the second scenario, the more loops the higher the resistance yet the stronger the field. Does this mean a 4 ohm system is more efficient?

Does:

More Loops = Stronger magnetic field = Longer wire = More resistance?

OR

More Loops = Stronger magnetic field = Longer wire = Lower resistance by some sort of strange effect

Just thought of another example

Have you ever taken windings off an electric motor? You will find that originally the motor will spin fairly fast with high torque, when you take off more of the windings you will find that the motor spins faster with very little torque but it will draw heaps more current. THIS IS WHAT I"M TRYING TO GET ACCROSS

Correct me if i am wrong, but why does high end home theatre equipment have higher impedances?

And check this out

Stetron then tried replacing the speaker with a higher impedance speaker (50 ohms instead of the original 8 ohms) and the results were stunning. It reported the toy's sound was much louder, clearer and less harsh. Objective audio lab tests later bore out those results with a markedly flatter frequency response, better low frequency response and more output capacity

It is my understanding that as you decrease the load on the amp it makes more wattage, but you lose it's ability to use some of that power to control the woofer's travel (damping factor). Now whether or not there is an audible difference I can't really say. That's my $0.02
