go single
you dont really need a voice coil for subs. I mean it all depends on what you want cause they cost the same. But IMO i would rather let my highs and mids take care of all the voice and let the subs hold the bass. I feel you'll get a better sound from them. thats just me. I had a switch on my amp to turn on and off the vocals on the sub and I think it sounds better with them off.

ummm? we don't need a voice coil for subs? Voice coils are what drive the speakers... I think you're confused there buddy.

Dual Voice coils means two separate voice coils for the speaker..

Read this

 

I have a 12" Audiobahn sub with dual voice coils. I like it a lot. I'd say go with two? ;x

 

dual voice coils subs will pound harder than the single voice coil(in comparision to the same level subs)...

i believe that the daul voice coil are able to take more watts than a single.

if you look and have done a search... most comp. subs are all dual voice coils.

 

dual voice coils offer nothing over single except versatility.

dual voice coils allow you to wire them differently, allowing a 2 or 8 ohm load.
single voice coils only allow you to wire them in a 4 ohm load.
this is assuming each voice coil has a 4 ohm impedence.

EDIT
have you searched/ svc vs dvc thread

 

yeah the question shouldnt be which is better svc or dvc. they both are the same, its just the matter of what kind of ohm load they are compatible with. Check your amp and see what the stable ohm is and then buy your subs with that information. svc just gives you less options when wiring the sub up and dvc gives you more options on what ohm to wire it up on. svc or dvc wont have a sound difference just wiring is different

 

I dont know much about it but i have a 12" alpine type r and its dual voice coil and it sounds great. dont know how a single would sound.

i somewhat hate my hefty dvc type s...but i hate it because it's a 12"....i wanna downgrade to a 10"!!

why would you wanna do that...? i thought 12 > 10 lol

 

from what i understand, if you want a tight sound, with fast response.. go dual.

it is also my understanding that it achieves this because a dvc sub controls both the in and out movement of the speaker.. (is this correct?)

I have an infinity perfect 10 in a small sealed box, and would love to upgrade to a DVC for even tighter and faster response.

 

why would you wanna do that...? i thought 12 > 10 lol

10s are optimal for sound QUALITY, because of their fast response capabilities. 12s are a little slow, but are great for loud boomy bass...

if you listen to actual music with instruments, IE not synthesized.. you probably want 10s

 

this should be quick and easy now, im looking at some infinity 10.1 perfects and they come in single and dual voice coils.......which is better? I am new to the scene and i have heard nothing but good things about them. They are the same price so im wondering what the difference is, pros and cons. thanks for the help.

Fisrt you need to know how many subs you are going to run. Then you need to know what amp and how much power your going to run. then you can make up your mind on svc or dvc, post the information on this and you can get a solid answer. There is to many factor to answer your question. Just alot of diffrent setup possabilites. hope this helps! peace

 

The main thing is to match up the correct ohm rating with your amp. Example... You dont want a 2ohm svc sub, if you have a 2ch 4ohm steady amp. It will cause your amp to heat up and constently go into protection and shut off. Another example is you dont want a svc 4ohm sub if you have a 2ohm monoblock amp, Your amp will only be running half as efficienlty as it should (400w rms 2ohm amp + 4ohm sub= 200w to sub)

 

I think you people are forgetting to mention the versitility that being able to run at 2 ohms offers There is a major difference between running at 2 ohms and 4 or 8 .

200 watts @ 4 ohms = 400 watts @ 2 ohms.

If your amp can run stable at two ohms then get the dual voice coil. It will be a lot louder. For those of you who dont believe me and have a dual coil; disconect one of the coils so that the sub is only using one coil(just like a single coil speaker) or connect both coils in series if your amp is 8 ohms compatable.

dual coil is can be a major advantage depending on what ohms you want to run.

Aaron, depending on how many ohms your amp can go (the lower the better) you could...

say the amp is 100 watts at one ohm.

at 1 ohm. watts=100 total
-run two dual coil subs all in one 4-way parallel circuit.
-each coil will get: 25 watts
at 2 ohms. watts=50 total
-run two single coil subs in a paralllel circuit.
-each coil will get: 25 watts
-run one dual coil sub in a parallel circuit.
-each coil will get: 25 watts
at 4 ohms. watts=25 total
-run one single coil sub.
-the coil will get: 25 watts
-run two dual coils with each one in it's own little parallel circuit and both of them wired together in a series circuit.
-each coil will get: 12.5 watts
-at 8 ohms. watts =12.5 total
-run 2 single coil subs in a series circuit.
-each coil will get: 6.125 watts
-run one dual coil sub in a series with itself.
-each coil will get: 6.125 watts

Sorry for the rant, I am bored.
If you want one sub you should get dual coil. you can run that one sub at 2 ohms,4 ohms or 8 ohms.
If you want two subs, you could get single coils or dual coils.

ohh and those of you who also will argue that as resistence (ohms) decreases, flow (watts) increases linearly, look it up. some amps just suck and say 200 watts @ 4 ohms and 350 @ 2 ohms. They are not efficient at 2 ohms and you should get one that is.(unless you don't care about having double the watts)
look at my crappy $80 amp for example. it is a BOSS riot 850 and it overheats after being pushed for more than a couple hours. but it makes 200 rms watts at 4 ohms and 400 rms watts at 2 ohms.
hope that helps.

 

mugendc2 you beat me to the ohm thing. thats what I get for ranting.

i need bass in my life but not thatttt much bass. besides the 10's seemt to hit cleaner but not as deep as a 12. I need the smaller space + a 10" that can fit in my qlogic box will allow to fit underneath my rear strut bar.

I love my strut bar because i dunno about u guys...after installling that rear type r strut bar i felt a difference. could be the in teh head but somehow i feel the difference.

no, no, and no.
tight sound, fast response..you should be looking into a good speaker composition and enclosure. [plus other factors, but svc vs dvc has nothing to do with them]
in and out movement..enclosure.

as said before
the only difference between SVC and DVC is versatility.


that is all. stop this nonsense

2 is not always > 1 in this case..

 

I looked around on crutchfield and i came up on this. If your on a budget get this amp, it will work with 2 10's that are 4 ohm svc. profile ap1000m I didn't check to see if it was a class d but it puts out 500 rms at 2 ohm at 14.4 volts, that will def have you bumping, If you can afford it I recommend the mtx 3401 class d it puts out 400watts at 2 ohms. but it actulaly puts out about 425 at 2 ohm at 14.4 voltswith no heating problems. which means half of your power that your amps put out is wasted into heat. cool amp more power, hot amp less power. or you can get the same name brand amps and subs the infinity ref 611a class d will do the job 657 watts at a 2 ohm load at 14.4 volts. at the price of 349.00 , there you go ! good luck. fixed.

peak power ratings. those are not rms.

did you notices it says rms at 2 ohm and not peak, I am not bashing but quoting what the manfan says, I can vouch for mtx because I am a dealer for them and i go to there seminars every other months wich they requirer, I cant speak on the infinity because i dont sell them. but it will still push thoses speakers no problem, you do not need to run a speaker to its full rms to benifet its potential. but it helps. alot of people thing that running a sub to it peak is good. its not, peak is a short busrst of music for a sec that the speaker can handel with out burning up. I hope this clarifies anything that I have posted. Desmon . I was going to post this but before i put my foot in my mouth I checked with a shop out here that is a dealer for them" comp soundworks" in bellflower ca, and they said the 611a amp would be fine.

Im using the profile ap1000m to run my alpine type r and it sounds real good no problems so far so i guess i can vouch for it. it does put out 500 RMS at 2ohm, 1000 peak. and it only cost me $115. perfect low budget amp

 

dude
ive had both single and dual in six pairs of different subs. and if you can get them for the same price then dual all the way more power handling just my 2 cents

 

Wow, if you guys dont know what your talking about, please dont comment. Lots of misinformation flowing around. Just read what Cell21633 said.

oops..missed that on the very first page. i skipped ahead to the features tab.
i stand corrected.

I am not sure what your trying to say. I do know what I am talking about, I run my own shop, I have been in the industry since I was 16,I am now 27. I paid my dues, I would never give anyone false information. If I don't know something i will find out before I make any post. Just like i did in the post before this. I called a shop that I am friends with that deals with infen. I am mecp certified installer and so are all of my employee's, some people may say that aint ****, but to me it proves that you are detacated to your work.
