Greetings all sifus,what's the different between a SVC subwoofer and a DVC subwoofer apart from the voice coil??
Does the sound from DVC is more powerful than SVC?? rclxub.gif

Can't say DVC is more powerful than SVC!
depend how u tune it only...

DVC provides more wiring option wink.gif

yes

if ur amp is strong,you can wire it to 4 ,2 ,1 or even 0.5 ohm

technically speaking DVC should be more powerful because it has 2 voice coil.. and thus more electricity pass through and more movement.

That said, u will need more power to drive it and depend on how u wire it, it can be harder to drive.

Do NOT expect to get double the power or beating 2x SVC.

technically speaking if u want more power... but don't want to have 2 woofers, DVC is the way to go...

Yea, more wiring options for your amplifier. In no way a DVC is better sounding, louder or more changgih than a SVC. smile.gif


Added on October 10, 2007, 12:37 amIt's also not true that a DVC is harder to drive than a SVC. Very much depends on the power handling and sensitivity ratings of the subwoofer. I've had and seen many SVCs that are harder to drive than DVCs.

So, why DVC? ...

Answer:

Wiring options.
I.e A dual 2 ohm voice coil subwoofer can be wired to 4 ohms or 1 ohm. A dual 4 ohm voice coil subwoofer can be wired to 8 ohms or 2 ohms. Say, you want to install 2 subwoofers or more. Using a couple of DVC subs is easier to configure to accommodate or squeeze the most of the amplifier.

DVC @ 1 ohm easier to drive or SVC @ 2ohm ? technical comparison 1 ohm is easier to drive than 2 ohm ? I don't think so.

Of course if u were to wire it 4 ohm it easier to drive at an expense that you will get lesser power.

i have seen alot of cases where amp shutdown when it's wired at 1 ohm. some entry level amp doesn't even take 1 ohm.

Hur??? rclxub.gif doh.gif Why would someone run a sub @ 1 ohm or 2 ohm off an amplifier that minimum impedence for bridged mono is 4 ohm stable? Plain dumb. You'll need dedicated monoblock (that is 1ohm or 2ohm stable) or a purposed high-current amplifier for that purpose.

But I can kind of guess where you're coming from. You're basically saying that an amplifier is less efficient and stressed at lower impedence. However, think about this... running loads not recommended in the specifications is a no-no in the first place. It damages your equipment or kills it.

Very simple actually. RTFM.

i thought lower impedance will stress the amp more? hmm.gif

drool.gif tell me more about it...
i dun think DVC has anything to do with more power output either... a 12" 300W rms DVC 4+4 or 2+2 and a 12" 300w rms SVC sub are still a 300 W rms sub... nothing more...

also for more power output... you change the amp and also upgrade the sub and also the box if needed... that would give more power and feel...

this is interesting... then tell me whether wiring a 4 Ohm DVC @ 8ohm draw more power or 2ohm ?

given 2 amps
1) 12" 4ohm DVC (wired at 2 ohm)
2) 12" 4ohm SVC

which one will draw more power ? if your amp is capable of outputing 300w@4ohm and 600w@2ohm

if you scope your amp, i'm sure you know the answer

drool.gif drool.gif drool.gif

p/s: some ppl just see 300w being much superior than 600w... of course not the resistant... if they take that into account, it doesn't matter... and technically speaking... 600w does indeed look much more impressive than 300w...but down to the SPL and SQ it doesn't matter smile.gif

bro definitely an amp which is capable of driving low amp which i am talking about, wat's the point of putting a 'not in the spec' amp, sure blow up lor icon_idea.gif

just an example http://www.lightningaudio.com/products/pro...en_US&p_status=

Lightning Audio Strike Amplifiers : S4.1000.1D
Rated Power 250 Watts x 1 @ 4-Ohms
500 Watts x 1 @ 2-Ohms
1000 Watts x 1 @ 1-Ohm

so you are all along talking about the amp... then why about the sub in the first place?

and i think you need some tutorials on DVC subs...

a DVC sub at 300 w RMS analogically means 150Wrms/voice coil.... so 2xVC= 300 W rms... not 300w rms /voice coil

so where does the 600 w rms of a rated 300 w rms DVC sub come from?

the amp... if you feed it 600 w rms... the sub is still 300 w... but receiving 600w.. so you are sort of abusing it for a higher SPL or a better SQ... but then you are ricking buring the VC...

we scope amps a lot but to find out which has more power... a multimeter with AC option is enough... for your info...

as for the amp suggested... at least you know how to read the manuals... why not read up some tutorials in the net about DVC?

my guess is you actually take a 12"300w rms DVC sub as 600Wrms sub... or you are jus wan to say tht amps are putting more power at lower ohm than the higher ones thus harder to put out the power...

cheers...
