HI There
i guess the topic in the question plzzzz explain the both of them and ,,,,,,, if we can hear the differnce between them
which of them is better ( SQ/SPL) if there's
thanx alot

SVC means single voice coil, there's only one input on the sub. Most of the time the SVC subs don't have as good of a power rating as DVC, not saying this is always the case or actually the way it is but I'd go with SVC for SQ.
DVC means dual voice coil, instead of 1 input, there's 2 on each side. This allows for much greater range of ohm values you can get from the speaker, just depends on how you wire it. It's more complicated to wire them but it's worth it in the end. DVC's usually have more power handling, meaning less sensitivity. These are made with heavier cones so it takes more to push them, but they get much, much louder, most of them.
If you can find subs that have a really good sensitivity, along with a pretty good power rating you should be able to get good SQ, with the right box. The lowest dB sensitivity I'd get for SQ would be 92 or more. That way they'd be louder at lower levels so you wouldn't push them as much, well maybe lol, to get the same, which would mean less distortion and greater SQ.
My subs for example are the exact opposite of that, heavy cones, low sensitivity, very low to me acutally, at 86.3 dB @ 1w/1m, higher power rating, 1000 rms, 12". They don't get as loud as easy (not talkin competition loud I mean loud as in your sitting in the car and you wanna shake things) but they shake windows on houses as I pass by, just a little bit. I haven't heard to much better of a system around where I live, we're all poor down here lol, so most people have small systems that have enough thump, and not to much, but still good enough for them.
I probably missed quite a bit, but the golds will know what I don't, one reason being half the stuff I told you I read from them.

Most of the newer subs made today, come in both SVC and DVC versions. As Monk stated, DVC's are generally less efficient and take more power to drive them to full potential.
Depends on the amp power and enclosure you choose. SQ subs are generally mid/high 80's SPL sensitivity @ 1 volt/1 meter. SPL subs are generally low efficiency, heavy motor structures and need loads of power to get them pumping. But they really pump out the bass with adequate power.
Finally, SQ performance is something we can detect well below 100dB of SPL. Once the SPL rises above 105 or more, the human ear begins to shunt the extremes and we lose accurate perception of how well mixed and balanced the system may be. It's more a proximity effect... if we get out of the car and stand back 10 feet or so and listen, than we can discern the SQ quality in the mix, as the SPL is lower due to our distance for the speakers.
Do you see the connections I am trying to point out here?
