I have heard a lot of great things about these so I am planning on getting these for my explorer. I was looking around on ebay and noticed some are dual voice coil and the cheaper ones are single voice coil...What is the difference and is it a noticeable one?
The difference is only one of wiring options.
Some people mistakenly believe BS Best Buy product literature about DVC woofers being "two-subs-in-one" which is why, at a retail level, they can command the extra $10 or $20. Of course, to be fair, the DVC prolly takes the extra 2 cents to make as well, if just for extra plugs. Not really sure why it would make a difference on ebay.
You should buy from a real store. Even have that.. eh.. how you say.. warranty?

$305.70 for a pair shipped.
BTW, those really are *outstanding* woofers.

Sedate: ISn't twice the amount of coil in the gap as a SVC version? Or do they just cut the length of coil in the gap in half to accomadate the second VC?

If you had two subs that were otherwise identical.. I couldn't imagine so. That would change power handling, tonality.. I mean.. the entire speaker would be different. I mean.. wouldn't it have to be?

From this link:
Naturally, it is more expensive to wind and terminate dual voice coils and you will typically pay a small premium compared to a similar single voice coil speaker. So what do you get for the extra few bucks? Do dual voice coils offer a performance advantage? Not really.

From the first line of this link:
The primary advantage of the dual voice coil speaker is wiring flexibility.

Yea.. you get a different dcr or whatever the ts parameter for impedence is (?)... but if you graph a DVC and SVC next to each other with like WinISD.. they always right much the same to me.
