If they chuckle because you shouldn't do it for reliability reasons, one of two things is happening. One, they know what they are talking about and my respect for JL Audio has plummeted. Or two, they have no idea about the technical side of speaker design, which is more likely in about 95% (probably more) of the cases.
This next statement is directly from JL in an email they sent me about this subject:
"You absolutely must hook up both voice coils on a subwoofer. If you only hook up one side of the voice coil it would be like playing only half the woofer. You will loose output capability. Hope this information helps out. Thank you."

http://www.jlaudio.com I have since sent a reply asking about the woofers warranty if only one coil is used. I will post their reply as well. As you can see JL stands behind the NO-NO for one coil on a DVC speaker being used. So if the JL tech has no clue then we are all in trouble....
So dnewma04 if you were making a speaker and had a choice between making it a single vc or dual, wouldn't you make just the dual since that according to you it is ok to use one coil? That is plain logic, why make a SVC if a DVC can have just one coil being used???????? I think the singe coil would then become extinct. Manufactures want to make money so if they could lower the cost of making woofers by eliinating the single woofer design (a DVC may cost more to produce, but now they wont have to make a svc) and just making dual coils dont you think they would?
Many manufactures do lie about specs, if you happen to have Bass Box or other well designed woofer software, when placing their "specs" it comes out totally not possilbe in some cases.(Bass Box has a way of knowing what is and what isn't possible based on tolerances) Not everyone does it, but I know of just a few manufactures off the top of my head that change specs to make their woofer more appealing. I am not saying they are drastically changing them, but I have seen the actual DUMAX sheets from DLC on several woofers and their "published" spec is not correct at all. Hifonics one time actually faxed me DLC's Dumax sheet, then I went to their site and the specs were not the same. I have no reason to lie about what I know, this is a Contour website not an audio forum were some hoser would walk in and start acting like an A** thinking he knows all. I know for sure that I am not Richard Clark and I could learn alot from others, anyone who says otherwise is just ignorant. If you think I am wrong thats fine, like I said why would I lie?
Just trying to enlighten a few souls thats all....
