we also have to consider the extremely low price of the lab 12. for that it gets applause. I've no doubt that an order of 50 with whatever changes we see fit will end up costin more per each driver than the retail price of the lab12 currently.

I totally agree with you on that.
An upgradation to a newer 3" coil will also cost more.

But there certainly are cheapo drivers out there with much bigger gaps (typically Chinese) that make Eminence look like precision machines. It can get worse. And of course it can get better - that's why you pay $400-600 for a driver.

I haven't had a lot of Eminence failures. I've had them so hot you can smell it 10 feet away without failure, but by then they're 10dB down. If you did THAT with a tight tolerance gap you'd be scraping the coil against the pole piece and have a ruined driver.

If you want an upgrade switch to the Ciare 12.00SW that has a 4" voice coil. Of course the T/S on the Ciare are totally different than a Lab12, but so would be a 3" voice coil Lab12.

That's not what we're talking about here. My PAL12 has the magnet directly exposed to ambient air. That's not the issue.

Exactly. We would be targeting the driver that is in the Danley cabinets. He is using custom eminence 12" drivers, cone appears the same as well as basket. But with a 3" motor.

This is the whole reason I brought this up in another thread.

Why else would you need a larger voice coil - for heavily loaded designs that are low excursion and have poor cooling, like the lab-sub? Most modern designs have good woofer cooling.

Power compression happens even on a design with great cooling and a large VC. You just want to minimize it.
More surface area will be a good thing; hence the desire for a good small driver such as the LAB12 with a larger VC.

Danley saw a need to upgrade from the factory lab 12. I figured if there was enough interest here we could get a group buy and benefit from this. I figure at around $200 the 3" LAB12 wouldn't be a bad deal at all.

There's also the b&c with a huge voice coil used in the TH-mini (12tbx100...4" VC) This would just be another option at a good price.

I dunno, but there's something about those big-coil subs that makes them sound different, in a better way. The old 1200GTi for example, also equipped with a 4" coil, remains one of my favourite subwoofer drivers.
