Same great driver now available in 4 ohm load.
Not even compared parameters yet.

An odd duck, actually, as the standard LAB 12 is six ohms. I'm surprised they brought this out.

Squeeze out some extra sensitivity to compete with newer bass designs maybe?

It's only a 2dB difference, and that's only of value if your amp is too small to drive the 6 ohm to full output.

I have a standard 6Ohm lab in a small sealed box for the garage. 1.2cu ft sealed powered by a bash300.

I'm not very good with winISD but this C driver models less?

If you let WinISD calculate the default cab size the 4 ohm gives a smaller box size than the 6 ohm, but with a higher F3, so you're not really gaining anything.

Was checking into replecments for an older set of JL Audio subs that I use in Isobaric setup. This LAB12c looks like a really good match. I think because of the Vas.

So i guess that does make it odd compared to more modern woofers

Is this more of a woofer or subwoofer? How would it work in a mid-bass setup, or as a woofer in a 2-way of 3-way?

My interest in the 12c would be to replace old automotive subwoofers that found new life in my home theater set up. Xmax is 13mm IIRC. That would be fine for me as a subwoofer but a lot of sub now have ~18mm xmax that is preferred by others.

danley spec'd the original lab12 for the lab horn project. it also found use as a ported sub in imax installs. xmax on it is conservative in the sense that there is much more 'usable max' or whatever you want to call it than it may appear.

Listen. It's All Good.
