If I remember, they have multiple coils, like the earlier tc sounds.
That way you don't have a really long coil that can char the ends, or the coil not hanging in the magnet.

I'd heard a few of the 8's.
They went deep, but had no output in my mind.
But the box was small compared to a velodyne or definitive anyway.

I'd rather have multiple larger drivers barely moving (less distortion) than a small driver really flying back and forth. As you double the drivers, for the same volume excursion is halved, and distortion drops to 1/4.

Yea Norman It was a literal impulse buy. Found then in the last 6 minutes and they seemed cheap. And All so for a completely different approach. I have for the last 8 years been buying Richard Allan cg10's and a few 12's and a pair of cg10t's and 8t's.

But the cg10's I have been collecting for a array.I have lost count to be honest but I think I have 8 or maybe as many as 12. Ever body says I cant do any tapped horn but thought maybe I could do a tapped horn in push pull with the 10 or the 12's. I do have 4 of the 12's. They are lovely drivers for what they sell for used. But you do get a few duds off ebay I find. Here are some specs.

Any potential here? I have the cg12 supers and normals.So maybe I have 6 12's

cg10's look fine for a TH.
I'm not so sure on the ultralow cg12's Qts.
Rear or front horn only for those, maybe a scoop.

If you run the numbers, they'd not have anything below 100hz in a sealed or ported.

cg10 it is. I have the most of them.I can imagine the specs will be all over the place depending on the condition of spiders and surrounds. Thanks Norman

np, just my opinion.

has anyone measured the sunfire woofer specs ?

I'm betting they are 16ohms or higher.

xmax is also a limiter.
