Unusual Driver

Never seen one like this before:



Closed back 8" cone?

Model: Celestion Truvox 0818MR

I would imagine that's a high power midrange driver. I have some like that.

Here's another less unusual one:



Again another Celestion driver and a precursor to the Volt Radial Chassis. Funny how Volt claimed they innovated that when in reality they just copied and badged it up as something else.

I would say that's more unusual, not less unusual... Unless you're kidding.

Interesting how it's constructed. It appears that the motor structure is attached by its own pole piece through a concentric set of arms over the face of the cone.

I've seen it done before with the Volt Radial series:



So it didn't really strike me as unusual. The other I hadn't seen, so its all relative I guess.

Yes, the basket is moved to the front of the cone and also acts as a large heatsink since its coupled to the pole piece.
