I am looking for a "sub" (I forgot what they labeled it as, but I recall a "sub" but it wasn't. A transducer came to my mind when I saw it) that is a flat aluminum panel with no support on the sides from a surround or basket.
It is pretty much free floating.

The motor structure looked to have been made from cylindrical magnets and was HUGE. The magnets were vertical and in a circle.

As I recall it claimed SPL levels of 18 18" subs, and had an excursion of 24" peak to peak.

Anyone know what I am talking about?

Who makes/made it?

 

yes the adire audio's parthenon using 24 neodynium magnets....

RE audio has a similar sub known as the XMX utilizing one of hteir motors.....

And believe me, yes they are subs...very very badass ones btw the cone is actually meant to fit in a perfectly matched rectangular tube that the cone slides in. The coiled 'tinsel leads' act as the secondary aligning force.

Thank you so much.

I had a headache from looking so much for it before.
