New IB subs need ID - have you seen these?

[addict2speaker]

Hello IB fans!  Full disclosure, I am a speaker parts dealer and a fellow Speaker Addict.  I need your help to ID a mystery speaker

Some -Made in USA- IB speakers with under-hung design (short coil/long gap) have been presented to me but I have no info on them.  Trying to decide if I should take the couple pallets available and determine value. 

Crossing my fingers, maybe someone here has seen or heard of them and can help me with ID - I will also offer them to anyone here in the "for sale" thread at a great group buy offer if you can help.  Kind of odd as they are 8 and 10"... but looks like a very well made speaker

attached are pics of the 10", the 8" uses the same underhung motor and looks identical.  They have a magnet boot but we cut it off to show the magnet slug and plate thickness.  Clearly an IB woofer.  Look promising.  




Hoping someone can help

Many thanks

Cameron

Sorry never seen anything that looks like that.

Given the add-on to the magnets I wonder if they are prototypes

Thanks for the reply.  Could be but there are 200pcs of the 10" so a bit much for a proto I would think.  It was a USA builder that would do small batches
