The bass chassis is different as the "old" SEAS bass driver is not in production anymore.
My dealer told me that the driver(amps) should be different,
but I think he want to sell new DSP..
I dit compare my 8k(have no 8.2k..) and
the only mechanical difference I found is the different gap between the head and the "woofer".
This depends how precise the spike fit to their counterparts and that is changing the gap-but that is very minor.
But there is major reason for the different gap.
The spike have the same lenghts and shape,
but the female cone is less deep.
So the spike cant go in deep enough and that causes the diffent gap.
But we are talking here about 5mm.
