Default CSS SDX7 still viable?

I believe they are NLA but I can still source some locally, and maybe somewhere o/s still has them for less?

Looks like a nice high excursion woofer for a FAST design.

Though, xmax looks too good to be true? Do they perfrom as per specs?

SDX7 is a fantastic woofer. I know that there are still some in distribution. Get them while you can. There is one easy mod that i consider mandatory,

Doesn't make them any less good than they are.

or, how do those relate to a particular user's application?

So far the worse thing that I've experienced with the SDX7, or the CSS FR/WR125 is the very disturbing sound when over driven - somewhat easier to do in a mis-tuned or under-damped vented enclosure. I've not heard it in a fair range of sealed or critically damped vented designs - at least not at my listening levels (below 90dB on average)
