Vandersteen 2W Sub Repurpose?

Not stupid.  Uniformed by the years of browsing part catalogs that some of us have wasted our youth on. :)

If you can replace a plate amp, why not call Vandersteen and see if you can buy a replacement or call/PM John Rutan at Audioconnection? I bet he can either get one for you or something that would work.
And, no, there aren't any 'stupid' questions. Only stupid people who don't ask questions, and will never know the correct answer.

Thank you for the gentle replies! I can do a "core" exchange through Vandersteen direct. That would cost slightly more than a Behringer NX3000D amp. The Vandersteen 2W is, as everyone states, "long it the tooth"  Even Vandersteen commented to that.

So an external amp allows future flexibility with other passive subwoofers. But even that has become a difficult comparison for me. 

Behringer NX3000D has ostensible advantage of DSP 
Vs.
1. RBH SA-500DSP (500W x 1Ch 4 ohms) - Subsonic Filter from 16Hz to 40Hz in increments of 1dB (16Hz, 17Hz, 18Hz, etc.).
2. Yamaha PX3 (500W x 2Ch 4 ohms ) - Subsonic Filter down to 20Hz.
3. Dayton SA1000 (1000W x 1Ch 4 ohms) - Subsonic Filter Fixed at 18Hz.
4. Klipsch RSA500  (300 watts continuous into 8 ohms or 500 watts continuous into 4 ohms)  LOW PASS CROSSOVER Continuously variable from 40-120Hz, designed for Klipsch subs.

With a gun to your head, which one? I'm sure I'm overthinking this...
Thanks again Genius Network!

I still say contact Johnny Rutan for the best info.
He knows Vandy as well as other brands and can give honest advice.-And, potentially saving you money/headaches.

Core exchange, plugs right in away you go....

Vandersteen since 1977 for a reason !!!
