Velodyne DD15 - worth repairing the plate amp?


The amp in my 2008 Velodyne DD15 is dead as a door nail. 

How good is this old marvel compared to today's offerings?

Worth investing another $500 (to have amp repaired, incl roundtrip shipping, tax, etc)? Or just use as passive sub?

How does it compete to modern subs, for example SBS SB-2000 or SB-3000 (both under $1k pre owned)?

WayTooMuchStuff: Will run it as passive with external amp until EBC sends the amp back. Put the back plate on, need to seal up (silicone) the speaker cable pass through hole. Then get the Class D amp and plug it in, see what happens. 

The mini DSP uses a microphone and computer to equalize the sub much like the Velodyne software. But it is more sophisticated. They also make many other products for home and studio.https://www.minidsp.com/applications/subwoofer-tuning/dual-sub-with-mso

Now an unrelated question: my main system (audio, TV) is in an extremely larger volume room (2 1/2 stories high, open on 2 sides to other 2 1/2 story foyer, and one story dining room and kitchen (guessing 1800 sqft plus big volume). I use Dayton UM 18-22 in sealed enclosure driven by LT1300 (taken from Elemental Design A7-450 sub). 

When the Velodyne amp comes back, is it possible to ADD it to the main system and pair it with the Dayton UM 18-22?

Or is it not a good idea to pair a 'controlled' (Velodyne, sealed) sub with an 'uncontrolled' sealed. 

Or worse, pairing two different (any) subs?

It could work. Mini DSP mentioned above is made for what you want to do. I’ve never tried one. But I’ve heard it works great. Look it up on YouTube. If interested.https://www.youtube.com/watch?v=E4OY0MhMKTc
