Velodyne DD15 - worth repairing the plate amp?

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

Take the amp out of the speaker box.  Disconnect the two speaker wires after labeling them and disconnect the multi-pin connector.  Ship the amp wrapped in bubble to:

EBC Electronics LLC
908-458-6072
126 S 14th ave, Manville, NJ, 08835

The repair cost should be $150 to $300.

I have had EBC repair five of them.  They come back sounding brand new.

Good luck,
