Velodyne DD15 - worth repairing the plate amp?

I had the amp from my 2006 DD18 repaired just in the last few weeks.  I used "the amp man" who you can find on ebay.  I was somewhat surprised it could still be fixed but I had it back in about a week and couldn't be happier.  Total cost to me was around $400 including shipping.  I really don't think it gets much better than this if you're using it at true subwoofer range.  Plenty of output and the servo means no distortion.  I was eyeballing SVS before I decided to see if it could be fixed and I'm glad I got it fixed.  There's no way a 13 inch sub with half the surface area could compare.

With subwoofers bigger is better with regard to longevity.  Small subs require huge excursions to do the lowest notes and that requires a lot of power and means there's a lot of pressure in the box.  These things both result in higher failure rates than with bigger subs.  Velodyne selling 10 inch, sealed subs that play flat to 20 hz is inherently problematic.  

I'm not at all bothered by my amp failure.  It's 17 years old, that's a pretty long time for electronics.  

@m-db Mine was a DD18 made in 2006.  I'm not complaining about the failure.  It went 17 years with no problems and I got it fixed for not that much money.  

I didn't have too much trouble getting the amp out but I'm not surprised it happens.  There's no adhesive but I think some sort of gasket maybe is sticky.  It'll come, worst case scenario you have to accept a little cabinet damage and pry it out with a screw driver.  

I seriously doubt the SVS-SB2000 is better than the Velodyne DD15.  Contrary to Chat GPT, the DD15 has more power and better extension than the SB2000.  A 15 inch driver has a lot more surface area than a 12.  It's proportional to the radius squared and that's 56.25 to 36.  The Velodyne is also a servo sub which keeps distortion below 1%.  You can't hear 1% distortion in deep bass so it is distortion free for all practical purposes.  I don't have anything against SVS but a sub that is $899 now is equivalent to maybe $500 20 years ago.  The Velodyne was 6 times that.  I know business models have changed and Velodyne's prices were too high but technology hasn't changed that much.  The DD15 has a 24lb magnet.  I recently looked at the driver on my DD18 when I pulled out the amp and it's an impressive looking driver.  It was not a budget product.
