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)?

  1. Repair Cost: If the cost of repairing the amplifier, including shipping, tax, and any potential labor charges, is around $500, it may be worth considering, especially if you have a strong attachment to the subwoofer or if you believe the subwoofer still performs well in your setup.

  2. Subwoofer Performance: The Velodyne DD-15 was a capable subwoofer in its time, but advancements in subwoofer technology have occurred since 2008. Newer subwoofers, like the SVS SB-2000 or SB-3000, offer more power, better bass extension, and improved features. If you're looking for enhanced performance and modern features, upgrading to a newer subwoofer might be a better option.

  3. Compatibility and Features: Consider the features you need, such as room calibration, connectivity options, and integration with your existing audio setup. Modern subwoofers often have advanced features that can enhance your listening experience.

  4. Budget: If your budget allows, investing in a newer subwoofer might provide you with a more satisfying and up-to-date audio experience. Both the SVS SB-2000 and SB-3000 are well-regarded subwoofers, and their performance can be significantly better than the Velodyne DD-15, especially if you have the space and budget for them.

Ultimately, the decision to repair the Velodyne DD-15 or upgrade to a new subwoofer depends on your preferences, priorities, and budget. If you're looking for improved performance and features, a new subwoofer like the SVS models you mentioned may be a good choice. However, if you have a strong sentimental attachment to the Velodyne or are satisfied with its performance, repairing it may also be a viable option.

Maybe someone has a side by side comparision of the modern SVS SB-2000 and the Velodyne DD15?

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.
