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)?

I have the older Velodyne F-1500 been in continuous use for 30 years. Starting to. notice some odd low level sounds fluttering buzzing. Would that be caps needing replacement. Still sounds great to me just noticed the sound when I am up close to it and the level is low. Thinking I may try to re cap myself. Anyone here done it? how difficult is it?

@jomolu Something simple to try would be to rotate the driver 180 degrees, mindful of over tightening the fasteners. Even with no improvement it can hurt.

That is a great idea, kind of like rotating your tires. Not sure if it would  have any effect on the sounds I am hearing. I would just like to replace all the parts in the amp that may be bad do to age.

Hello,

Does anyone out there have the schematic for the DD15 DSP circuits?

I found the schematic for the class-D amplfier circuit that is used in several Velodyne subwoofer models on line but that's all I can find. 

Thanks in advance.

I have no idea what the 2019 sale to GmbH may have regarding any of the Plus' processing and functionality. I don't believe there's been a processing upgrade. I would have expected at least a smart phone interface. May be there is?

Compared to the basic Digital Drive the vastly simplified Velodyne Plus processing was never properly reviewed. While the Users Manuals described the how to functions they lacked any what to listen for suggestions.

Regardless of the users satisfaction with the Plus' initial Auto EQ settings the simple Drag and Drop functionality of the unreviewed Frequency Response and Parameters Screen (page 10-11 of the User Interface Manual) made the previously tedious DD manual adjustments now simple and on the fly.  

I'm guessing soon after the release of the Plus there may have been many issues that interrupted a substantial marketing strategy for the only idiot proof subwoofer I'm aware of.    

This reporting may be of some interest.
