I have a Velodyne SPL 1000 that I purchased new in 2000 for $800, on sale from 1K. It has been in constant, moderate use all of those years in both 2 channel and HT applications. I know this sub was a step down from the DD series of the day, but it makes wonderful thump from a small footprint. If and when this sub poops out, I would first pull the amp and look for blown fuses or loose connections. If the amp is truly shot, I would buy a new plate amp from Parts Express or Madisound. The quality of the the driver and the build quality of the enclosure are both worth the addition of new amp. Note: I wouldn't spend more than $200 - $300 on the amp.
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)?
