IMHO get NOTHING more recent and keep repairing your old one.
Getting new is taking too much chance on reliability while overhauling old one will give another life and keep going.
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)?
