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)?

Take the amp out of the speaker box.  Disconnect the two speaker wires after labeling them and disconnect the multi-pin connector.  Ship the amp wrapped in bubble to:

EBC Electronics LLC
908-458-6072
126 S 14th ave, Manville, NJ, 08835

The repair cost should be $150 to $300.

I have had EBC repair five of them.  They come back sounding brand new.

Good luck,

Yes, EBC (Matt) already received the amp. 
I made a back plate (with speaker cable pass through) to seal up the enclosure (RTV silicone around the speaker cable, used existing screws). RTV should be hard now, so will test tonight if enclosure 'holds air' (enough). Also brought one of by Class D amps up, so (assuming rain day tomorrow) will hook it up and test. Plan to run Audicy with the receiver and sub connected for initial setup, then dial in sub volume a bit more (but cannot change crossover frequency). 

 

So, did a quick temp hookup. QSC CX702 (one channel) fed from sub out (cross over at 50 Hz) to passive Velodyne DD-15. 

Very tight. 

Surprised: The QSC (class H) driving 1 channel only has clipping light coming on at higher (not crazy, but loud) listening levels. 

Does someone know what impedance the Velodyne driver has? 4 Ohm?

Assume the driver is not 2 ohm, I will try bridged mode (and make some better cable connections, very sketchy right now for the quick trial setup). 

If so, I am using all of the QSC's 825 Watt! 

8 Ohms:
425 W per Channel (Full Range, 0.03% THD)
4 Ohms:
700 W per Channel (Full Range, 0.05% THD)
8 Ohms:
475 W per Channel (1 kHz, 1% THD)
4 Ohms:
825 W per Channel (1 kHz, 1% THD)
2 Ohms:
1200 W per Channel (1 kHz, 1% THD)
16 Ohms:
850 W Bridged (Full Range, 0.1% THD)
8 Ohms:
1500 W Bridged (Full Range, 0.1% THD)
4 Ohms / 8 Ohms:
2400 W Bridged (1 kHz, 1% THD)
