DD ver. 2.2
I spent yesterday afternoon installing and running the new version 2.2 software for my DD-18. If you have a DD series sub you should definitely take the time and do this. Unfortunately, the DD’s use a serial RS232 interface and in case you didn’t notice, most laptops these days don’t have serial ports on them and the USB to serial port converters are a hassle, so I had to drag my desktop unit down stairs to the sub.
Well I’m glad I did. The response graph has gone from looking like a topographical map of the Rocky Mountains, to a nice flat (+- 3db) from 15Hz to 100Hz +. Really an amazing difference. I now have two listening positions with a flat graph where I had only one “sweet spot” before. The ability to store different EQ setups for the individual presets, defeatable low-pass crossover and the overlay of previous graph are very useful upgrade features.
For me, upgrades like this really establish the value of a product and justify the initial expense. Nice job Velodyne!
