@m-db i’m a little late to the discussion. Are you saying there is new firmware for the DDplus series? Can you elaborate?
Early this year my pair of DD10plus subs weren’t responding to the remotes, so I sent them to the amp man. I wish I had known about the guy in NJ since I probably could have driven the plates there. Amp man seemed to struggle with various issues, but he did get them working perfectly.
I’m glad Velodyne is back in business selling subs. I really like my subs and run hem well below 40hz using the eq, since my TAD CR1’s go down to high 30’s.
One of the things that drew me to The plus series is that they were designed to play really low bass. I’m actually running mine in a huge room and I also keep them on sistrum stands 20” off the floor, which reduces output, but I feel makes them sound more articulate.
Since I’m in a city condo loft, I didn’t want massive bass to avoid complaints.
Suprising, but even a pair of 10” drivers gives me the kind of subtle, deep bass I’m looking for, and does double duty for 2 channel and Home Theater, even though I leave the servos at the highest setting, even for movies.
I also like that I can change the slope on the fly, for bass shy recordings.
