I have a set of rosewood Velodyne DD-10 subs in perfect condition. I have an extra set of sharp spikes for them in addition to the stock feet and blunt spikes.
Working down to one system, I want to sell as a stereo set as this is what you really need for great bass.
These were used for iconoclast cable development, so they were treated well.
$3,200.00 for both subs. These come with special RCA for the Digital EQ into a monitor and RS-232 master to slave sub connection. A set of TPC RCA gen 1 will be to your custom length from the preamp to the subs will be provided as well.
