Velodyne DD vs DD18plus?

Sounds deeper, more melodic and very fast. Very "effortless". The software also allows the sub to integrate almost seamlessly with my room, which is hard to pressurize. Non-sonically, I really like the way the remote now has a display on the sub so that adjustments if necessary for different music can be made on the fly.

Thanks for advice. I will look for a used dd18+ when they start to come out on the market. Good thing to have display on the sub itself.

I am also considering JL Gotham 213 (someday...not now).
