Both are excellent subs. I own two Grottos, a Depth, and a Dyanmo all installed in my theater room which is 14 x 18.
I perfer the Grotto over the Dynamo. The servo controls in the Grotto makes it a bit better sounding for music and movies in my opinion. I am also considering selling the Dyanmo because four subs is a bit too much in my room.
Good luck in your search.
