The best bet is always to demo both speakers with some material of your choosing. You've got the 7002's in hand, so you are already familiar with them. If you like the DefTech's, you certainly would be well served by a full DefTech system, and they are good speakers, but an audition of the Rockets could be informative. You might consider checking out
AudioEnvy to see if a Rocket owner will let you take a listen -
maybe even somebody with Outlaw gear.
